Let's quickly talk about PHA and bionic acids in skincare

I recently got enthusiastic with a new product and over exfoliated. So I lived like a batperson (a term coined by Snow) for a couple of days while my skin healed.

The less time I could be in the sun, the better. Going out in the nights and evenings gave me plenty of time to study skincare during the day.

I turned lemons into Grade A lemonade, deciding to figure out how someone with almost always sensitive skin could gently exfoliate.

If you have sensitive skin, rosacea, dermatitis or eczema, the answer to gentle exfoliation lies in PHAs and bionic acids.

What are PHAs and bionic acids?

The skincare company NeoStrata are the creators of PHAs.

Polyhydroxy Acids and bionic acids are AHAs that are gentler and more hydrating than the usual glycolic, lactic and mandelic acid. But don't get it twisted, they may be less irritating and more hydrating but are still as effective. 

They are less irritating because they have a large molecular structure that causes slower/gradual skin penetration. In skincare, the smaller (molecularly) an ingredient, the faster it can penetrate the skin and the more likely it can irritate. 

Benefits of PHAs and bionic acids

Aside from the usual benefits of regular exfoliation, here's why you may want to use PHAs and bionic acids.

  • The larger molecular structure gives less chances of irritation/stinging making them great for sensitive and dry/dehydrated skin.
  • They are more hydrating than conventional AHAs.
  • They are antioxidant and protect cells from UV damage. UV damage = inflammation, fine lines, wrinkles, uneven tone, skin cancer.
  • They preserve the skin's natural elasticity by preventing an increase in the enzyme elastase. Elastase breaks down the protein elastin. Elastin maintains skin flexibility.
  • They inhibit MMP enzymes in skin. MMP enzymes cause the skin to sag and increase naturally with age and sun exposure.

Types of PHAs and bionic acids

  • Gluconolactone/Gluconic acid 
  • Lactobionic acid 
  • Maltobionic acid

Who Can Use PHAs and bionic acids?

Anyone. Especially if you have skin that is:

  • Dry
  • Dehydrated
  • Aging or
  • Sensitive
