Some say it’s better than AHA and BHA.
PHA, a.k.a. Poly Hydroxy Acid, is the new acid on the block we’re referring to! This super acid offers the same wonderful benefits as AHA (Alpha-Hydroxy Acid), minus the skin irritation associated with both AHA and BHA (Beta-Hydroxy Acid) – we’ll share more in just a bit.
The gentle giant of chemical exfoliators
So what makes PHA a better acid than AHA and BHA? PHA has a larger structure (molecular size) than its counterparts, allowing it to work its magic on just the skin’s surface levels. Its larger molecular size also slows down its rate of penetration into the skin, making the exfoliation process gentler and less sensitising. As such, this makes PHA a great chemical exfoliant for those who are prone to skin sensitivity and redness, and it’s even suitable for use while pregnant!
Why should you use PHA?
PHA is chock-full of goodness for the skin! More than just a chemical exfoliant to slough away dead skin cells to smoothen and brighten dull complexions, it also provides the following benefits for our skin.
1. Moisturising effect
As PHA is also a humectant, it is able to attract and lock in moisture. When your skin is well-hydrated, it naturally appears plumper and healthier, and fine lines will be visibly diminished too!
2. Enhances skin barrier function
PHA helps to increase skin’s resistance to external stressors by supporting the skin’s barrier function. With a healthy skin barrier, skin becomes smoother, softer and more supple.
3. Antioxidant benefits
If you don’t already know, antioxidants are great in the prevention of UV and pollution-induced free radical damage to collagen and skin cells. What this means is that you’ll also see some anti-ageing effects from using PHA!
4. Increases efficacy of subsequent products applied
As with all exfoliants, both physical and chemical, the exfoliating action of PHA will facilitate the penetration of other products applied subsequently. The effectiveness of your skincare routine will be boosted when your skin isn’t covered by a layer of dead skin cells, trust us on this.
How should you use PHA?
Increase the efficacy of your PHA product by pairing it with creams with moisture-locking ingredients such as Ceramides, Hyaluronic Acid, Glycerin and Peptides. What it’ll do is increase the humectant nature of the PHA and keep your skin well hydrated throughout the day/night. Additionally, these ingredients are great at improving skin barrier functions and will help to defend your skin from free radical damage and pollution.
When PHA is formulated in high concentrations such as in ést.lab’s all-new LumiWhite 10% PHA Resurfacing Glow Serum, it is not recommended to layer with these active ingredients:
1. Vitamin C
Due to the high 10% concentration of PHA in our serum, mixing it with Vitamin C may cause breakouts or irritation, especially for sensitive skin.
2. Retinol
The use of Retinol and PHA is a harsh combination and can cause over-sensitisation of your skin. Retinol is known for its ability in skin cell turnover, but yet it may exacerbate skin dryness, and hence is not recommended to be used with chemical exfoliants.
3. Other Acids
It is not advisable to use other chemical exfoliating products such as AHA and BHA together with PHA, especially if they are already appearing in high dosages on their own (more than 2%).
