Why is PHA better than AHA and BHA?

by Rashi Bahel Mehra |

What's the deal with Chemical Exfoliation?

We've been obsessed with finding out the latest skincare trends during the last few years. We've tried everything from guasha to using a gold facial mask, and now that it's 2022, we've found the latest trend that is all the rage: Chemical Exfoliation.

But with so many options out there—AHAs (glycolic and lactic acids), BHAs (salicylic acid), PHAs (Lactobionic acid)-it's easy to feel a little lost when reading labels. And even though the words "acids" and "acidic" might sound scary at first, we promise we've got your back. That's why we're here to share everything you need to know about Poly Hydroxy Acid, also known as PHA so that you can feel confident shopping for products containing this superstar ingredient.

PHA is a relatively new arrival in the world of acids but has already earned its place among the heavy hitters thanks to its ability to act as a jack-of-all-trades for both sensitive skin and those with pigmentation concerns. Its exfoliating properties help get rid of dead skin cells while also helping preserve your skin's natural moisture barrier and keeping irritation at bay.

What Is PHA?

PHAs are the newest class of exfoliating acids (such as gluconolactone and lactobionic acid) that work to gently removes dead skin cells and help keep skin hydrated. Because they are a larger molecule than other types of acids found in skincare products, PHAs don't penetrate as deeply into the skin. This means they're great for sensitive skin.

PHAs, Poly-hydroxy acids fall under the AHA family (Next-generation AHAs),but it is different from AHAs because they have a larger molecular size that does not causes irritation and is better for sensitive skin. The two most considerable benefits of using PHAs are that they are chemical exfoliants and humectants.

What Does PHA Do for Your Skin?

The benefits of incorporating PHA into your routine are similar to those of AHAs: exfoliation and Hydration. PHAs work by gently dissolving dead skin cells, making them ideal for sensitive skin types who may experience redness or irritation with other active ingredients. Unlike other exfoliants that strip the skin's surface of its natural oils and moisture, PHAs help boost hydration, replenish moisture and improve texture and tone, bringing dull skin back to life and keeping it looking more youthful by boosting collagen synthesis. PHA has excellent antioxidant properties, which help reverse UV Damage and ensure the skin barriers aren't disrupted regularly.
