The BAD (British Association of Dermatologists) recommends that you should use a sunscreen that provides broad spectrum protection (against UVA and B).
- SPF (Sun Protection Factor) refers to UVB protection. The BAD advises using SPF 30 or above.
- UVA protection is indicated by either an EU standard mark (UVA in a circle) or the Boots star system – 4 or 5 stars indicates very good protection.
Water resistance is a useful addition if you are likely to be sweating as it will not run and important if you are swimming. However, it is essential to reapply after swimming or towelling as it will have washed/rubbed off.
There are many types of sunscreen in different formulations. Ultimately, you should use one that you feel comfortable applying generously – both from a cosmetic perspective and financial.
