As an expert in skin health, I am constantly monitoring and compiling research on ingredients associated with ageing skin. Vitamin A (Retinol) has 40 years of study behind it, with an astounding amount of clinical data supporting its benefits in anti-ageing. Referred to in the industry as the “normalising vitamin” due to its ability to convert abnormal skin back to health, Retinol is one of the most sought-after ingredients for the treatment of both acne and ageing.
So, how does it work? Once applied to the skin, it is converted into Retinoic Acid (Tretinoin) – the same compound as the prescription drug, ‘Retin A’. The increase of Retinoic Acid signals cells to produce more collagen and less melanin whilst boosting cellular regeneration; thickening the underlying dermis and reversing the signs of ageing. Studies show that topically-applied Retinol also stimulates the synthesis of Hyaluronic Acid, which keeps the skin hydrated and plump and visibly reduces the appearance of wrinkles.
Retinoids bind to DNA in sebocytes and balance the amount of sebum (oil) they produce, inhibiting the bacteria that leads to acne.
Caution: In the early stages of treatment, alternate the days on which you use A+ until the skin has built enough tolerance to it for daily use. Because retinoids make the skin photosensitive and more susceptible to UV, I recommend using it at night.
