Melasma is such a dicey topic. Lasers is still quite the mainstay of treatment of melasma.
But what does matter, is the a combination of a few factors in my opinion:
SUNBLOCK cannot be overly emphasised.
No sunblock is virtually asking for trouble.I like using oral supplements.
TOMATO EXTRACT and P LEUCOTOMOS together i find works well for my patients. Some think its voodoo medicine - I find that it works well.Keeping your skin well hydrated and healthy with your usual skin care regime is useful. LASERS are drying in nature as they are energy based.
In short:
Normal skincare
Appropriate moisturiser
Sunblock
Oral supplements
