Antioxidant serum containing lipid vitamin C<\/h5>\n
\n

Antioxidant serum with vitamin C and vitamin E C-TETRA protects the skin against ageing and reduces visible signs of ageing such as wrinkles, fine lines, contour lines or excessive pigmentation. It also reduces skin redness, unifies skin tone and improves skin texture. It is also ideal as part of CSA’s anti-wrinkle philosophy.<\/p>\n

Antioxidation of the skin<\/h2>\n

Restore youthful radiance and fight the visible signs of ageing with C-TETRA, a lightweight serum that contains a network of antioxidants<\/a> in the form of vitamin C<\/a> and vitamin E<\/a>. Together, these protect the skin against free radicals<\/a>, particles with high energy potential that damage collagen<\/a>, the skin’s natural building block. As a result, skin ageing and its visible manifestations then occur.<\/p>\n

Collagen against wrinkles<\/h2>\n

The lightweight formula stimulates the production of collagen and elastin<\/a>, helping to reduce fine lines and wrinkles and firm the skin, in addition to brightening and even skin tone. The fat-soluble form of vitamin C, called tetrahexyldecyl ascorbate, is able to penetrate deep into the skin, where it exerts its antioxidant action with minimal irritation.<\/p>\n

How to get rid of pigmentation<\/h2>\n

\"\"Vitamin C inhibits the production of the skin pigment melanin<\/a>, responsible for age spots and excessive pigmentation, through its action on the activity of the enzyme tyrosinase. As a result, the C-TETRA serum lightens hyperpigmentation<\/a> and brightens the skin overall.<\/p>\n

100% stable serum with vitamin C<\/h2>\n

C-TETRA serum does not contain any water, making it 100% stable. You can be sure that the vitamin C does not degrade during the consumption of the product. The serum therefore remains highly effective – from the first to the last drop!<\/p>\n

Rejuvenation with CSA<\/h2>\n

C-TETRA is enriched with nourishing nourishing oils whose effect is enhanced by the rejuvenating effect of vitamin C. The serum is quickly absorbed and is ideal for anti-aging care as part of CSA’s anti-wrinkle philosophy of using vitamin C, sun protection and vitamin A<\/a>.
