What are active ingredients? Active ingredients in skincare products include Alphahydroxy acids, Polyhydroxy acids, Retinol, Vitamin C, Kojic Acid and Arbutin. They are found in varying concentrations in different grades of skincare products. The concentrations of these ingredients are higher in a special category of skincare products called cosmeceuticals. These cosmeceutical ranges are typically only available in Dermatologist’s or Doctor’s rooms. The majority of the products sold on Skinsmart fall into this category of cosmeceutical products with high concentrations of active ingredients.These active ingredient products need careful introduction to your skin, as they may cause irritation and sun sensitivity.The high concentration of active ingredients in these products also mean that they have better results in targeting your skin concern, particularly anti-ageing.
