The main purpose of the day cream is to maintain the skin balance. Its sunscreens are designed to protect it on a superficial level, during brief exposure periods only. Furthermore, the day cream is generally applied early in the morning. However, even in the case of a regular sunscreen, it is recommended to repeat applications every two hours for adequate protection.
Applied on a regular basis fifteen minutes before exposure, a sunscreen therefore becomes essential. Even on cloudy days, 80% of the sun’s rays reach our skin… and so it becomes important to protect our skin at all times. Furthermore, for greater effectiveness, it is essential to keep all solar products away from sources of heat or humidity, and to change them every year.
