Why a Night Treatment Belongs in Your Routine

Your skin does much of its repair work while you sleep — cell turnover peaks overnight and, without sun and pollution to defend against, it's the ideal time for richer, more active treatments. That's the case for a dedicated night step.

Why night matters

• Overnight is when skin renews and repairs most actively.
• Richer treatments have hours to absorb undisturbed.
• Renewal actives that increase sun sensitivity are best used at night.

What to look for

A good overnight treatment replenishes moisture, supports renewal and helps you wake to smoother, more rested-looking skin. Copper peptides and nourishing, barrier-supporting ingredients are ideal — and a hydrating base like our Hyaluronic Acid Serum helps everything absorb.

Our overnight hero

Frequently asked questions

How often should I use an overnight mask?

It can be used nightly or a few times a week, depending on your skin's needs and the rest of your routine.

Do I still need a day moisturiser?

Yes — daytime skin needs hydration plus SPF protection, which an overnight treatment doesn't provide.
