Who Shouldn't Use IPL?

IPL Contraindications: The Complete Safety Guide

Updated April 2026 

---

IPL is one of the most widely-studied and safely-used light-based technologies available for at-home use. But "safe for most people" is not the same as "safe for everyone" — and one of the most irresponsible things a brand can do is minimize this distinction.

This guide exists because we believe you deserve to know, clearly and completely, whether IPL is appropriate for your specific situation before you buy a device. If IPL isn't right for you, we'd rather you not purchase than purchase and be harmed. No brand should hide this information in small print at the bottom of a product page.

The contraindications that follow come from published medical literature, regulatory guidance under EU MDR 2017/745, and standard dermatology practice. They cover skin conditions, medications, life situations, and individual characteristics that make IPL unsafe, inadvisable, or contraindicated.

Read carefully before starting — and if any of these apply to you, consult a dermatologist before using any IPL device, regardless of brand.

1. How to use this guide

This article is organized by category of concern. Read the full contraindications list before your first IPL session — not just the one that seems most relevant to you.

If any of the "absolute contraindications" in Section 2 apply to you, do not use IPL at all, regardless of any other factor.

If any of the "relative contraindications" in Section 3 apply, IPL may still be possible but requires medical consultation first. We can't tell you whether it's safe in your specific case — only a qualified dermatologist can, after examining your skin and reviewing your medical history.

When in doubt: book a consultation before you buy. It's a small investment that can prevent a significant problem.

2. Absolute contraindications (do not use IPL)

If any of the following apply to you, IPL is not a safe option. No device, no intensity level, no protocol change makes it safe.

Pregnancy and breastfeeding

IPL has never been studied in pregnant or lactating women, and the absence of data is itself a reason to avoid it. The theoretical risks — however low — are not worth taking during these critical periods. Wait until you have stopped breastfeeding before beginning or resuming a protocol.

Active skin cancer

Any history of skin cancer in a potential treatment area is an absolute contraindication. IPL targets pigmented cells, and any abnormal pigmented lesion should be evaluated and cleared by a dermatologist before considering any light-based treatment in that area.

Recent radiation therapy

Skin that has received radiation therapy for any medical reason — even years ago — has altered collagen, blood supply, and healing response. Do not treat any area that has been irradiated without explicit approval from your oncologist and dermatologist.

Photosensitivity disorders

Conditions that make your skin abnormally sensitive to light include:

• Lupus (including cutaneous lupus erythematosus)
• Porphyria (all types)
• Polymorphous light eruption
• Solar urticaria
• Xeroderma pigmentosum
• Chronic actinic dermatitis

If you have any of these conditions, IPL can trigger severe reactions. Do not use.

Active use of specific photosensitizing medications

Some medications make the skin dangerously reactive to light. See Section 7 for the detailed list. During active use of these medications, IPL is an absolute contraindication.

Active herpes simplex in the treatment area

IPL can trigger herpes outbreaks. If you have active cold sores, genital herpes lesions, or any active HSV outbreak in the planned treatment area, postpone the session until 2 weeks after full clearing.

If you have a history of recurrent herpes simplex outbreaks in an area you want to treat (e.g., lip or bikini line), consult a doctor first — prophylactic antiviral medication may be recommended before starting IPL.

Implanted electrical devices

If you have a pacemaker, defibrillator, cochlear implant, deep brain stimulator, or other implanted electronic device, consult both your cardiologist (or relevant specialist) and a dermatologist before using IPL. While direct interference is theoretical rather than established, caution is warranted.

Tattoos in the treatment area

The pigment in tattoo ink absorbs IPL light in the same way hair pigment does — but in far higher concentration. Flashing IPL over a tattoo can cause severe burns, blistering, permanent tattoo damage, and scarring.

• Avoid the tattoo entirely, plus a 1 cm margin of surrounding skin
• Do not attempt to treat "between" tattoo lines
• Do not use lower intensity and hope for the best — this is not sufficient

Fitzpatrick skin type V or VI

The skin's own melanin content absorbs IPL light before it can reach the follicle, creating significant risks of burns, hyperpigmentation, and hypopigmentation. For darker skin tones, Nd:YAG laser (used by licensed dermatology clinics) is the appropriate alternative.

See Section 4 for detailed information on Fitzpatrick classification.

3. Relative contraindications (consult a doctor first)

The following conditions don't automatically disqualify you from IPL, but require professional evaluation before proceeding.

Autoimmune conditions

Conditions that affect immune function or cause skin involvement include:

• Psoriasis
• Eczema (atopic dermatitis)
• Vitiligo
• Rheumatoid arthritis (if affecting skin)
• Scleroderma

IPL in treated areas may trigger flares or exacerbate symptoms in some cases. Consult a dermatologist before beginning.

