The antioxidant system is further reinforced by a powerful complex: Superoxide Dismutase (SOD), Fullerenes, Melatonin, Astaxanthin, Coenzyme Q10 (Ubiquinone), Grape Seed Extract, Green Tea Extract, Ginkgo Biloba Extract and Vitamin E. Lightweight fluid texture, fast-absorbing. 0% Silicone, Alcohol, Fragrance, Colorant, Paraben, Mineral Oil. Suitable for all skin types. Volume: 30 g.

Who May Benefit

FYNE Potent Vitamin C Derivative Serum may be helpful for those who:

• want to include vitamin C in their routine but find pure ascorbic acid irritating
• notice hyperpigmentation, dark spots or post-acne marks
• want to protect their skin from oxidative stress and urban environmental damage
• aim to visibly slow signs of premature skin ageing
• prefer a clean formula without fragrance, silicones or parabens
• already use the FYNE SOD-Asta-Melatonin overnight mask and want to complement their routine with a daytime vitamin C serum

Why a Triple Vitamin C Formula

Each of the three vitamin C derivatives in FYNE's formula works differently. Ascorbyl Glucoside (AA2G) is the most stable derivative, converting to ascorbic acid in the skin. It offers a broad spectrum of activity: antioxidant, collagen synthesis, brightening. Ethyl Ascorbic Acid (EAC) is both water- and oil-soluble, penetrating deeper into skin layers and converting to pure vitamin C. Particularly effective at reducing hyperpigmentation. Sodium Ascorbyl Phosphate (SAP) is a water-soluble derivative known for its antioxidant and anti-acne properties. Together, the three derivatives cover all mechanisms of pure vitamin C action without its instability and irritation potential.

Antioxidant Complex

Beyond vitamin C, the serum contains a multi-level antioxidant system: Superoxide Dismutase (SOD) — an enzyme that neutralises superoxide radicals. Fullerenes — Nobel Prize-winning carbon molecules (C60) that act as potent free-radical scavengers. Astaxanthin from Haematococcus Pluvialis — one of the most powerful natural antioxidants. Melatonin — a cellular circadian rhythm regulator with antioxidant properties. Coenzyme Q10 (Ubiquinone) — a cellular energy cofactor with anti-ageing activity. Grape Seed Extract, Green Tea Extract and Ginkgo Biloba — polyphenols, flavonoids and terpenoids with antioxidant and vascular-protective properties.

Frequently Asked Questions

Why three vitamin C derivatives instead of one?

Each derivative has its own strengths and limitations. Ascorbyl Glucoside is the most stable. Ethyl Ascorbic Acid penetrates deeper into skin. Sodium Ascorbyl Phosphate excels at antioxidant and anti-acne activity. Combining all three delivers a synergistic effect covering the full spectrum of vitamin C benefits without compromise.

What are Fullerenes in the formula?

Fullerenes (C60) are carbon molecules whose discovery was awarded the Nobel Prize in Chemistry in 1996. In cosmetics, they act as powerful free-radical scavengers — some research suggests they are up to 172 times more effective than vitamin E. They help slow oxidative skin ageing processes.

Can it be combined with retinol?

Yes. Vitamin C serum pairs well with retinol: vitamin C in the morning for antioxidant protection, retinol in the evening for cellular renewal. This is one of the most effective and widely recommended skincare combinations.

Is this product a medicinal product?

No. FYNE Potent Vitamin C Derivative Fluid Serum is a cosmetic skincare product. It is not a medicinal product.
