Why should I use a separate sunblock when my moisturiser & foundation contains it?
Due to the amount of sun protection that is mixed into these products, it is not enough to provide you with all day protection. A separate sunblock (SPF30+) should be applied after your moisturiser and before your foundation to give you a good 6 hours of protection against the UVA ageing rays, UVB burning rays & UVC cancerous rays. For maximum protection a sunblock should always be applied 20 minutes before going out in the sun.
