How long does skin brightening treatment take to work for melasma?

Melasma causes brown or grey-brown patches, commonly on the face, when pigment-producing cells become overactive. Sunlight and visible light can stimulate this activity, and heat or hormonal changes may also influence it. A clinician may use topical treatment, a peel, light-based treatment, or a carefully selected combination. Melasma lies at varying depths, so surface brightness can improve before the overall pattern settles. Some procedures can irritate sensitive skin and temporarily deepen the patches, particularly when aftercare is not followed.

Follow the prescribed routine for the full interval advised, and do not increase strength or frequency because progress looks slow. Use sunscreen and physical light protection every day; a hat, shade, and gentle heat avoidance may also help. Keep cleansing and moisturising simple, and report stinging or peeling that does not settle. Compare photographs taken in similar light instead of checking the mirror several times a day. Tell the clinician about pregnancy, breastfeeding, hormonal medicines, and previous reactions before a procedure or new product.

Contact the clinic if patches become markedly darker, painful, blistered, swollen, or persistently inflamed after treatment. Seek a diagnostic review if a spot is one-sided, rapidly changing, bleeding, or crusting, since a new or changing mark should not automatically be attributed to melasma. If there is little improvement by the planned follow-up, the diagnosis, trigger, or treatment intensity may need reassessment.

How will you confirm that these patches are melasma? Which treatment is appropriate for my skin tone and sensitivity? What should I do if the patches darken after treatment? How will we maintain the improvement and when is follow-up due?
