Sleep and Skin

What it is

The link between sleep and skin health is an important one. During sleep, the skin undergoes a natural repair process, producing collagen and healing daily damage. Poor sleep disrupts this cycle, leading to dark circles, dullness and fine lines.

How it works in skincare

Ensuring 7–9 hours of quality sleep allows the skin to rejuvenate and enhances the effectiveness of night time skincare products, such as retinoids and hydrating serums. Think of sleep as your body’s most natural skincare tool.
