Are Alpha Hydroxy Acids Safe for Dry Skin?
- By:-- --
Alpha hydroxy acids have become standard treatment for a variety of skin problems – including dry skin. Lotions containing low concentrations of the acids are available over the counter, and in higher concentrations from your doctor. The acids are also used for skin peels, administered by a professional. Using a good shielding lotion as a moisturizer prevents and treats dry skin on a daily basis, but, used correctly, alpha hydroxy acids may also be beneficial.
The most common alpha hydroxy acids (AHA’s) are lactic acid, a derivative of sour milk, citric acid, from oranges and other citrus fruits, and glycolic acid, a derivative of sugar cane. Although they have been used for centuries – Cleopatra used to bath in sour milk – they have now been refined, and are included in many cosmetic and beauty products.
How do they help dry skin? Their primary function is exfoliation. Dry skin is often caused by an excessive build-up of dead skin cells on the surface. Alpha hydroxy acids weaken the bonds that hold dead skin cells together, loosening their hold on the surface and leaving the skin fresher, smoother, and younger looking. They also stimulate production of collagen, giving the skin more support and increasing the thickness.
Many studies have shown that using a product with an alpha-hydroxy acid concentration of at least 8 to 10 percent is effective in restoring elasticity, diminishing fine lines and wrinkles, lightening areas that have become dark as we age, and reducing dry skin.
How do you choose the right product? Remember that these are powerful acids. They seep into the skin, and can do so too deeply. When first applied, they will sting for 20 or 30 seconds, but if the sting lasts longer, the product you’ve chosen is too strong. They can also increase sun-sensitivity so you should definitely use sunscreen. It’s best to start with a product of low concentration to ensure you don’t damage the skin, and choose a product with other natural ingredients so you don’t exacerbate the situation by using chemicals that cause dry skin. Applying two to three times a week should suffice.
Although alpha hydroxy acids may be helpful, they do expose the skin to the elements and make it more sensitive, so it’s important to also use a shielding lotion. A good shielding lotion bonds with the outer layer of the skin to form a barrier that protects against harsh environmental pollutants, and locks in the natural moisture. It’s your first defense against dry skin. Using the AHA lotion a few times a week, and the shielding lotion daily, you could start looking younger in just a few days!
