Sunscreen

The non-negotiable

What it does

Reduces UV damage, tanning, persistent marks and photo-ageing. It protects progress from every other step.

Who it suits

Everyone, every morning, including cloudy days and indoor days with meaningful window exposure.

How to start

Use two finger-lengths for face and neck. Reapply during extended outdoor exposure, sweating or swimming.

What it pairs with

Everything. Sunscreen is the final morning skincare step.

What to avoid

Do not rely on makeup SPF alone. A perfect formula you will not wear is less useful than a comfortable one.

What to expect

Prevention is the result. Existing marks still need time, but new darkening is reduced.

Evidence, honestly

Extensive high-quality evidence supports broad-spectrum sun protection.
