The Japanese Sunscreen Culture (and Our Favourite SPF Picks)

If you’ve ever wondered why Japanese sunscreens are cult favourites worldwide, it’s simple: everyday sun care is part of the routine here—right alongside cleanser and moisturiser. Formulas are famously lightweight, layer beautifully under makeup, and emphasise strong UVA protection (the rays that age skin) as much as UVB (the ones that burn).

SPF vs. PA: what the labels mean in Japan

• SPF measures protection against UVB (sunburn).

• PA measures protection against UVA using the UVAPF/PPD method. In Japan, PA has four levels: PA+ (PPD 2–4), PA++ (4–8), PA+++ (8–16), and PA++++ (16+)—PA++++ is the highest grade under the Japan Cosmetic Industry Association standard. (jcia.org)

Why Japanese sunscreens feel different

• Feather-light textures: gels, watery essences, and milks absorb fast and sit smoothly under makeup.

• Everyday wearability: many double as primers or tone-up bases, so you’ll actually enjoy reapplying.

• Practical formats: mists and body gels make top-ups easy on commutes or outdoor days.

How to use (so you actually get the protection)

Apply generously to face and body and reapply every ~2 hours, especially if you’re sweating or swimming. That’s standard best practice—and we repeat it often on our socials because it matters. (Instagram)
