The french secret to flawless skin is: RE APPLY SUNSCREEN
- If it takes you 10 minutes to get burn, a SPF 30 will protect you 10*30 = 300 minutes i.e. 5 hours
- Their effect often last less because we don't apply enough or wipe some off.
- The ideal sunscreen blends protection from UVA (aging), UVB (burning), Infra red (rosacea) and Blue light (melasma)
