Retinoids are one of the most proven, known, effective and powerful ingredients for treating skin issues from acne to wrinkles; retinol is an over-the-counter retinoid. Using a well-formulated and stable retinol product is important to visibly reducing the appearance of fine lines, wrinkles and pores. Retinols are challenging to formulate with, as they are sensitive to light, oxygen, heavy metals and heat. As a result, retinoids must usually be manufactured under an inert gas and subsequently packed in oxygen- and light-impermeable containers. BASF’s RetiSTAR™ is a unique retinol combination that provides superior stability against the degradation of retinol and eliminates the need to manufacture products under inert conditions. RetiSTAR™ is 5% retinol combined with sodium ascorbate and tocopherol to provide a stabilized retinol that is also easy to formulate with.
