What SPF should I use for daily wear vs. beach days?

Use SPF 30 for daily life — it blocks about 97% of UVB rays, is easier to find in wearable textures, and the extra 1% from SPF 50 doesn’t matter for commuting or dog walks. For beach or pool days in direct sun, grab SPF 50+ for a stronger buffer against missed spots and water resistance. Skip SPF 100 — the extra protection is negligible.
