What does 'broad spectrum' mean?
There are two types of UV light that can be harmful to your skin - UVA and UVB.  UVA rays can prematurely age your skin, causing wrinkling and age spots. UVB rays can cause burning.  A broad-spectrum sunscreen protects you from both.
How much sunscreen should I apply?
For your face and neckwe recommend around ¼ teaspoon or the size of a coin.   To cover your entire body you need to apply 1oz/30ml which is the size of a shot glass or golf ball.  Remember, you can never have too much!
How often should I re-apply?
Every 2 hours or more frequently if you have been swimming, sweating or have towel dried.
What’s the difference between Chemical and Physical sunscreen?
Good question!  Please click here (link to Chemical v’s Mineral page) to read all about it.
Sunscreen before or after moisturiser?
You should apply your mineral sunscreen after your moisturiser. It should be the last step in your skincare routine, just before you put your makeup on (if applicable!). 
Is the SPF in make-up or a moisturiser enough protection?
Whilst either is certainly better than no protection, it doesn’t offer enough of a protection and one generally will not apply as much product as is required.   Alongside, the SPF’s added to make-up or moisturisers may not give broad spectrum cover.
P.S.  Don’t forget these commonly missed spots when applying your lotion…!

The most frequently neglected areas to apply sun protection and those often burnt are the feet, back of the knees, tops of your ears, hairline and top of your head/scalp.
