I recommend;

Salicylic and mandelic acid dissolve impurities & oil to decongest and tighten pores, whilst natural jojoba grains gently exfoliate away dead skin cells.
Pores are left virtually undetectable and skin feels soft, smooth and supple.
DIANE'S TIP: Use 2/3 times a week after cleansing
Massage into damp skin for 5 mins - can be left on skin for a further 5-10 mins where you have lots of blackheads, blocked pores, bumps under the skin or ingrown hairs
Don't exfoliate everyday as this strips away the healthy oils.

How C-Tetra Vitamin C Radiance Cream works on your skin
Your skin needs antioxidants to defend it against free radical damage from the environment. When environmental free radicals outweigh the antioxidants present in your skin from diet and nutrtion the skin can no longer protect itself. Free radicals create irreparable damage to our cells which leads to visible premature ageing of the skin - discolouration, sagging, wrinkles & malignant cell changes
C-Tetra Cream contains tetrahexyldecyl ascorbate, a stable form of vitamin C that boosts the antioxidant defence levels in the skin. Vitamin C stimulates collagen production to reduce the appearance of fine lines and wrinkles, leaving the complexion plump, radiant and youthful. As a lipid-soluble form of vitamin C, it is able to penetrate the skin’s defensive lipid barrier with ease, delivering benefits deep within the skin.
Vitamin C and vitamin E work together synergistically as 'network antioxidants', boosting the cream’s overall antioxidant effect.
C-Tetra Cream also harnesses superior hydration power by combining hyaluronic acid and glycerin with Medik8’s signature Moisture Magnets™. These draw water from the atmosphere and from lower layers of the skin to leave the complexion supple and moisturised.
Ingredients
Tetrahexyldecyl Ascorbate
A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, while stimulating collagen production for a youthful looking.
Vitamin E
