PHA, or polyhydroxy acid, is a type of chemical exfoliant known for being much gentler than AHAs and BHAs, making it a great option for sensitive or dry skin. This mild exfoliant helps to smooth skin texture, brighten the complexion, and hydrate without causing irritation, making it a popular choice in Korean skincare.

Benefits of PHA (Polyhydroxy Acid): Works by gently exfoliating the outer layer of the skin, helping to remove dead skin cells and reveal a brighter, smoother complexion. Unlike stronger acids, PHAs have larger molecular structures, meaning they penetrate the skin more slowly, reducing the risk of irritation. PHAs are also humectants, meaning they attract moisture to the skin, making them ideal for keeping the skin hydrated and plump while exfoliating. Regular use of PHAs can improve skin texture, reduce fine lines, and provide a radiant glow without causing sensitivity.

Ingredients That Work Well with PHA (Polyhydroxy Acid): Pair well with hydrating ingredients like hyaluronic acid and glycerin, which help enhance their moisturizing effects. They also work beautifully with niacinamide, which calms the skin and strengthens the skin barrier, making this combination ideal for sensitive or reactive skin. PHAs can also be used alongside antioxidants like vitamin E to protect the skin while gently exfoliating.

Ingredients to Avoid Mixing with PHA (Polyhydroxy Acid): Are gentle and can be combined with most ingredients, but to avoid over-exfoliation, it’s best not to use them alongside strong exfoliants like AHAs, BHAs, or retinoids in the same routine. These combinations can potentially irritate the skin, especially for sensitive skin types. Instead, alternate the use of PHAs with stronger actives to maintain a balanced and healthy skincare routine.
