how can I reduce the skin melanin production.Is it possible by vitamin C(Ascorbic Acid)?

You cant control the melanin production of your skin, it is part of your DNA. You can buy lightening creams to offset your colour.

You can remove sun damage & hyperpigmentation to get back to the color you had as a young child (or the color of the unexposed skin under your clothing).

A great sunblock like Anthelios 60 or Neutrogena for babies SPF 60 will protect your skin from extra darkening. Hats/protective clothing/seeking shade outdoors helps too.

There are many ways to exfoliate and restore your base color. Soaking and gentle scrubbing, Vitamin C serums, products with AHA/Glycolic/Kojic acids, papaya soaps.

Some people use peels or Retin-A but with the different reactions, it's best to be monitored by a professional (aesthetician, dermatologist) if you're not experienced with these stronger products.

Cremes and gels containing hydroquinone, sepiwhite, alpha-arbutin can help fade extra-dark patches, and permatanned(areas that have years of sun exposure..often the forearms, forehead & face, back of neck, back of hands) to match your body's natural color. Those do affect melanin production.

However my aesthetician explained that they're(esp. HQ) used temporarily to fade darker areas to harmonize skin tone, not as a all over color changer on already even-toned skin.

I'm finding these forums really helpful.
