SPF in winter — do you still need it?

What changes in winter

UVB drops, but UVA — the ageing and pigment-driving rays — stays fairly constant. Windows filter UVB but not all UVA, so a bright desk seat still exposes you.

Snow can reflect up to most of UV, so skiing days need more diligence.

Keep it practical

Choose a moisturizing SPF that doubles as winter hydration. Apply a nickel-sized amount to face and neck and skip the heavy layering when you stay indoors.

If wearing makeup, use an SPF primer or a powder for top-ups.

When you can relax

On very dark days spent entirely indoors away from windows, risk is minimal, but habit wins over case-by-case decisions.

Tracking pigment and texture with scans makes the payoff visible.

Situations where winter SPF matters most

Skiing, driving for long periods, window-side desks and high-altitude travel all raise exposure. Reapply on the slopes every two hours, and do not forget ears and the back of the neck.

If you wear a moisturizer with SPF, check it is broad-spectrum and apply enough of it; a thin layer rarely reaches the label's protection.

Myth, reality and when to pause

Myth: Cold weather means no UV damage.

Reality: UV levels drop but do not vanish, and snow reflects extra light. Sunscreen remains a good habit.
