Whereas many anti-ageing ingredients merely help to prevent the visible signs of ageing, retinols are renowned for their unique ability to visibly reverse the appearance of fine lines, wrinkles and dark spots to promote a more even, and more youthful- looking complexion. The OSKIA Retinoid Sleep Serum Level 1 is a gentle, yet highly effective treatment boasting the brand’s advanced Super-Nutrient Retinoid Complex, featuring Retinoid, Vitamin C & E and Pro-Vitamin D3. This ultra-brightening and smoothing treatment helps to restore a natural glow to mature or congested skin types, with a high concentration of cellular nutrients. Botanical actives and anti-oxidants help to reinforce your skin’s natural defences against the ageing and dulling effects of environmental aggressors such as pollution, promoting a plump, firmed and youthful appearance. This super-charged serum is perfect for those looking to incorporate retinols into their skincare regime to promote a smooth, firm and radiant visage. Once your skin has become accustomed to the gentle yet effective benefits of this serum, you can move on to the stronger Level 2 serum with a higher concentration of retinol for maximum efficacy.
