List of SPF and % of sun they block out?

[nappyaddict]

I know SPF 15 blocks out 94% and SPF 30 blocks out 97%. Is there a list where I can find the SPFs that fall in between these?

The lady in boots told me the other day that its not just the SPF you have to worry about its the UVA stars too. I was looking at a moisturiser but it was only SPF 15 and I normally wear much higher under my makeup. Apparently UVA is the aging part and UVB is the burning. All quite complicated isn't it. I've always stuck with boots soltan for the body and la Roche posay or avene for the face as its nice under makeup.

Yes I have heard that you should look for a 4 star UVA rating or something that contains zinc oxide for good UVA protection.

nivea normally only has 3 star protection so we avoid it. I have used own brand supermarket 5 star stuff plus ambre solaire, soltan, etc with no issues.

That's right miche, I worked at boots and did the sun shop for a couple years. A high SPF will prevent you from burning, A high UVA rating (5 stars) will help prevent long term skin damage.
An SPF helps you work out how much longer you can stay in the sun without burning. The percentage coverage varies so much, depending on skin type, how much is applied, how long it's been on for etc.

We have some Aldi stuff which is 5 star - so the cheap stuff isn't always the worst and if Nivea is only 3 star then the expensive stuff isn't always the best!! Apparently UVA rays also cause sun burn?

Malibu Once Daily and Calypso Once is also only 3 star.
