SPF 50 That Sweats Off by 10am Is Not Protection
8 September 2026 10 min read 2 views 0
South African summer UV plus sweat, sport and swimming means the number on the bottle only counts if a film is still on your skin. Reapply.
Key takeaways
- Water resistance is a lab claim; sweat and towels still remove film.
- Most people under-apply; two finger lengths for the face.
- Tinted SPF helps melanin-rich skin against visible light.
- Pharmacy SPF you reapply beats prestige SPF in the bag.
