Vitamin C Serums

Our vitamin C serums benefit the skin by protecting and brightening the skin. More, specifically, vitamin C:

• Protects from harmful free radicals that can oxidise and damage the skin.
• Promote a brighter, more radiant complexion.
• Prevent photoageing caused by environmental aggressors.
• Help manage hyperpigmentation and uneven skin tone.
• Promotes collagen production for more supple skin.

SkinCeuticals' vitamin C serums are the only topical vitamin C products formulated with the Duke Antioxidant Patent. This patent comes from SkinCeuticals founding scientist Dr. Sheldon Pinnell’s research about antioxidant formulations, having discovered formulation factors necessary for vitamin C to be effective on the skin. The effectiveness of a topical vitamin C antioxidant is dependent on the type of topical vitamin C used, the concentration and the pH of the solution. In addition to being the only brand to formulate antioxidants according to these standards, all antioxidants created by SkinCeuticals have been subjected to rigorous scientific studies to ensure optimal efficacy for sustainable skin benefits.

SkinCeuticals carries a range of vitamin C serums to suit different skin types, so everyone can enjoy the skin benefits of our potent antioxidant formulas. Discover your ideal match with our Vitamin C Serum quiz.

When choosing vitamin C serum for your skin type, we recommend:

• Dry skin types can use the CE Ferulic Vitamin C Serum, formulated with vitamin E that works in unison with vitamin C to provide antioxidant protection while also restoring moisture that dry skin often lacks.
• For sensitive skin, we also recommend the CE Ferulic Vitamin C Serum, formulated with ferulic acid and vitamin E to prevent oxidation while also replenishing and nourishing the skin.
• Oily skin and blemish prone skin should use the Silymarin CF Vitamin C Serum, a vitamin C serum formulated with a milk thistle extract that prevents oil oxidation, as well as salicylic acid to gently exfoliate the skin.
• Combination skin and normal skin types can use the Phloretin CF Vitamin C Serum, combining three potent antioxidants: vitamin C, ferulic acid, and phloretin, for optimal protection against free radicals.

Vitamin C serum can be applied both morning and night, but it’s most beneficial for morning use, to protect your skin from free radical damage throughout the day. Use your vitamin C serum after cleanser, applying 4-5 drops across a dry face, neck and chest. Follow with a hydrating serum, moisturiser and a broad-spectrum, high-SPF sunscreen.
