Pestle & Mortar Superstar Retinoid Night Oil fights visible signs of aging, reduces the appearance of fine lines and wrinkles, reduces pore size, and evens skin texture and tone while you sleep. It contains two kinds of Retinoid, specially blended to be extra effective but non-irritating. Hydroxypinacolone Retinoate in particular represents a new generation of Retinoid. It helps reverse signs of ageing, smoothes lines and wrinkles, and boosts collagen production. It stimulates cell growth and cell turnover , restoring suppleness and hydration to the skin. Retinoids and Retinol are both forms of Vitamin A, known for its effectiveness in rejuvenating skin. Cold pressed oils including Rosehip Oil, Jojoba Oil, Carrot Seed Oil and more are packed with powerful antioxidants and Vitamins A, E and C to combat free radical damage, stimulate cell growth and repair damaged skin, resulting in a smoother, revitalised complexion. Pestle & Mortar Superstar Retinoid Night Oil is suitable for all skin types, even oily and sensitive. As this product uses especially effective forms of Retinoid rather than Retinol, the risk or irritation is very low. However, if you do notice bothersome flaking skin or irritation, discontinue use.
