This is education, not advice
The information here is written for the general reader and does not replace a personal dermatological consultation. It cannot tell you whether the pigment on your face is melasma, how active it is, or how your skin will respond to treatment.
No outcome is guaranteed
No treatment can be guaranteed. How much pigment lightens, how long the change holds and how the skin settles afterwards vary between individuals, and a result is judged honestly only after the skin has had time to settle.
Melasma is a tendency, not a lesion
Melasma is driven by ultraviolet exposure, hormonal change and a genetic tendency, and neither a laser nor a peel changes any of those. Both can lighten pigment for a period, both are followed by maintenance, and the condition usually recurs.
Treatment can make melasma worse
Melasma-prone skin produces more pigment in response to inflammation, and both a laser and a peel create inflammation deliberately. Rebound darkening is a recognised outcome rather than a rare accident, and it is why assessment, low settings and a test spot come before a course of treatment.
