Polyhydroxy acids (PHAs) belong to the family of chemical exfoliants and are known for their gentle yet effective exfoliating properties. Unlike AHAs and BHAs, PHAs have larger molecular sizes, which makes them less likely to cause irritation, making them suitable for sensitive skin. Their exfoliating action helps to remove dead skin cells, revealing smoother and more radiant skin.
Additionally, PHAs have hydrating properties, allowing them to attract and retain moisture, making them suitable for individuals with dry or dehydrated skin. This dual action of exfoliation and hydration makes PHAs an excellent choice for improving overall skin texture and tone.
When incorporated into a skincare routine, PHAs can help to promote cell turnover, enhance the skin's natural barrier function, and reduce the appearance of fine lines and wrinkles. They are often found in products such as exfoliating toners, serums, and moisturizers.
