PHA

Polyhydroxy acids (PHAs) are a gentle class of exfoliating acids that provide mild exfoliation, deep hydration and antioxidant benefits while being well-tolerated by sensitive and reactive skin. They offer similar benefits to AHAs but with less irritation, making them suitable for all skin types, including sensitive and rosacea-prone skin. Key benefits are:

• Gentle Exfoliation: Helps remove dead skin cells to promote a smoother, more radiant skin appearance while minimizing irritation.
• Hydration Boost: Acts as a humectant, drawing moisture into the skin to enhance hydration and barrier function.
• Antioxidant Protection: Helps combat free radicals and oxidative stress, supporting skin’s natural repair processes.

Gluconolactone, a PHA used in Eucerin products, provides multi-functional benefits by exfoliating, hydrating and protecting the skin, making it a key ingredient for improving texture, tone and overall skin health.
