What is PHA in Skincare?

Published in Skincare Ingredient 2 mins read

In skincare, PHA stands for Polyhydroxy Acid.

PHAs are a type of chemical exfoliant used to gently remove dead skin cells from the surface of the skin. This process helps to reveal the fresher skin underneath, leading to a smoother and more even complexion.

Understanding PHAs

According to reference information, Polyhydroxy acid is described as a gentle chemical exfoliant. This makes them suitable for many skin types, including those that may find other exfoliants too harsh.

The exfoliation process performed by PHAs helps to:

  • Remove dead skin cells
  • Improve skin texture
  • Contribute to a more even skin tone

Common Types of PHAs

Some of the most common Polyhydroxy acids found in skincare products include:

  • Gluconolactone
  • Galactosen
  • Lactobionic acid

These ingredients work by breaking down the bonds between dead skin cells, allowing them to shed more easily. Unlike some other exfoliants, PHAs have larger molecular structures, which means they penetrate the skin more slowly and superficially, resulting in less potential for irritation.
