What is Pha used for?
It has been reported that Poly-Hydroxy Acids provide similar effects for our skin as AHAs but do not cause the sensory irritation responses2. Such responses can limit the use of classical AHAs. In addition, it was found that PHAs provide the following skin benefits2: Sensitive Skin Care PHAs have been found to be compatible with clinically sensitive skin, including rosacea and atopic dermatitis, and can be used after cosmetic procedures Humectant and Moisturisation Properties PHAs provide additional humectant and moisturization properties compared with AHAs and can enhance stratum corneum barrier function, therefore increasing the skin’s resistance to chemical challenge. Antioxidant Properties Most PHAs also possess antioxidant properties Acne Treatment PHA-containing products were used in combination with retinoic acid in treating adult facial acne and were found to be well tolerated Anti-aging Properties PHAs plus retinyl acetate (pro-vitamin A) in a cream base exhibited significant antiaging skin benefits such as skin smoothing and plumping Skin Lightening Properties PHAs plus hydroquinone showed excellent improvement in anti-aging and skin lightening parameters Broad Application PHA-containing products were shown to be compatible with African American, Caucasian, and Hispanic/Asian skin and provided significant improvements in photoaging in these populations. Conclusion Poly-Hydroxy Acids (PHAs) provide similar effects as Alpha-Hydroxy Acids (AHAs) but do not cause the sensory irritation responses that can limit the use of classical AHAs. PHAs have been found to be compatible with clinically sensitive skin, including rosacea and atopic dermatitis, and can be used after cosmetic procedures
