What is "P.H.A." and what is its utility?

Belonging to the AHA family, PHA or Polyhydroxy Acid is a gentle chemical exfoliant. It smooths and evens out the skin by getting rid of dead cells on its surface. The main difference between PHAs and AHAs is the molecule size. The question that arises is: what is the utility of PHA? Let's focus.

P.H.A., what is it?

Similar to A.H.A. and B.H.A., P.H.A. or polyhydroxy acids are chemical exfoliants. There are several types:

  • The gluconolactone or gluconic acid: this active ingredient is naturally present in skin cells;

  • The galactose : naturally present in the deep layers of the skin, this active ingredient influences the production of collagen;

  • Thelactobionic acid : this active ingredient derived from lactose has soothing and moisturizing properties.

P.H.A.s are suitable for all skin types, especially sensitive skin. They serve to exfoliate the upper layer of the skin, without increasing its sensitivity to the sun. These are gentle ingredients due to the large size of their molecules. Therefore, they take time to penetrate the skin. They primarily act on the outer layers of the skin and tend to be less irritating.

P.H.A.s, such as lactobionic acid and gluconolactone, function similarly to A.H.A.s. Responsible for gentle skin exfoliation, P.H.A. also hydrates the skin. Additionally, it improves its texture and firmness.

P.H.A.s can be combined with other active ingredients such as vitamin C or retinol. Their side effects are minimal. Even if you have sensitive skin, applying this active ingredient is unlikely to cause tingling or irritation.

PHA, what is its usefulness?

When used regularly, P.H.A.s smooth and soften the skin. Moreover, they restore its radiance. P.H.A.s perform numerous functions:

  • They remove dead skin cells and deeply cleanse the pores;

  • They enhance the appearance of the skin;

  • They stimulate the skin renewal process;

  • They soften the skin and promote its hydration;

  • They strengthen the skin barrier.

Thanks to the size of their molecules, P.H.A.s provide gentle exfoliation and are suitable for sensitive skin. In addition to their exfoliating virtues, they possess moisturizing properties. They can be used during pregnancy. Moreover, these active ingredients are suitable for acne-prone skin as they help to even out the complexion and improve the texture of the skin.

Furthermore, P.H.A.s also have the advantage of retaining moisture. They even help to combat glycation, a process that weakens the collagen and elastin in the skin.
