It's time to talk about something that almost everyone can use without being worried about breaking out. AHAs and BHAs are fantastic chemical exfoliants but we've heard way too many cases of people breaking out or purging periods being too long. Fear no more ladies for its time to welcome PHAs into our lives. 

So, what are they you ask? PHA stands for polyhydroxy-acid and they're very similar to AHAs. In fact, a lot of people call them the second generation AHAs. They work in a similar fashion to remove dead skin cells, hence evening out your skin tone BUT they're much milder and the best part? PHAs also attract water molecules, which means that they leave your skin moisturized after gentle exfoliation! Who would've thunk? 

Remember when we listed the most popular kinds of AHAs and BHAs to look for in your product's ingredients list? Well, here are the ones for PHAs:

  • Gluconolactone - this little piggy is an antioxidant and has anti-inflammatory properties. It's soothing and nourishing your skin in conjunction with its AHA styled properties.
  • Galactose - this little piggy is a sugar utilized in collagen synthesis, and cell migration, which has the potential to enhance wound healing.
  • Lactobionic Acid - this little piggy is derived from cow's milk and is a humectant (which means that it attracts and retains water aka moisture), its an antioxidant and generally is a soothing ninja.

Before we talk a little more in depth about the effects of PHAs, lets discuss something called glycation. Glycation is a natural chemical process, which weakens your skin's collagen and elastin. Result? Dullness, wrinkles and sagginess. It's something thats inevitable and one way to control it or slow it down is to consume less sugar in your diet. If you read back to some of the effects PHAs have listed above, you'll notice words like 'antioxidants, anti-inflammatory, soothing, nourishing, wound healing, humectant' etc. The bottom line is that PHAs are seriously rich in these properties and they accelerate epidermal growth and repair so they're a great way to slow down the process of glycation. 

Another really cool thing about PHAs is how mild they are. We're pretty sure you've heard about your skin's sensitivity to the Sun after using an AHA. Well, with PHAs you actually end up becoming more tolerant so your skin doesn't become more sensitive to the Sun at all. So all you ladies and gentlemen who are a little apprehensive about diving into chemical exfoliation, this is a great way to start. Something mild, moisturizing, soothing and all kinds of goodness would definitely be the way to go. 

We have two new products in our collection which would be pretty awesome:
