Retinol (Vitamin A) is the gentle version of retinoid. Retinol cream is non-prescription and can be purchased over the counter. Normally skin cells contain retinoid receptors (a class of proteins) that helps to normalise specific functions. Due to age, stress and environmental pollution, these functions can become deficient. Apply retinol cream onto the skin turns retinol into its active form, retinoic acid. The retinoic acid helps to normalise the functions of the retinoid receptors by promoting skin regeneration. It can also lessen the deterioration of collagens. As results, skin texture improves, wrinkles are diminished, brown spots are less visible and pores are minimised.
