Exfoliate: The Importance of pH in Exfoliation

Exfoliation is key to generating noticeable improvements in the skin due to its ability to remove built-up layers of keratin – dead skin cells and debris that clog pores, slow cellular turnover, and enhance negative skin characteristics – while activating the production of collagen, the protein responsible for skin strength and suppleness.

Despite its benefits, exfoliation is either missing from most skincare regimens or implemented improperly. Contrary to popular belief, there is no such thing as “gentle exfoliation;” the only way to remove the thickened layers of keratin is through the use of highly effective chemical or mechanical techniques. Products that contain granules or microbeads are ineffective and may do more harm than good.

A product’s pH measures its level of acidity. At the very least, your exfoliant must be more acidic than skin’s natural pH of 6.5 to be effective. The lower the pH number the more acidic or effective the product is.

Over-the-counter exfoliants typically have a pH level between 3.7 and 5.
Physician-dispensed exfoliants for home use range from 3 to 4.5.
Doctor’s office peels have a pH of 2 or lower.

AloeGlyC® Renewing Exfoliant Features an Effective pH of 2.1 to 2.3.

Lexli’s AloeGlyC® Renewing Exfoliant maintains an effective pH of 2.1 to 2.3, a strength similar to a doctor’s office chemical peel. This is possible in an over-the-counter product because Lexli’s base of pure, pharmaceutical-grade aloe vera minimizes the potential for burning and irritation, making the product safe and effective for daily at-home and professional use.

Most over-the-counter exfoliating products have an effective pH between 3.7 and 5, which is not strong enough to thin the keratin layer and stimulate collagen production. Many brands will highlight the percentage of glycolic acid in their formulation but then add buffers, which raise the overall pH. For this reason, it is essential to know a product’s pH before you can determine its effectiveness.
