The Facts About SPF

The Facts About SPF with Boots Soltan, La Roche Posay and Soap & Glory

When it comes to SPF and suncream, I can be a bit obsessive over it as my skin is very fair and gets red and irritated at the thought of unprotected sun exposure! I generally apply a facial SPF every day, at the moment I'm using the last of my Soap & Glory Make Yourself Youthful Sunshield SPF50+ which is great for the face as it isn't greasy and absorbs really quickly before apply my makeup. Once I've finished that one, I'll be switching to La Roche-Posay Anthelios Ultra Light Sun Cream Fluid SPF 50+ which is another non-greasy alternative for the face.

On a day-to-day basis I don't apply suncream to the rest of my body unless it's going to be sunny or I know I'll be spending a lot of time outside. I'll change between the Boots Soltan Protect & Moisturise SPF15 and SPF30 depending on how sunny it is! I've always used Boots sun cream as I find it's the best all-rounder out there and it's a brand I can trust to stop me from getting sun burn. And now onto the facts about SPF:

What are UVA and UVB rays? 

There's two different rays from sunlight that can cause damage; long wave ultraviolet UVA and short wave ultraviolet UVB. So UVA rays can reach the dermis layer of your skin (The thickest layer of your skin) and UVB rays cause damage to the top layer of your skin, and this is generally where you get sun burnt from which plays a big role in the development of skin cancer. Try and pick a sun cream with both UVA and UVB protection, most do nowadays but check the bottle before!

Which SPF factor?
There's been so much debate over the difference in SPF factors and which are really best for your skin. The SPF factor is the number which determines their ability to deflect rays from sunlight, so the higher the SPF the greater percentage of rays are deflected. SPF15 deflects 93% of rays, SPF30 deflects 97% of rays and SPF50 deflects 99% of rays. 

When to apply?
As recommend by Boots Soltan products, apply 15 minutes before going into the sun then reapply when in the sun and every 1-2 hours and after swimming. If I'm just going to work, I'll only apply my facial SPF once in the morning but if I'm in the sun on holiday, I'll be following Boots Soltan's recommendations! How much to apply is another big question, Boots Soltan say 2-3 tablespoons for the whole body which is quite a lot but when you consider how much skin you need to cover, it's really needed!

Why it's important?
Sun damage is a big part of your skin ageing at a faster and quicker rate than expected, as well as sun burn or excessive sun exposure being linked to skin cancer. You may think that you only need to apply SPF in the summer months, but the sun's rays can still reach your skin during the winter and cloudy days! What's also important is that you check the expiry date or period after opening to check that your sun cream is still effective. 

There has been some debate that I read in Stylist magazine that because we're so sun conscious now that we're preventing vitamin D from developing and now have to rely on supplements to restore that vitamin in our bodies. Experts have recommended between 10-15 minutes in the sun twice a week, without sun protection, in order to encourage vitamin D production in the body. All I can say is that if you're sensible, use the correct SPF for you and apply regularly, whilst allowing vitamin D production in your body then you'll be fine. 

What's your opinion on SPF? Which sun cream products do you use?
