The importance of ‘beauty sleep’ is no fairytale. Night treatments are essential to a good skin care regime, as they catch cells at their most industrious. In the wee small hours of the morning (around 1-4am) when your body is catching some zzzs, your skin cells work overtime on a quest to un-do the days’ damage. Night oils and moisturisers also help better maximise cell renewal because they are charged with highly active ingredients that would feel too heavy during the day.
