You should keep some facts in mind about this condition.
Who is at risk?
The people most affected by melasma are women in the age group of 20-40. This condition is less common in older women, and if you are taking estrogen replacement therapy, then you are not very likely to be affected. Men are seldom victims of this condition.
People who have a dark complexion have more to fear because dark skin tends to attract this condition. This condition is brought on by sun exposure; therefore, chances of getting it are high in summer and spring.
Melasma causes change of the skin color pattern. Three different patterns of symmetrical pigmentation on the face are the characteristics of melasma. The most commonly affected areas are the central face, the cheeks, forehead, upper lip, nose and chin. It can cause pigmentation on the forearms also. However, this is quite rare.
How can it be treated?
There is no actual way to treat this condition. You do not have special foods or diets or vitamins or even any lotion that can promise to treat this condition or, for that matter, any other form of pigmentation. You should therefore stay away from such fakers.
What you can do is use a sunscreen with a high SPF, for example, a broad-spectrum sunscreen like Anthelios SPF60 in the morning and Lustra at night. Doing this regularly will help improve your condition. You should not give up on these sun protection products and keep using them regularly because they will keep you from any risk of a relapse of melasma.
Some treatments like IPL or intense pulsed light have shown to improve conditions of melasma and also other forms of facial pigmentation. Cutera 600 IPL is especially effective because it has been optimized for reducing unwanted facial pigmentation.
Besides all these treatments, the best you can do is avoid the sun as much as possible and otherwise always use a sunscreen everyday. This will keep you from becoming a victim of melasma.
