In this part of the article we will find out about various skin color problems and treatment. With change in melanocyte distribution in the skin, you get many discolored spots and pigmentation problems. You may also get the problem of losing pigments from skin, as happens in vitiligo.
More pigments cause different skin problems. Some of them are:
Sun exposure accentuates all of these problems. As you know, sun makes skin produce more melanin and that increases darkening problems.
Skin Color> Bleaching>
What about bleaching of the skin discoloration? Here we have to address two concerns:
1) Stopping formation of new melanocytes at the pigmented spot, and
2) Removing the existing color on the pigmented spot.
Scientists have found that an enzyme called tyrosinase activates the production of melanin. This enzyme activity must be stopped on the discolored spot so that more melanin is not formed there. The common bleaching agents that help to stop formation of new melanin, are discussed below.
Currently the US FDA recognizes only hydroquinone as a bleaching agent. Other ingredients used in bleaching creams are called brighteners, lighteners, etc. Some of the common ingredients that can be used to stop further melanin getting produced are hydroquinone, kojic acid, and azelaic acid. Research is being conducted on many other molecules and some of them are getting incorporated in bleaching formulas.
The second problem, as we said is to remove the existing excess melanin. This can be done by exfoliating the skin and bringing fresh skin in its place. For that AHAs and tretinoin are commonly used.
You should consult your doctor and use a formulation that will not only remove the existing color, but also stop further color getting added. There are many configurations available and your doctor is the best person to address this. Take care that you do not use any product that irritates your skin and also avoid application on normal skin.
