Gluconolactone: PHA is the most tolerated acid peel

Polyhydroxy acid (PHA) is an acid suitable for exfoliating the skin. Its INCI name is gluconolactone . PHA occurs naturally in our skin and is therefore very well tolerated. This makes PHA a true alternative to AHAs . They are effective yet so gentle that they can even be used on very sensitive skin or with rosacea/couperose and atopic dermatitis.

Another advantage of PHAs is that they don't make your skin more sensitive to the sun , as is the case with other acids. Of course, sun protection is still important, as always.

Gluconolactone is water-soluble and gently removes dead skin cells. PHAs may work slightly slower than AHAs, but they deliver comparable results over a longer period – and all without side effects!

Furthermore, gluconolactone moisturizes and has an antioxidant effect. And as if that weren't enough, PHAs also stimulate collagen production .

The result? Smoother and thicker skin that is more robust, has fewer wrinkles , and a strengthened skin barrier . In other words, an ideal active ingredient for healthy aging .