Keloid-prone skin

If you have a history of keloid scarring (raised, thickened scars that extend beyond the original wound), IPL carries a slightly elevated risk of hyperpigmentation or altered healing in treated areas. Discuss with a dermatologist before treating.

Diabetes

Diabetes can affect wound healing and immune response. While IPL is generally compatible with well-controlled diabetes, discuss the protocol with your doctor, particularly if you have any diabetes-related skin complications (neuropathy, slow-healing ulcers, etc.).

Hormonal conditions affecting hair growth

• PCOS (polycystic ovary syndrome): IPL is safe but expect slower results and more frequent maintenance due to ongoing hormonal hair stimulation
• Hirsutism (from various causes): similar caveat — treatment is possible but expectations should be calibrated
• Thyroid disorders (especially hyperthyroidism): stabilize your condition before starting

Recent sun exposure or sunburn

Do not treat any area that has been sunburned in the past 2 weeks, or significantly tanned (even gradually) in the past 4 weeks. Skin containing elevated melanin from sun exposure absorbs IPL inappropriately, increasing burn and pigmentation risks. Wait for the tan to fade fully before treating.

Active acne or open skin lesions

Do not IPL over active acne lesions, open wounds, cuts, scabs, or any broken skin. Wait until the skin is fully healed.

Recent chemical peel or laser treatment

Wait at least 2 weeks after a superficial chemical peel, and 4 weeks after a deeper peel or laser treatment, before using IPL in the same area.

History of melasma or post-inflammatory hyperpigmentation

If you have a tendency to develop patches of hyperpigmentation in response to skin trauma, IPL can potentially trigger this. Discuss with a dermatologist; in many cases IPL is still possible but with lower intensities and additional sun protection.

4. Skin tone: why Fitzpatrick V–VI is unsafe

The Fitzpatrick scale classifies skin tones from I (very fair) to VI (very deeply pigmented) based on burn/tan response to sun exposure. Understanding where you fall on this scale is essential for IPL safety.

Full Fitzpatrick chart

Why darker skin is incompatible

IPL is designed on the assumption that hair contains significantly more melanin than the surrounding skin. In Fitzpatrick V and VI skin, the skin's own melanin content approaches or exceeds hair melanin content, which means:

• IPL light is absorbed by the skin itself before reaching the hair follicle
• Skin cells are heated instead of hair follicles
• Consequences include burns, hyperpigmentation, hypopigmentation, and permanent skin damage

This is physics, not marketing. No at-home IPL device — at any price, from any brand — is safe for Fitzpatrick V–VI skin, regardless of what the packaging claims.

What to do if you have darker skin

Professional Nd:YAG laser (1064 nm wavelength) is designed to penetrate past skin melanin to target the follicle. It is offered at medical dermatology clinics and is the appropriate technology for darker skin tones.

If you have Fitzpatrick V or VI skin and are considering hair reduction, book a consultation with a dermatologist. At-home IPL is not the right path for you, and we recommend against purchasing any at-home IPL device for your skin type.

5. Hair color: why some hair doesn't respond

IPL works by targeting melanin — the pigment that gives hair its color. If there's no melanin (or very little), there's nothing for the IPL light to absorb.

Hair colors that respond to IPL

• Black: excellent response
• Dark brown: excellent response
• Medium brown: very good response
• Light brown / chestnut: good response

Hair colors that do not respond

• Dark blonde: limited response, slower results
• Light blonde / strawberry blonde: minimal to no response
• Red: minimal to no response (melanin is predominantly pheomelanin, which absorbs light differently)
• Gray / white: no response (no melanin present)

The honest recommendation

If your hair is predominantly red, blonde, gray, or white in the area you want to treat, IPL is unlikely to produce meaningful results. No device, at any price, solves this fundamental limitation.

Alternatives include:

• Electrolysis: the only proven technology for light/white/gray hair, but slow and expensive (treats one follicle at a time)
• Professional laser with specialized protocols: limited efficacy, but some clinics report modest success on dark blonde hair with long-wavelength lasers

If your hair is mixed — e.g., mostly dark with some gray — expect IPL to work on the dark hairs and leave the gray hairs untreated.

6. Pregnancy and breastfeeding

This section exists because it's the single most common question we receive, and the answer deserves detailed explanation.

Why pregnancy is an absolute contraindication

There are no controlled studies of IPL use during pregnancy. None. This is because:

• Conducting such studies would be unethical (you cannot ethically expose pregnant women to an unproven intervention)
• Observational data is sparse and inconsistent
• The theoretical risk is low, but not zero

In the absence of evidence, the only responsible position is: do not use IPL during pregnancy.

Why breastfeeding is also an absolute contraindication

The same logic applies. Hormonal changes during lactation can affect skin pigmentation and sensitivity (many women develop melasma during pregnancy and lactation). Combining these changes with IPL's effects on melanin is unstudied and potentially problematic.

