What is the formulation of poly hydroxy acids suitable for?

Polyhydroxy acids (PHAs) are a class of exfoliants that are derived from lactose and are considered to be gentler than alpha and beta hydroxy acids. They are particularly suitable for sensitive skin due to their multifunctional properties that include exfoliation, hydration, and soothing effects.

PHAs have a larger molecular structure than other hydroxy acids, which means they do not penetrate the skin as deeply and cause less irritation, making them ideal for those with delicate or reactive skin types. They provide effective exfoliation without the aggressive peeling that can be associated with stronger acids, allowing individuals with sensitive skin to benefit from exfoliation while minimizing the risk of redness or discomfort.

Furthermore, PHAs can help to strengthen the skin's barrier function, thus enhancing its resilience over time. Because sensitive skin often struggles with inflammation and compromised barrier function, the adjusting effects of PHAs cater specifically to maintaining skin health and comfort.
