What's the best makeup or concealer that covers up melasma?

Mary Ellen, as an industry makeup artist, I've encountered many "problems" on  skin that need to be camouflaged. Melasma is hyperpigmentation that usually arises from birth control pills or pregnancy, (hormonal) and aggravated even worse by the sun. Once you have it, it's hard to get rid of, but there are procedures that can help dramatically. A non-invasive peel you can do is the VI peel. It's conducted in a dermatologists office or med spa. It's fantastic for lifting melasma and there really is no downtime, just a few days of peeling. The new skin that turns over is beautiful and drastically more even toned. This is NOT a chemical peel, it's a very simple skin shedding peel, but goes into the dermis deeper to "lift" the dark pigmentation. Another procedure that could be helpful is called Cosmelan. It's a "mask" your doctor applies that you wear for hours at home. I've read the results are dramatic with this one. It can be costly, anywhere between 800-1000.

As far as makeup goes, the best for covering stubborn melasma is Dermablend. This foundation and concealer is used for trouble areas, like scars and tattoos. If you find that it streaks, then your application is incorrect. It's very concentrated, so to sheer it out, you can add a bit of moisturizer to it and mix and apply w/ a makeup brush. Use a latex sponge (as opposed to non-latex) to blend out. Another great product for covering melasma or any hard to conceal imperfection, is MAC Full Coverage Foundation. It comes in a vast array of shades in neutral cool and neutral warm and can be found easily at your local mall.

Cover Fx Cosmetics is the best line I have ever worked with for concealing skin conditions including Melasma. For 6 years since I began using the product, I have been able to balance out skin with the condition to a point where you can't see the pigment difference.  I recommend reading the Cover Fx website which is www.coverfx.com.  It is not a selling website.  It is an educational website that will talk to you not only about the condition but also give you tips on how to apply makeup as simply as possible.  The website will then help you locate a store near you or you can call their 800 number if you can't find a store in your area.  In the meantime, keep using a good sunscreen as additional exposure to the sun can make melasma spots darker.  I suggest using a full sunscreen even if you are already using a moisturizer with a sunscreen to make sure you are getting sufficient protection.
