Polyhydroxy acids (PHAs) are a new trending beauty product that claims to reduce fine wrinkles.

PHAs, according to Trusted Source, can moisturise skin and enhance skin cell regeneration, reducing the appearance of fine lines and wrinkles. They’re less irritating than similar exfoliating chemicals, especially if you have sensitive skin.
Here’s all you need to know about PHAs: how they operate, how to use them, and where to look for them.
The consequences of ageing on your skin are numerous: The epidermis (the outermost layer of the skin) thickens. The skin retains less moisture and has a lower collagen content. The DNA of cells is further harmed by exposure to the sun. These things work together to make wrinkles appear more prominent.
PHAs are a type of chemical that exfoliates the skin.
Exfoliation helps to remove dead, dull-looking cells, reveal healthy cells, minimise hyperpigmentation, and enhance skin texture by sloughing away dead, dull-looking cells.
Are PHAs superior than BHAs or AHAs for sensitive skin?
PHAs are a form of hydroxy acid (also known as a fruit acid). Alpha hydroxy acids (AHAs) and beta hydroxy acids are two other types of hydroxy acids (BHAs).
All three are used in skin care products to help reverse sun damage, reduce wrinkles, and improve skin elasticity, tone, and hydration.
PHAs, on the other hand, are less likely to irritate sensitive skin.
Acne, scars, dark spots, dryness, and wrinkles are all treated with alpha hydroxy acids (AHAs), which include glycolic acid and lactic acid.
Salicylic acid, for example, is an anti-inflammatory BHA. According to Engelman and Shainhouse, they’re frequently advised for oily or acne-prone skin.
These elements, however, aren’t for everyone.
Swelling and burning are common side effects of AHAs, and they can also make your skin more susceptible to the sun.
So now that you know the uses of PHA, go grab it!
