Ingredients such as gluconolactone and lactobionic acid are types of polyhydroxy acids (PHAs). Made up of larger molecules than traditional AHAs, PHAs are typically gentler on the skin, causing less irritation. Unlike some AHAs which can dry out the skin, PHAs are ideal for sensitive or dry skin types.

What are the similarities and differences between AHAs and PHAs?

PHAs are similar to AHAs in that they have both been shown in clinical studies to have anti-ageing benefits when topically applied to the skin. AHAs contain only one hydroxyl group and have been known to produce stinging, burning and tingling sensations in some people. In contrast, PHAs have multiple hydroxyl groups - providing the same age defying benefits as conventional AHAs, but without the irritation. Even very sensitive skin types can tolerate PHAs, including atopic and rosacea skin. It's thought that the gentle, non-irritating action of PHAs may be partially related to a larger molecular composition than that of conventional AHAs. Larger molecules are believed to penetrate the skin at a slower rate, causing less irritation. This reduced irritation, coupled with natural antioxidant properties, gives PHAs a gentle, competitive edge over other anti-ageing treatments. 

Benefits of Polyhydroxy Acids (PHAs):

  • • Promotes cell turnover by sloughing off dead skin cells, revealing smoother, healthy new cells underneath.
  • • PHAs have humectant effects that allow for increased moisturisation. When skin is sufficiently moisturised, it looks smoother and healthier.
  • • Enhancing skin smoothness and elasticity.
  • • Antioxidant effects. Gluconolactone is an antioxidant known for its free radical-fighting ability, protecting skin from harmful UV exposure. 
  • • Increased skin barrier function. Our skin barrier, or stratum corneum, plays a vital role in keeping out irritating chemicals and substances. 
  • • Improving skin clarity and brightness; reducing the appearance of fine lines, wrinkles, and pore size.
  • • Reduce flare-ups in inflammatory conditions. PHA products can lower inflammatory episodes of acne, rosacea, dermatitis, psoriasis and melasma.
