While AHA and BHA acids are the most common chemical exfoliants used in most beauty products, it can trigger a host of issues for sensitive skin.Redness, flaky skin and dryness are some of the problems these acids can cause. However, there is a solution. PHAs are a better alternative for sensitive skin because it is gentler. Here is a complete guide to the best exfoliating ingredient for this type of skin.

Polyhydroxy acids (PHA) are the second generation of alpha hydroxy acids (AHAs). The most common PHAs in beauty products are gluconolactone, galactose, and lactobionic acids. You'll find these names in the ingredient list. "This may improve clogged pores and breakouts, as well as the appearance of fine lines," Ava Shamban, MD, a Beverly Hills dermatologist told a news portal.

PHAs are a much bigger size compared to AHAs and BHAs. This allows them to only exfoliate the skin's outer layers. "BHAs really dive deeper into the skin, dissolving sebum and dead skin cells down in the pores, so they are often more suitable for oily skin and keeping acne at bay," Ava Shamban, MD, a Beverly Hills dermatologist told a news portal. PHAs work best if your skin is in need of hydration or to tackle signs of ageing. "These acids are humectant, so they have the ability to support moisture retention in the extracellular matrix, giving a firmer, plumper appearance to the skin," Shamban explained.

PHA products are safe for people with roseaca or skin issues like eczema. Another reason to switch to PHA is that products that contain it can be used in the day. Experts recommend applying AHAs and BHAs products only at night. However, you don't want to stop wearing sunscreen when you have PHA-infused products on.

You incorporate PHA acids into your skincare routine in various ways. This ingredient can be found in a range of products from masks to moisturizers.Glow Recipe's Avocado Melt Sleeping Mask is a popular product that contains PHA. Another option is Zelens PHA+ Bio-Peel Resurfacing Facial Pads. You can use the ingredient daily. Give it time to get the best results.
