Edit UVA and UVB

<p><strong>So if <a title="sunscreen information" href="/Treatment/sunscreen" target="_blank" rel="noopener">sunscreen</a> is important for exposed skin, what type/strength should we be wearing?</strong></p> <p>It is a minefield with SPF now added to BB creams, moisturisers and foundation! Firstly, lets look at SPF ratings: The advice from the National Institute of Clinical Excellence (NICE) is that factor 15 can provide adequate protection if applied correctly. When sunscreens are tested, they are usually applied at a thickness of 2mg of product for each 2cm2 of skin!</p> <p>This would mean ‘caking’ on the foundation to get the factor 15 rating on the tube! Going further, i.e. wearing at least a SPF 30 or above, does go some way to counteracting the problem of coverage that is too thin.</p> <p>Also, look for a ‘broad spectrum’ SPF or for the UVA sign in a ring/with four stars. These sunscreens provide protection across the spectrum of wavelengths.</p>
