The two hydroxy acids, AHAs and BHAs, are found in both facial and body skincare products. They are effective at removing skin knots and promoting cell turnover. This can lead to an improved appearance of wrinkles, age spots, and other blemishes. Both AHAs and BHAs can diffuse easily into the skin and cause irritation in some individuals. If this occurs, it is best to discontinue use of the product and consult a dermatologist.
