This fast-acting multi-retinoid serum visibly reduces the 4 signs of skin ageing in just 2 weeks*. Gentle enough for nightly use, this high-dose retinol serum features a 3.5% Retinoid Complex + soothing Squalane to minimise the appearance of pores, smooth texture for softer skin, even tone, and reverse the look of wrinkles. Use 2 times a week, a few days apart, for the first 2 weeks, applying only at night. Increase to alternate nights for another 2 weeks, building to nightly use. If you have been using a retinoid product comfortably, you may introduce it nightly straight away. During the day, always use SPF to help protect your skin against UV exposure. This product contains retinol, a form of Vitamin A. Suitable for oily, combination and normal skin types. Can be applied on both face and neck. Avoid the eye area. Temporary redness, flakiness, peeling and sensitivity may occur. These reactions are normal and will fade over time. Use sunscreen during the day.
