Why Daily SPF Matters
Sun damage happens every single day, not just on holidays. Around 80–90% of visible skin ageing comes from UV light, not time or genetics. Most skin cancers are also linked to UV exposure. The damage isn’t sudden; it’s slow, silent, and builds up over years.
Everyday Exposure
- UVA rays pass through cloud, glass, and car windows.
- They make up around 95% of all UV that reaches the ground.
- Small daily bursts such as walking to work, driving, or sitting by a window quietly add up.

What That Means
- Fine lines, uneven tone, and rough texture develop after years of small, repeated exposure.
- DNA damage that leads to skin cancer also builds gradually and may not appear for decades.
