Water- and silicone-free, The Ordinary€™s Retinol 1% in Squalane features highly stable retinol, an ingredient that can reduce the appearance of ageing with impressive results. A powerhouse form of vitamin A, retinol encourages cell turnover, revealing healthier, softer skin while also tackling blemishes, dark spots and defying signs of ageing €“ including softening the appearance of fine lines and wrinkles and uneven tone. Retinol can cause significant irritation, including redness and peeling, but many feel that its significant effects counterbalance this; The Ordinary recommends building your skin€™s tolerance to retinol with lower concentrations to minimise discomfort.