Wait until you have fully stopped breastfeeding before resuming or starting IPL protocols.

What about protocols I was already doing before pregnancy?

Pause immediately when you learn you're pregnant. Your protocol can resume after pregnancy and after breastfeeding is complete. Typically, you'll resume where you left off rather than restarting — your previously-treated follicles remain disabled.

What about trying to conceive?

IPL before pregnancy does not affect fertility, hormone levels, or pregnancy outcomes. You can use IPL up to the point of becoming pregnant, then pause until after delivery and breastfeeding.

---

7. Medications that make IPL unsafe

Many common medications increase skin photosensitivity, making IPL temporarily unsafe. This list is not exhaustive — always consult your pharmacist or doctor if you're unsure.

Absolute contraindication during active use

Isotretinoin (Roaccutane / Accutane)

Do not use IPL during isotretinoin treatment or within 6 months of stopping it. Isotretinoin profoundly affects skin healing, and IPL can cause severe scarring in patients on or recently off isotretinoin.

This is one of the strictest contraindications in IPL safety. Do not attempt to shortcut the 6-month waiting period.

St. John's Wort (Hypericum perforatum)

Commonly used as an over-the-counter herbal supplement for mood. Strongly photosensitizing. Pause for at least 2 weeks before IPL and do not resume during active protocol periods.

Pause treatment if currently using

The following medications require pausing IPL during active use (or at least careful consultation):

• Tetracycline antibiotics: doxycycline, minocycline, tetracycline
• Fluoroquinolones: ciprofloxacin, levofloxacin
• Sulfonamides: including sulfamethoxazole/trimethoprim (Bactrim)
• Certain diuretics: hydrochlorothiazide, furosemide
• NSAIDs in high doses: particularly piroxicam
• Certain antifungals: griseofulvin
• Retinoid-containing topicals: retinol, tretinoin, adapalene (pause application in treatment area 48–72 hours before session)
• Amiodarone: long-term cardiac medication with strong photosensitizing effects
• Certain chemotherapy agents: consult oncologist
• Certain immunosuppressants: consult prescribing physician

If you're uncertain

When in doubt, ask your pharmacist. Most pharmacies will confirm whether a specific medication has photosensitizing effects. Pharmacists are trained to identify these interactions and are often more accessible than doctors for quick questions.

8. Skin conditions and IPL

Certain skin conditions require specific caution.

Eczema (atopic dermatitis)

IPL is generally not recommended during active flares. When eczema is well-controlled and skin is clear, IPL may be possible — consult a dermatologist.

Psoriasis

Psoriatic plaques are unsafe to treat directly. Unaffected areas of skin may be treatable, but the overall pattern of your condition and current flares should guide the decision. Dermatologist consultation required.

Rosacea

Interestingly, IPL is sometimes used medically to treat rosacea (targeting the vascular component). For hair reduction specifically, treating the face during an active rosacea flare is not recommended. Clear, stable rosacea may be compatible with IPL for facial hair — dermatologist consultation required.

Vitiligo

Areas of depigmented skin (vitiligo patches) do not contain melanin and cannot be safely treated. The boundary between pigmented and depigmented skin is particularly problematic. Avoid treating affected areas.

Acne (active)

Do not treat over active inflammatory acne lesions. Post-acne scarring and hyperpigmentation can also affect treatment — clear skin is required in the treatment zone.

Seborrheic dermatitis

Active flares should be treated and cleared before IPL. Stable skin may be compatible.

Recent chickenpox, shingles, or similar viral skin eruptions

Wait until skin is fully healed and any post-inflammatory redness has resolved.

---

9. Tattoos, birthmarks, and moles

Tattoos

See Section 2. Absolute contraindication. Avoid the tattoo plus 1 cm margin.

Birthmarks

Most birthmarks contain elevated melanin or altered pigmentation. Avoid treating directly over birthmarks. If a birthmark is within a treatment area, work around it, maintaining a small margin.

Moles

Moles should be:

• Examined by a dermatologist before IPL if you haven't had recent skin screenings
• Avoided during IPL sessions (do not flash directly over moles)
• Monitored after IPL for any changes

If you have multiple moles in a treatment area, a dermatology consultation before beginning IPL is recommended — both for mapping (knowing which to avoid) and for ensuring none are atypical.

Freckles

Freckles contain melanin but are generally not clinically significant. You can treat over freckles, but they may temporarily darken after sessions before returning to baseline. Heavy freckling may require lower intensities.

---

10. Age considerations

Minimum age

Most IPL manufacturers, including Reliva, recommend a minimum age of 16–18 years.

