PA++, SPF50, mineral or chemical filters — everything you need to know about sun protection.
Understanding SPF and PA
SPF measures protection against UVB (responsible for sunburns). SPF30 blocks ~97%, SPF50 ~98%.
PA measures protection against UVA (responsible for skin ageing). The more + symbols, the better. PA++++ is the maximum.
80% of visible skin ageing is caused by UV. Daily SPF is the best anti-wrinkle treatment that exists.
Mineral or chemical?
Mineral (zinc, titanium): sits on the surface, works immediately, but can leave a white cast.
Chemical: absorbs into the skin, invisible, but requires 15-20 minutes of waiting before sun exposure.
The Laneige base with built-in SPF
Laneige's Skin Veil Base EX combines a makeup base with SPF28 PA++. Practical for everyday wear.
How to apply it properly
As the last skincare step, before makeup. Generous amount (~1/2 teaspoon for the face). Reapply every 2 hours during prolonged exposure.
