Protection

Sunscreen (SPF)

What it is

Broad-spectrum filters (mineral and/or chemical) that reduce UV exposure; SPF 30+ daily is standard.

What it does

Reduces UV damage, supports even tone over time, and protects the results of brightening/anti-aging actives.

Where it appears

Morning, every day; mineral (zinc/titanium) for sensitive/reactive skin; reapply outdoors.

Who may benefit

Everyone, every morning — especially with any active or acid use.

Considerations

Mineral filters suit sensitive, reactive, or post-treatment skin. Reapply for outdoor exposure.

Common misconceptions

Indoor days and cloudy days still warrant SPF. Higher SPF is not a reason to apply less.

Interactions

Always the last step in a morning routine; the non-negotiable with any acid or retinoid use.

How Willow talks about it

Frame SPF as the foundation every routine rests on — the single highest-impact daily habit.
