The BB cream contains lots of anti-oxidants and and SPF 15. It leaves skin with a dewy finish, so if you prefer something matte, you'll need to powder over the top. It's also a very light coverage, so not something if you prefer a full coverage foundation.
I think this will be a great option for most people for the summer months when you want something a bit lighter on your skin, but still enough to help even out skintone.
REN's BB cream retails at £26 for 50ml and can be found on REN counters or online on their website.
