In short. The honest no: pregnancy, photosensitising medicines, active infection, recent tanning, keloid tendency, very dark skin, and goals this treatment cannot meet.
Key points
- A contraindication is not only a medical one.
- A patient who wants the spots gone permanently, who expects the treatment to tighten the face, or who will not use sun protection is a patient who will be disappointed, and the disappointment is avoidable by saying no at the consultation.
- A clinic that declines is doing its job.
Most writing about this treatment explains who it suits. This article does the opposite, because the patients who should not have it are the ones most likely to be sold it: the risks are higher, the results are less predictable, and the sales conversation is often word for word the same.
When the answer is simply no
Pregnancy and breastfeeding are usually reasons to defer. Not because harm has been demonstrated, but because the treatment is elective, it can wait, and the hormonal changes of pregnancy make pigment unpredictable and prone to worsening. Patients taking medicines that increase sensitivity to light — some antibiotics, some acne treatments, certain diuretics and herbal preparations — should either wait or have the prescription reviewed, because the reaction is unpredictable and can be severe.
Very dark skin tones are generally unsuitable, and the honest alternative is a longer-wavelength laser with a proper assessment. A tendency to raised or keloid scarring is a further reason for caution, as is any active infection, cold sore or inflamed rash in the area.
Unrealistic goals are a contraindication too
A contraindication is not only a medical one. A patient who wants the spots gone permanently, who expects the treatment to tighten the face, or who will not use sun protection is a patient who will be disappointed, and the disappointment is avoidable by saying no at the consultation. A clinic that declines is doing its job.
The situational reasons to wait
Recent sun exposure, a tan, or a holiday in the sun planned within the next few weeks all argue for waiting. So does an important event in the diary: the week after a session is not the week to be photographed, and the darkening is visible. If you have melasma-type pigment, or a history of pigment problems after laser treatment, the risk of making the condition worse is high enough that the plan should begin with diagnosis and topical treatment rather than with a device.
There are also reasons to wait that have nothing to do with the skin: an unsettled budget, a decision made under pressure at a beauty counter, or a plan you cannot yet explain back to someone else in your own words.
Do not proceed if
- You are pregnant, taking a medicine that increases light sensitivity, or have active infection or broken skin in the area.
- You have melasma-type pigment, very dark skin or a tendency to raised scarring, and no alternative has been discussed.
- You are being pressed to pay before an assessment, or the promised result is one that no treatment can guarantee.
Saying no is not a judgement about you; it is a judgement about the match between the treatment and your skin. The clinics worth attending are the ones that say it, and then tell you what would suit you better.
Frequently asked questions
Can I have IPL while pregnant?
Treatment is usually deferred. Harm has not been established, but the treatment is elective, it can wait, and pregnancy makes pigment less predictable and more prone to worsening.
Is there any skin type that should never have IPL?
Very dark skin tones are generally unsuitable, because the contrast between the target and the surrounding skin is too small for the treatment to be selective. The usual alternative is a longer-wavelength laser, planned from an assessment.
What if I take a medicine that affects my skin?
Tell the clinic about everything you take, prescribed or not, and let them decide whether it matters. Some common medicines and herbal preparations increase sensitivity to light, and the reaction is not always predictable.
Risks & Limitations
- Pigmented spots darken before they flake away; that darkening is expected and is not a burn — blistering, crusting or increasing pain is.
- Post-inflammatory hyperpigmentation is a real risk, is more common and more stubborn in darker skin, and can take months to settle.
- Burns and blistering occur, particularly on tanned skin, with settings chosen for the device rather than the skin, and where passes overlap the same area.
- Treated skin can occasionally lose pigment rather than gain it, leaving pale patches that are difficult to treat.
- Scarring is rare and usually follows a burn or an infection in treated skin; a tendency to raised scarring is assessed before treatment.
- No result is permanent. Pigment returns as the skin continues to produce it, and sun exposure is the main thing that decides how quickly.
- The treatment changes colour, not contour. It does not tighten, lift, fill or remove wrinkles.
- Eye protection is worn by everyone in the room, because the light can injure the eye.
- Individual response varies; no outcome can be guaranteed.
When to Seek Care
- Blistering, severe or increasing pain, or a wound that is weeping or crusting after a session.
- Skin in the treated area becoming markedly darker over the following weeks rather than fading, or developing pale patches.
- A cold sore, a spreading rash or a fever after treatment.
- Any pigmented spot that is new, changing in size, shape or colour, or that looks different from the others on your skin.
- Frequent severe flushing with other symptoms, which needs a medical assessment rather than a cosmetic plan.
