Introduction to Polyhydroxy Acids
Polyhydroxy acids, commonly known as PHAs, are a type of chemical exfoliant that have gained popularity in recent years for their gentle yet effective exfoliating properties. PHAs offer a milder alternative to other chemical exfoliants like alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), making them suitable for those with sensitive skin or beginners looking to incorporate chemical exfoliation into their skincare routine.
What are Polyhydroxy Acids (PHAs)?
Polyhydroxy acids are a group of organic acids that contain multiple hydroxyl (-OH) groups in their molecular structure. Unlike AHAs and BHAs, PHAs have larger molecular sizes, which means they penetrate the skin at a slower rate. This slower penetration allows for a gentler exfoliation process that is better tolerated by sensitive skin types.
History and discovery of PHAs
Polyhydroxy acids were first discovered in the 1970s by Dr. Eugene Van Scott and Dr. Ruey Yu, who were investigating the potential of certain acids to improve skin texture and reduce signs of aging. Their research led to the development of PHA compounds such as lactobionic acid and gluconolactone. Over the years, PHAs have been extensively studied and incorporated into various skincare products due to their ability to enhance the skin's appearance and improve its overall health.
Comparison to other types of chemical exfoliants
When comparing PHAs to other types of chemical exfoliants, such as AHAs and BHAs, PHAs offer several advantages:
- Their gentle nature makes them suitable for individuals with sensitive skin, as they have a reduced risk of causing irritation or redness.
- PHAs provide hydration benefits and improve the skin's moisture barrier, unlike some other exfoliants that can be drying.
- Although PHAs have a slower exfoliating action, they still effectively remove dead skin cells, revealing a smoother, brighter complexion over time.

Polyhydroxy Acids (PHAs): The Gentle Exfoliators
Polyhydroxy acids (PHAs) are a group of skincare ingredients that are gaining popularity for their ability to exfoliate the skin and promote a more youthful complexion. In this guide, we will explore how PHAs work in three key areas: mechanism of action in skin exfoliation, interaction with the skin barrier, and stimulation of collagen production.
Mechanism of Action in Skin Exfoliation
PHAs work by breaking down the bonds that hold dead skin cells together, promoting their shedding and revealing fresh, radiant skin underneath. Unlike other chemical exfoliants such as alpha-hydroxy acids (AHAs), PHAs have larger molecular structures, which means they penetrate the skin more slowly and cause less irritation. This makes PHAs an ideal choice for individuals with sensitive skin or those new to chemical exfoliation.
Interaction with the Skin Barrier
PHAs have humectant properties, meaning they attract and retain moisture. This helps to strengthen the skin barrier, improve hydration levels, and reduce transepidermal water loss. By reinforcing the skin's protective barrier, PHAs help to restore and maintain a healthy skin barrier function, leading to improved skin texture and reduced sensitivity.
Stimulation of Collagen Production
PHAs have been found to stimulate the production of collagen, a crucial protein responsible for maintaining the skin's elasticity and firmness. By encouraging collagen synthesis, PHAs help to improve skin plumpness and reduce the appearance of fine lines and wrinkles. This makes PHAs an excellent choice for individuals looking to combat signs of aging and achieve a more youthful complexion.
Incorporating PHAs into Your Skincare Routine
When incorporating PHAs into your skincare routine, it's important to start slowly and gradually increase frequency as your skin adjusts. Begin by using PHA-based products once or twice a week and monitor your skin's response. If well-tolerated, you can then increase usage to every other day or even daily.
Conclusion
Overall, Polyhydroxy acids offer a gentle yet effective approach to skin exfoliation, barrier repair, and collagen stimulation. With their unique properties and benefits, PHAs are becoming increasingly popular in the world of skincare. Give them a try and discover the transformative effects they can have on your skin.
