SPF is the single most impactful thing you can do for your skin. Not retinol, not vitamin C, not any expensive serum — just daily sun protection. UV damage is responsible for 80-90% of visible skin ageing, and it accumulates year-round, every day, even in the UK’s grey skies.
The reason most people skip SPF isn’t laziness — it’s that traditional sunscreens feel thick, leave a white cast, and sit badly under makeup. These SPF moisturisers solve every one of those problems.
What SPF Factor Do You Actually Need?
SPF 30 blocks approximately 97% of UVB rays; SPF 50 blocks 98%. For daily use, SPF 30 is sufficient. For extended outdoor exposure, go SPF 50. Don’t skip SPF because you can’t find 50 — an SPF 30 applied consistently is infinitely better than SPF 50 used occasionally.

SPF Mistakes People Make (That Age Skin Faster)
- Not applying enough: You need about half a teaspoon for the face alone to achieve the stated SPF
- Skipping cloudy days: Up to 80% of UV rays penetrate cloud cover
- Relying on SPF in foundation: The coverage is too thin to provide meaningful protection
- Applying once and forgetting: Reapply every 2 hours if you’re outdoors; once is enough for indoor days
My Verdict
Use Altruist SPF 50 for everyday use — it costs less than a cup of coffee for a month’s supply. Upgrade to La Roche-Posay Anthelios for special occasions or if you spend significant time outdoors. Either way, use SPF every single day. No exceptions.
Frequently Asked Questions
Can I use SPF instead of moisturiser?
Yes, if your SPF moisturiser provides adequate hydration. Products like No7 Protect & Perfect combine both steps effectively.
Does SPF prevent tanning?
It reduces tanning by blocking UV rays, but doesn’t eliminate it entirely. SPF is primarily about protecting skin health and preventing long-term damage and ageing, not cosmetic appearance.
