Glycolic acid is an effective alpha hydroxy acid (AHA) typically used in anti-aging skin care, but it's also good for treating sensitive skin, acne and hyperpigmentation, especially when it is in a buffered state. Derived from natural sugar cane, glycolic acid owes its efficacy to its small molecular size; this smaller molecular size permits it to penetrate skin easily, allowing it to dissolve the "glue" that holds skin cells together. This promotes exfoliation for smoother, clearer skin.
If you are experiencing breakouts (on your face or body), glycolic acid can help reduce the amount of surface oils on the skin and help to remove blackheads and other impurities. Along with addressing acne, glycolic acid may also stimulate collagen production and improve skin elasticity overtime.
In general, AHAs like glycolic acid are safe when used according to the manufacturer's directions. However, some people can be sensitive to certain concentrations of acids. When choosing an AHA, consider the advantages of a buffered glycolic acid as opposed to one that is non-buffered.
Some acids are more acidic than others, and can sometimes cause irritation. Non-buffered acids are generally stronger than buffered acids, and while they may yield faster results, they are more likely to cause redness, irritation and visible skin flaking or peeling.
Contrary to popular belief, buffered acids are no less effective; in fact, with buffered acids there is less discomfort and redness – and exfoliation takes place in a less visible manner. Additionally, buffering provides a time-release quality to the product. This prolonged effectiveness is thought to give better long-term improvements.
If you are looking for an anti-aging product that contains buffered glycolic acid and will provide results without drying your skin, Wrinkle Revenge facial cleansers are an excellent choice. The line contains three cleansers designed to be used in succession, beginning with Wrinkle Revenge 1 facial cleanser. As your skin becomes accustomed to the first cleanser, you can gradually move on to the second (which contains a higher concentration of buffered glycolic acid), then finally onto the third Wrinkle Revenge 3 facial cleanser for the highest concentration.
Another anti-aging option is the Litmus Test line. Litmus Test products address anti-aging concerns, but are also gentle enough for all skin types and help to promote skin exfoliation to help treat fine lines and wrinkles while establishing healthy skin chemistry.
No matter what AHA you choose to use, choosing one that is buffered will help yield amazing results with less redness and irritation!
