Glamour: Do We Need SPF 100 Sunscreen?

glamour magazineGlamour magazine explores whether very high factor sunscreen such as SPF 100 is beneficial in the UK with input from skin experts including Dr Ross Perry. 

It used to be the case that SPF 25 was considered high, now 30 is considered quite normal and many people reach for SPF 50. Is SPF 100 about to set the bar higher?

Experts believe that it is simply not necessary for most people.

Dr Ross Perry, Founder and Medical Director of Cosmedics Skin Clinics, told Glamour:

“The overall difference in UVB protection between an SPF 100 and SPF 50 is really marginal and confusing for consumers as they seem to think it offers double the protection which is in fact not true.”

He points out that SPF 50 is very nearly as good in terms of the amount of UVB blocked:

“Properly applied SPF 50 sunscreen blocks 98% of UVB rays.”

By comparison, SPF 100 blocks very slightly more, around 99%, while SPF 30 blocks less, around 97% of UVB. However, in real terms, experts say that it would be very unusual for anyone to stay out longer than a SPF50 would protect against – plus even SPF 100 needs regular reapplication in order to maintain the benefits.

Dr Perry concluded with a reminder that the important thing is to ensure that sun protection is properly applied – which means putting enough sunscreen on, spreading it evenly and thoroughly and reapplying regularly, especially after swimming or sweating:

“When used correctly, sunscreen with SPF values in the range of 30 to 50 will offer adequate sunburn protection, even for people with pale skin and this should still be applied frequently.”
