The product is said to boost the regenerative process in the skin, smoothing out fine lines and pumping back radiance into the skin. With 6% lactic acid the skin is repaired, while the glycol acid content boosts collagen in the skin, thickens the skin and evens out the epidermis. The slight scent means is calming, and leaves skin feeling fresh and clean before bed time! Despite its hefty price tag, the pea size amount required to cover the face at night means that a tube of the 30ml bottle will last months.
