The creamy formula with retinol* penetrates deep into the skin, accelerates cell renewal and visibly reduces fine lines and wrinkles. Skin tone looks more even and radiant and pores appear minimized. Provides instant and long-lasting hydration that soothes the skin and balances dryness. *Retinol tolerance varies from person to person. Retinol is an extremely effective and powerful anti-aging ingredient. Mild redness, a warm, tingling sensation or skin flaking may occur at the beginning and are normal and temporary signs that the product is working. - If you experience increased side effects while using Clinique Smart Night Clinical MD Multi-Dimensional Repair Treatment Retinol, you should reduce application to every other night until the skin has adjusted. This adjustment period can take up to 4 weeks. - First-time users and those with very dry skin should use the product every other night for two weeks to give the skin a chance to get used to it. For more intensive care, use a mild cleanser and follow with a moisturizer. - During use, you should greatly reduce the amount of time you expose your skin to the sun. Be sure to apply a sunscreen with SPF15 or higher during the day while using the product and for one week after you stop using it. Be aware that extreme weather conditions such as wind or cold can irritate the skin more, so take the appropriate precautions to protect your face.
