Sunlight is vital: It lifts your mood and promotes vitamin D production. At the same time, however, it is one of the main factors for premature skin aging. Up to 80% of all visible signs of skin aging are caused by UV radiation. Good sun protection is therefore the best anti-aging care available.
UVA and UVB: What's the difference?
- UVB rays penetrate the upper layer of skin and are responsible for sunburn.
- UVA rays penetrate deeper into the skin and damage collagen. They promote wrinkle formation and hyperpigmentation, even on cloudy days or behind glass.
Chemical and mineral filters
- Mineral filters (e.g., zinc oxide, titanium dioxide) reflect sunlight like tiny mirrors. They are particularly gentle on the skin and work immediately after application.
- Chemical filters absorb the rays and convert them into heat. They usually offer higher SPF values but often need to be applied 20–30 minutes before sun exposure.
How to recognize good sun protection
A reliable product protects against both UVA and UVB radiation, is photostable, and is tailored to your skin type. Look for terms like Broad Spectrum or UVA/UVB protection.
Application tips
- Apply enough product (about a teaspoon for the face).
- Reapply after bathing or sweating.
- Supplement protection with clothing, a hat, and sunglasses.
Conclusion
Sun protection is daily skincare – not just in summer. It protects your skin from damage, maintains its elasticity, and protects it from premature aging in the long term.
