Does your melasma become worse over the years especially during the summer? You probably have visited your dermatologist for melasma treatment but your dermatologist has forgotten to tell you to use sunscreen. So what is the best sunscreen for melasma?
Melasma usually gets darker when it is exposed to the sun. If you don’t want to aggravate your melasma, the sunblock that you use should be mineral based. The SPF should be minimum 30.
Avoid any sun cream that contains PABA, paraben, oxybenzone, copper, and alcohol. Find one that comes with 10% zinc oxide or titanium dioxide or both.
Even you use the best cream, treating melasma will not be effective if you don’t protect your skin from the sun. Every time the brown spot is subjected to the UV rays, it will become darker. You have to check if the sunscreen could block both UVA and UVB. Protecting your face from the sun exposure is the best line of defense.
Use sunblock every day. Make sure you apply it again every 2 hours. It does not matter if the sun is not hot. Even on cloudy days, UV radiation is still unavoidable.
Hyperpigmentation is a common skin issue, which is more prevalent with age, hormonal fluctuations and skin scarring. Glycolic acid for hyperpigmentation is a widely-used alpha-hydroxy acid (AHA). It is part of alpha hydroxy, or AHA, family of acids. It is extracted from sugar cane. Like other AHAs, its main purpose is to exfoliate the skin. A clinical study showed glycolic acid, when used as a chemical peel, is very effective at treating hyperpigmentation naturally.
Glycolic acid is used to treat various types of hyperpigmentation naturally such as freckles, melasma, age spots and post acne marks. If you visit an aestheticians, your dark spots will be treated with a glycolic acid chemical peel. If you want to do it yourself, you can use over-the-counter products.
Regardless of your skin tone or types, you can have hyperpigmentation. The two major causes are pregnancy and oral contraceptives. Don’t forget post-healing acne scarring can also contribute to brown spots. Any trauma on the skin will eventually lead to hyperpigmentation.
When you apply glycolic acid on your skin, it penetrates the surface of the epidermis which holds clusters of dead cells. It loosens the binding so the dead cells can be easily removed. Its exfoliating action helps reduce the appearance of dark spots by slowly peeling discolored patches of skin. In the end, your complexion should be smooth and the shades of your skin should be more even.
Glycolic acid is available in various concentrations and acidity levels. Over-the-counter products contain between 5 and 20 percent concentrations of glycolic acid which is ideal for home use. Stronger preparations like facial peels which are done at clinic come with acid concentrations of 20 to 70 percent. The concentration depends on your skin type. For example, if your skin is sensitive, then you should use low-concentration glycolic acid. This is to prevent any irritation on your skin.
Glycolic acid for hyperpigmentation is considered mild. So the result is not instant. Don’t expect quick results with facial peels that use stronger concentrations. It will take some time to see melasma, freckles or liver spots reduced. You have to be patient it may take p to six months before the spots begin to fade.
After treating hyperpigmentation with glycolic acid treatments, your skin will be extra sensitive to the sun. They cannot prevent the formation of future dark spots. It is best that you wear a good sunscreen the whole day to prevent any new spots from appearing and existing ones from becoming darker. You will waste all your efforts in lightening brown spots if you fail to follow this step. It just needs one day of excess sun to destroy all the results of the treatment.
You may encounter redness or mild peeling. If you are in such a situation, reduce the concentrations. But if the conditions get worse, then you should not use glycolic acid.
