Can I use the same product both day and night? Quickshop 1. Day cream for day-long protection Day and night creams... are like night and day. During the day, skin is subjected to a number of harsh external factors, whether it is oily, combination or dry. Among them: pollution, UV rays, temperature changes and stress. Day creams are therefore designed to protect and hydrate skin. They can also have targeted effects on skin ageing, excess sebum production and dehydration. If you have oily skin, choose a lightweight, fluid texture. If you have dry skin, try something richer and creamier. 2. Night cream for regeneration Come night, skin gets some well-deserved rest and regenerates. This is why sleep is so essential for skin that glows! Night creams draw on this down-time to boost regeneration, while supplementing your day cream. Skin is refreshed and revitalised upon waking. 3. Clarins day & night duos to cover every base At Clarins, there's a day/night duo to keep your skin happy.
