This formula combines two of the most powerful brightening agents in skincare: pure Vitamin C and Pycnogenol® both solubilized in a completely water-free formula for ideal stability. Vitamin C and Pycnogenol® both are effective antioxidants that brighten the skin tone and reduce signs of aging. A serum that works to nurture the skin with the aim of enhancing hydration and improving the appearance of skin’s elasticity.

Pycnogenol® is a natural plant extract derived from the pine bark of French maritime pine trees. It contains procyanidins, bioflavonoids, and organic acids that work in synergy to rejuvenate the skin, with the aim of enhancing skin hydration and elasticity. With the ability to selectively bind to collagen and elastin, Pycnogenol® protects these proteins from degradation, helping to nourish the skin from the inside out. Being a unique and powerful antioxidant, Pycnogenol® scavenges for free radicals before they cause damage by oxidative stress. It can also recycle oxidized Vitamin C to restore its activity. The REEHDUS BIOTECH 5% Ascorbic acid + 5% Pycnogenol® is free of artificial colors.

Vitamin C (ascorbic acid) is a proven skin-brightener and antioxidant for decades. It boosts collagen formation and effectively targets visible signs of aging, giving skin the much-needed glow. The effectiveness of Vitamin C majorly depends upon the concentration of pure Vitamin C delivered to your deeper layer of skin. If a serum delivers 5-10 % of pure Vitamin C right into the dermis, it works like a magic wand. However, Vitamin C is highly unstable in its purest form (L-Ascorbic Acid) and loses its efficacy when exposed to air or light.

Notes: pure L-Ascorbic acid is highly unstable in formulations that contain water and use of it in formulations containing water is highly discouraged. Our REEHDUS BIOTECH 5%Ascorbic acid + 5%Pycnogenol® formulation is a water-free, stable solution, and may feel slightly “oily” for a few seconds after application, despite the fact that it is completely free of oil.


Brightens Skin – Pure L- Ascorbic Acid has an immense brightening effect. It’s formulated to make skin glow by removing blemishes and fine lines. Vitamin C is highly effective in stopping melanin-biosynthesis, which leads to skin brightening. L- Ascorbic Acid is the most potent form compared to its derivatives and it’s safe to use and penetrates the skin from within to lighten the skin tone, giving it a radiant look.

Fights Hyperpigmentation – Hyperpigmentation is caused due to unprotected sun exposure. 5% Ascorbic Acid + Pycnogenol® neutralizes free radicals and prevents inflammatory processes to slow down photoaging that causes pigmentation. It has a direct effect on hyperpigmentation – including age spots, sun spots, and melasma. The antioxidant properties of Vitamin C combined with Pycnogenol® protect against UV induced photodamage and boosts Hyaluronic acid production which keeps the skin cool and hydrated.”
