A lightweight 15% pure vitamin C serum for brighter, more even skin, less noticeable dark spots and a fresh, radiant glow.
When skin starts looking dull, uneven or less radiant than usual, reach for Daylight Oasis.
At the heart of the formula is 15% L-ascorbic acid, the pure form of vitamin C with extensive research behind its use in topical skincare.
It is paired with ferulic acid and vitamin E, alongside centella, copper tripeptide-1, resveratrol and carefully selected antioxidant ingredients in a lightweight jelly texture.
With consistent use, Daylight Oasis helps dark spots and uneven tone look less noticeable while leaving skin looking brighter, smoother and more radiant.
Antioxidants also help support skin against everyday environmental stressors, making Daylight Oasis an easy addition to your morning routine before moisturiser and sunscreen.
There’s science behind the glow.
L-ascorbic acid is one of skincare’s most researched antioxidants. Topical vitamin C has been shown to improve the visible appearance of photoaged skin.
In a 6-month double-blind study of 20 women, a cream containing vitamin C and madecassoside — a compound derived from centella — improved the appearance of wrinkles, firmness and hydration. Daylight Oasis contains both vitamin C and centella.
Ferulic acid has been shown in laboratory research to help stabilise solutions containing vitamin C and vitamin E.
Copper tripeptide-1 has also been studied in topical skincare, with 12-week studies associating copper peptide formulations with firmer-looking skin and fewer visible wrinkles.
Your daily dose of vitamin C, for skin that looks fresh, radiant and awake.
