Anyone who is familiar with skin care knows what AHAs and BHAs are. But if you’re new to the skin care and beauty game, it is helpful to know the terminology and what certain ingredients are responsible for. This will help out greatly when it comes to deciding what type of products to buy. In terms of skin care, AHAs and BHAs reign supreme.

AHAs

The term “AHA” stands for “alpha hydroxy acid.” This type of acid can be found in fruits, plants and milk. The reason AHAs are so popular in everything from creams to serums is because of its excellent exfoliating properties. Scientific research discovered that alpha hydroxy acids work effectively at reducing the signs of aging by diligently lessening the appearance of fine lines and wrinkles when high concentrations of AHAs are applied to the skin.

More advanced skin care technology has now found a way to synthesize (reproduce) the effects of AHAs and are able to develop even more powerful AHA formulations. These are most commonly used in acid/chemical peels. Products that include AHAs work to brighten dull complexions and fade the signs of aging, while promoting a more radiant look and tone. There are different types of AHAs that are religiously used as part of many beauty products, namely Glycolic acid and Lactic acid. The downside to AHAs is that they can be too potent for the skin and often result in redness or irritation.

BHAs

BHA stands for “beta hydroxy acids” and works in very much the same way as AHAs. BHAs also contain exfoliating properties but tend to be less harsh on the skin. Unlike AHAs, BHAs come from synthetic sources (not natural), such as salicylic acid, benzoic acid and buteric acid. Because of its gentler properties, BHAs are widely used in skin care products that target large pores, blackheads, blemishes and acne prone skin.

Both AHAs and BHAs can be found in over-the-counter products as well as those prescribed by a doctor. When looking for products that contain AHAs and BHAs, be sure to check the label to find out the percentage it contains. Pick a concentration (pH level) that works with your skin type. The lower the pH, the higher the acidity, which means it will be absorbed quickly into the skin. The most common level ranges between 5-10%.

AHAs tend to dry the skin out so moisturize after using an AHA product. Before using any skin care product that contains these ingredients always do a patch test first and discontinue using it immediately if your skin has an allergic reaction. Sensitive skin types shouldn’t use these types of products more than once to twice a week or as directed by a doctor.

If you’re planning on getting a chemical peel (these contain between 20-30% pH), shop around and make sure the person you choose to perform your peel is a licensed esthetician who knows what he/she is doing.
