The Inkey List Retinol Serum - 30ml

DirectionsUse in the PM after cleansing and toning and before other serums. Apply a pea sized amount to the fingers and gently tap into the skin. Advice and WarningsAvoid the immediate eye area. May increase sun sensitivity, always use a broad-spectrum sunscreen during the day. Whilst THE INKEY LIST Retinol has a low irritation formula, for some people redness and flakiness may occur at the beginning of use due to the increase in cell turnover. When first introducing Retinol, you may wish to use a few times per week and gradually increase to every evening.External use only.Tips from THE INKEY LIST When using with other productsVitamin C - we do 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, we would recommend using this in the AM as it has antioxidant properties this is when you will get the most out of the product.AHA's (Glycolic, Alpha Hydroxy, Lactic Acid) - if you are also using an AHA product in your evening routine and want to add a Retinol we suggest using building up to using your Retinol nightly and 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 we would recommend waiting around 20 minutes before applying your Retinol and be careful of overuse as both increase skin renewal and may cause sensitivity.
