Polyhydroxy acids (PHAs)
Polyhydroxy acids (PHAs), such as gluconolactone and lactobionic acid, are very similar to Alpha Hydroxy acids (AHA’s) for it’s anti-aging effects to the skin (exfoliation & hydration). They are highly moisturising exfoliants and are typically gentler on the skin & less irritating,so ideal for sensitive or dry skin types.
The significant difference between PHA’s and AHA’s is that Alpha hydroxy is a single strand molecule allowing for quick penetration into the skin.
Poly hydroxy is a multiple strand molecule due to the larger size skin penetration is slower, gentler absorption rate, reducing any side effects such as stinging or irritation. For this reason, PHAs offer a distinct advantage over conventional AHAs (glycolic acid and lactic acid) when used on sensitive skin, such as rosacea, atopic dermatitis, psoriasis, ichthyosis, keratosis pilaris and eczema.
In addition to exfoliating and hydrating benefits, PHA offers antioxidant properties to block oxygen free-radical induced tissue damage, so therefore preventing photoaging and no increase in sun sensitivity.
