Rated 5 out of 5 by from Noticeable improvements [This review was collected as part of a promotion.] I've just finished my second bottle of C-Tera. It's a beautiful addition to my Medik8 skincare routine and I've noticed wonderful results. The texture is just right for my combination skin, offering me incredible softness and reduced ageing spots. This bottle lasts me about 6 months which is great value for money as it is good potency.
