A separate night cream (or indeed serum) really is worthwhile. That’s because day and night skincare products have two key functions. Day products focus on protection. Night-time products focus on repair, because this is when is your skin is naturally primed for recovery and regeneration. Nights creams are restorative. They are often richer, thicker formulations packed full of ingredients such as peptides, ceramides and antioxidants that nourish and replenish your skin, in addition to hydrating and/or moisturising.
