Most signs of skin aging aren't actually caused by time — they're caused by UV exposure. UVA and UVB rays damage your skin invisibly but constantly. That damage shows up as pigmentation, loss of elasticity, inflammation and premature wrinkles.
Wearing sunscreen daily is one of the simplest and most effective ways to keep your skin healthy and fresh for years to come.
How do sunscreens work?
Chemical sunscreens in GrailSunscreens can protect you in two different ways:
Fine mineral particles (e.g. Zinc Oxide, Titanium Dioxide) sit on top of the skin and reflect UV rays. They're gentle on sensitive skin, but they often leave a slight white cast.
These absorb UV rays and convert them into heat. Modern versions like Tinosorb S and Uvinul A Plus are photostable and well-tolerated.
What to look for in a good sunscreen
Sunscreens in Grail- SPF 30 or higher: The SPF (Sun Protection Factor) tells you how well the product protects against sunburn. SPF 30 is the recommended minimum.
- UVA + UVB protection (broad spectrum): UVA rays penetrate deeper and cause long-term damage. Look for products labeled "broad spectrum" or marked with the UVA symbol.
- Texture: The best sunscreen is one you'll actually wear every day. If your skin is oily, go for a lightweight gel or fluid. For dry skin, a more hydrating cream formula works well.
- Plays nice with makeup: If you wear foundation, make sure your sunscreen doesn't pill or flake under it.
Great ingredients to look out for
Mineral sunscreens for sensitive skin in Grail- Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) — a modern, stable filter that covers both UVA and UVB.
- Uvinul A Plus (Diethylamino Hydroxybenzoyl Hexyl Benzoate) — photostable UVA protection.
- Zinc Oxide — a natural mineral filter, especially great for sensitive skin.
- Vitamin E, Niacinamide — antioxidants that boost the sunscreen's effect.
How to add it to your routine
- Every single morning: Apply sunscreen after your moisturizer but before makeup.
- Use enough: Around a pea-sized amount or two finger-lengths for the face.
- Reapply during the day: If you're outdoors for long stretches, top it up every 2–3 hours.
