What is retinol?
Retinol is a derivative of vitamin A and has long been touted the holy grail of anti-ageing. Several studies have shown that using the ingredient topically can reduce the appearance of lines and wrinkles, pigmentation and acne.
What is the difference between a retinol and a retinoid?
Vitamin A comes in different forms, including retinols and retinoids, which is where it gets confusing for most of us. Essentially, for your skin to process vitamin A it needs to be converted into retinoic acid. Retinoids need fewer conversions and are, therefore, the strongest derivative of vitamin A. Only available via prescription, retinoids are most commonly used to treat acne with GPs regularly prescribing tretinoin to help alleviate problem skin.