Reasons:

• Adolescent skin is more reactive and more prone to post-inflammatory hyperpigmentation
• Hormonal changes during puberty affect hair growth patterns
• Treating before full hair growth pattern establishes means more new follicles will activate later, requiring more maintenance

Maximum age

There is no specific upper age limit, but:

• Hair often naturally lightens with age, reducing IPL effectiveness
• Skin healing slows with age, warranting slightly more conservative protocols
• Medications common in older adults (blood thinners, photosensitizers) may complicate treatment

Hormonal transitions

• Adolescence: wait until full puberty and stable hair growth patterns (typically age 18+)
• Pregnancy: see Section 6
• Menopause: often causes new chin/lip hair growth; IPL is appropriate but expect ongoing maintenance
• Hormonal therapy transitions: consult the prescribing physician about timing IPL

---

11. Recent cosmetic procedures

Several cosmetic procedures affect skin in ways that make IPL temporarily unsafe.

• Chemical peels (superficial): wait 2 weeks
• Chemical peels (medium/deep): wait 4–8 weeks, sometimes longer
• Laser resurfacing: wait 4–6 weeks
• Microneedling: wait 2 weeks
• Botox/fillers in the treatment area: generally not affected, but wait 1 week to allow settling
• Professional microdermabrasion: wait 2 weeks
• Sclerotherapy: wait 2–4 weeks

When in doubt, ask the practitioner who performed your procedure. They will know the healing timeline specific to your treatment.

12. What to do if you're unsure

If after reading this guide you're still uncertain whether IPL is right for you, here's what we recommend, in order of usefulness:

1. Book a dermatology consultation

A single consultation (typically €50–€120 in most European countries) can tell you definitively whether IPL is appropriate for your specific skin, medical history, and medication list. This is significantly cheaper than buying a device and discovering afterward that you shouldn't use it.

2. Ask your pharmacist about medications

For medication questions specifically, pharmacists are fast, accessible, and accurate. Most will confirm photosensitizing effects in under 5 minutes at no cost.

3. Do a patch test before a full session

If you're cleared to use IPL but still uncertain how your skin will respond, do a patch test first. Flash a small area (inner thigh or inner forearm) at the lowest intensity and wait 24–48 hours. Any significant redness, pigmentation change, or irritation is a signal to pause and reconsider.

4. Start with lower intensities than recommended

Even when cleared, beginning with lower intensities and gradually increasing over multiple sessions is safer than starting at higher intensities. Your skin will tell you what it can tolerate.

5. Honor our 30-day money-back guarantee

All Reliva devices include a 30-day unconditional money-back guarantee. If after starting IPL you develop concerns or experience unexpected responses, you can return the device for a full refund. There's no financial penalty for trying and deciding IPL isn't right for you.

13. Frequently asked questions

I'm taking a medication not on your list. Is it safe with IPL?

Ask your pharmacist. They can check for photosensitizing effects in their databases. For medications not covered here, we can't give blanket advice — individual assessment is required.

Can I use IPL if I had childhood skin cancer that's been fully cleared for over 20 years?

Discuss with a dermatologist. Generally, fully cleared and monitored cases may be eligible, but the specifics matter (type of cancer, location, treatment history).

I have one tattoo and want to treat the surrounding area. How close can I get?

Stay at least 1 cm away from the tattoo edge in all directions. Even at that margin, use conservative (lower) intensity and watch carefully for any reaction.

My hormones changed recently (thyroid, menopause, birth control change). Should I pause IPL?

Generally, no — ongoing hormonal shifts don't make IPL unsafe. They may affect efficacy (new follicle activation, changed hair pattern), but safety is unaffected. Consult your doctor if significant skin changes accompany the hormonal change.

I have very light blonde hair but dark chin hair. Can I treat the chin?

Yes, for the dark chin hair specifically. IPL will work on the darker hairs while leaving the light hairs unaffected. This is a common situation and not a contraindication.

I have PCOS and extensive facial hair. Will IPL help?

Yes, but expect slower results and more frequent maintenance. Hormonal hair growth is ongoing, which means IPL manages but doesn't fully eliminate the condition's root cause. Combined with medical management of PCOS, many women see significant improvements.

I took a photosensitizing antibiotic 2 weeks ago. How long before I can resume IPL?

For most common antibiotic courses (e.g., a 1-week doxycycline course), wait 2–4 weeks after finishing. For longer courses or stronger medications, wait 4–6 weeks. When in doubt, ask the prescribing physician.

---

The bottom line

IPL is safe for most people — but "most" isn't "everyone." The contraindications above exist because IPL uses real energy that interacts with real biology, and certain skin types, conditions, and medications change how that interaction plays out.

If any of these apply to you, please take them seriously. An IPL device that isn't right for your skin doesn't just fail to produce results — it can cause real, sometimes lasting, harm.

But if you've read this far and nothing applies to you, we'd say the same thing we'd say to a close friend: IPL is one of the best-documented and safely-used cosmetic light technologies available for at-home use. Done correctly, by the right person, it works reliably and safely.
