This skinSense Duo is made up of the skinSense Retinol Serum 30ml and the skinSense Retinol Eye Concentrate 15ml. skinSense Retinol Serum 30ml Formulated with a highly active, double encapsulation of pure Retinol, this concentrated serum is the perfect match for a mature skin which is beginning to show the tell-tale signs of ageing. If you’re finding that fine lines and wrinkles have taken up residence and uneven skin tone is making you camera shy, turn to this 0.3% concentration of active Retinol in a long-lasting Lamellar formulation. Retinol (also known as Vitamin A) is an ingredient which stimulates the skin into promoting new cell renewal and strengthens collagen production; restoring the skin's youthful bounciness. RETINOL: An active concentration of 0.3% provides a powerful but protected dose of active Retinol into the skin - the perfect dose for both those who are new to Retinol products, as well as veterans of hard-hitting skincare ingredients looking for an every-day product. By stimulating new cell turnover, discolouration and pigmentation fades and skin is left feeling smoother and more supple. LAMELLAR: The skinSense Retinol Serum is not only effective for its active ingredients, but is formulated with a ground breaking Lamellar Structure technology. Lamellar structures form an invisible film around the active ingredients and ensure an efficient delivery into the skin's system - locking in those anti-ageing benefits and prolonging the presence of Retinol in the skin throughout the day and night. Retinol is a highly active, powerful ingredient. With this in mind it’s important to make sure that sunscreen is applied after application, if exposed to the sunlight directly after use. skinSense Retinol Eye Concentrate 15ml A luxurious elixir to smooth and soften the appearance of the delicate eye area.
