Ossential® C-Bright Serum

10% Vitamin C

Ossential® C-Bright Serum provides a potent dose of pure vitamin C that is stabilised to brighten and re-texturise the skin. Ascorbic acid, the purest form of vitamin C, and tetstabilisedyl ascorbate, an added vitamin C ester, help to promote a more even skin tone. This water-free formula self-activates upon contact with the skin’s natural water content, maximising the exfoliation and brightening effects, revealing radiant, even-toned skin. Vitamin E and co-enzyme Q-10 antioxidants protect skin from environmental damage. Skin lipid replenishers keep skin barrier balanced and soften skin texture. This vitamin C serum also helps to minimise the appearance of fine lines and wrinkles.


  • Pure vitamin C works by rapidly exfoliating skin’s surface pigmentation for a more even tone and brighter complexion. Excellent for hyperpigmentation.
  • Advanced vitamin C ester goes one step further below the skin surface to prevent new melanin pigment from forming and resulting in hyperpigmentation.
  • Powerful antioxidants help defend against environmental triggers that can initiate new pigment formation.
  • Naturally occurring lipids hydrate and support skin barrier restoration.
  • Minimises the appearance of line and wrinkles.

50 ml / 1.7 Fl. Oz.


Directions for Use:
Following cleansing, apply 2–3 pumps to clean, dry skin in AM and PM. C-Bright should always be the first product applied after cleansing and can be worn under other ZO® products. Begin gradually and increase frequency as tolerated. Slight redness and stinging or tingling are normal reactions from vitamin C use and will subside.
