What if a pigmentation treatment makes dark spots worse instead of better?

Light and laser-based pigmentation treatments generally improve the appearance of dark spots over a course of sessions, but it is worth knowing what a normal part of that process looks like versus a genuine complication, since they can look similar in the first few days.

What’s normal

Treated spots commonly look darker for several days immediately after a session, before flaking or fading over the following one to two weeks. Some redness or sensitivity in the treated area is also expected. This is a well-recognised part of how these treatments work, not a sign that something has gone wrong.

What’s not normal

Burns, blistering, open skin, or new pigmentation appearing in areas that were not being treated are not an expected part of recovery. Persistent darkening that does not improve after several weeks, or pigmentation that looks noticeably worse than before treatment with no sign of settling, should be raised directly with the clinic that performed the treatment, rather than waited out.

Why this can happen

Treating skin that is tanned, treating a skin type unsuited to the specific treatment or settings used, or inconsistent aftercare (particularly sun exposure during healing) can all increase the risk of the skin reacting with more pigmentation rather than less. This is part of why clinics assess skin type, tan and treatment history individually before each session, rather than using a single approach for everyone.

What to do if it happens

Contact the treating clinic promptly and describe exactly what you are seeing, since timing matters for how a reaction is managed. Photos taken at each stage can help a clinician assess whether what you’re seeing is within the normal range or needs a different approach. If a clinic dismisses a genuine concern without a proper assessment, seeking a second opinion from another qualified provider is a reasonable next step.
