The INKEY List Retinol Serum helps to stimulate the renewal processes in the skin resulting in brighter, smoother skin. A derivative of Vitamin A, Retinol helps to promote skin renewal and enhance collagen production. As we get older the rate at which our skin renews itself slows. Retinol works beneath the skin surface at a cellular level to promote cell renewal and repair processes so that newer cells reach the surface quicker. Stimulating these renewal processes in the skin makes Retinol a powerful ingredient for reversing signs of ageing as well as improving overall skin clarity for a healthy-looking complexion. Using Retinol can aid with a number of skin concerns such as reducing the appearance of fine lines, wrinkles, uneven skin tone and pigmentation issues making it an all round must have for healthy looking skin. Retinol acts to: - Target wrinkles - Reduce the appearance of wrinkles - Reduce fine lines - Even skin tone INKEY Info: - Slow release formula for low irritating, effective active delivery - 1% RetiStar stabilised Retinol - 0.5% Granactive Retinoid - Squalane for hydration and soothing - Suitable for all skin types Retinol is the gold standard of skincare ingredients and offers a whole host of benefits. Whilst Retinol is famed for it\'s ability to fight signs of ageing, it can be benefit all ages. Starting use in the mid-twenties can have huge benefits for the skin. Retinol is often associated with irritation, flakiness and redness when first introducing the product, however new technologies now enable us to formulate Retinol products that offer maximum efficacy with minimal irritation. When using with other products: - Vitamin C INKEY does not recommend using Retinol and Vitamin C at the same time. It is best to use Retinol in the PM, so if using a Vitamin C INKEY would recommend using this in the morning. As it has antioxidant properties this is when you will get the most out of the product. - AHAs (Glycolic, Alpha Hydroxy, Lactic Acid) If you are also using an AHA in your evening routine, and want to add a Retinol, INKEY suggest building up to using your Retinol nightly and using acids weekly or if you want to use your acid more regularly alternating with Retinol. If you do wish to use both on the same day, due to PH levels INKEY would recommend waiting around 20 minutes before applying your Retinol and be careful of overuse as both increase skin renewal and may cause sensitivity. The INKEY List recommend using Retinol from age 25+, or when the first signs of ageing begin to show.
