Do You Still Need SPF in Winter? Yes – Even on Cloudy Days

Overcast winter landscape showing cloudy skies and diffused daylight.

One of the most common skincare myths I hear is: “I don’t need SPF in winter.” In reality, winter and cloudy days are when many people unknowingly accumulate long-term skin damage.

Important fact: UVA rays — the main cause of premature ageing — pass through clouds and glass and are present all year round.

Why Winter Sun Still Affects Your Skin

  • UVA rays remain consistent throughout the year
  • Clouds do not block UVA radiation
  • Windows offer little protection against UVA
  • Cold weather can weaken the skin barrier

This means your skin is exposed even on grey, rainy Irish days — especially if you spend time near windows, drive regularly, or use active skincare products.

Who Especially Needs Daily SPF in Winter?

  • Sensitive or reactive skin
  • Rosacea or redness-prone skin
  • Pigmentation or uneven tone
  • Mature skin
  • Post-treatment skin

If your skin ever feels more sensitive or flushed in winter, skipping SPF may be part of the problem.

Choosing the Right SPF for Winter

  • Lightweight texture that layers well under moisturiser
  • Broad-spectrum UVA/UVB protection
  • Suitable for sensitive or dry winter skin
  • Comfortable enough for daily use
Professional tip: If your SPF feels heavy or irritating, it’s likely not the right formula for your skin — not a reason to skip protection altogether.

SPF as Part of Long-Term Skin Health

Daily SPF is one of the most effective anti-ageing and skin-protective steps you can take. It supports all other treatments and helps maintain results over time.
