Polyhydroxy Acids, commonly abbreviated as PHA, belong to a group of chemical exfoliants used in skincare. They are milder alternatives to alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), providing gentle exfoliation and other skincare benefits. PHAs are suitable for various skin types, including sensitive skin, and are known for their hydrating properties.


Polyhydroxy Acids (PHA)


Polyhydroxy Acids are synthesized compounds and belong to the same family as AHAs. Gluconolactone and lactobionic acid are common examples of PHAs, offering unique characteristics that make them suitable for those seeking a more gentle exfoliation option.


PHAs are generally well-tolerated by most skin types, including sensitive skin. Their larger molecular size allows for slower penetration, resulting in less potential for irritation compared to traditional exfoliants.


Gentle Exfoliation

PHAs help remove dead skin cells, promoting a smoother and brighter complexion without the harshness associated with some other exfoliating acids.


PHAs have humectant properties, attracting and retaining moisture in the skin, making them suitable for individuals with dry or dehydrated skin.

Antioxidant Effects

Some PHAs, like lactobionic acid, exhibit antioxidant properties, contributing to protection against environmental stressors.
