Rated 5 out of 5 by from Best product yet [This review was collected as part of a promotion.] Wow I’ve used for 3 weeks I’ve gone from spotty and very oily to having to wash my face mid way through day due to oil build up and this has cleared my skin and has made it super smooth and my very large pores are visibly getting smaller ! I use this in the morning before my advanced vitamin c serum them sunscreen then at night before my advanced peptides cream. I adore medik8 but this is a game changer !!
