Hyperpigmentation Requires Control of Pigment Production
Hyperpigmentation is the build up of pigment in skin. But doctors dont know exactly what causes the dark pigment melanin to clump in a particular spot, forming large blotches. Research has shown skin bleaching is effective therapy.
The newest skin bleaching products were developed by chemists for home use. They inhibit pigment production and slow the growth of existing pigmented cells. The deep color fades as dark cells are replaced with new skin, helped along by exfoliation.
Up-to-date topical applications are formulated with all-natural skin lightening ingredients such as kojic acid. Older potions use chemicals that have clear health warning, such as hydroquinone and mercury. Any bleaching regimen requires repeated applications, over time, to fade hyperpigmentation.
Melasma
This is the most pronounced example of hyperpigmentation. The dark pigment melanin builds up near the skin surface, forming grey or brown patches of skin with uneven edges. Melasma rises most often in skin exposed to the sun. There is no known cure.
Skin bleaching products work to impact the pigmentation in melasma. They promote degradation of melanin, inhibit its formation, and retard the growth of new melanin
Ninety percent of melasma develops in women. Estrogen may make melasma appear. Women taking hormone therapy at menopause or on oral contraceptives are most at risk of melasma, with pregnant women also affected.
Since chemicals are out, there are natural acids and vitamins shown to impact melanin. As previously mentioned, one is kojic acid. Its used as a health supplement in Japan. Other ingredients to look for include ascorbic acid (Vitamin C), and arbutin, which is a natural substance found in plants. Vitamins E and B-3 may also be in some products. Bleaching products are available over-the-counter. Since many find hyperpigmented skin and melasma embarrassing, they appreciate the privacy of skin lightening at home.
