Olio Di C Vitamin C Serum
10% Tetrahexyldecyl Ascorbate + Blue Tansy (Azulene) + Olive Squalane

Vitamin C serum formulated with 10% tetrahexyldecyl ascorbate, a stabilized, oil-soluble form of vitamin C, and Moroccan blue tansy. It visibly improves tone uniformity and radiance, and reduces the visible signs of aging.

Tetrahexyldecyl ascorbate has been extensively studied for its antioxidant protection against oxidative stress, its role in stimulating collagen production, and its ability to diminish dark spots. Being oil-soluble, it penetrates beyond the skin's surface more readily than water-soluble vitamin C. Paired with vitamin E, the two antioxidants reinforce each other.

Moroccan blue tansy is naturally rich in azulene, a compound clinically recognized for its anti-inflammatory properties and its ability to calm reactive skin.

100% naturally derived. Vegan skincare for sensitive skin.
Born in Italy. Made in the USA.

Skin that appears dull, with discoloration that does not fade easily. Also relevant when breakouts leave lingering marks or when overall brightness and clarity start to decline.

Suitable for all for skin types: oily, dry, normal and combination.

Sensorial

  • Scented with the fresh and delicate fragrance of simple essential oils, Ylang-Ylang and Blue Tansy.
  • Absorbs quickly on contact leaving no oily residue behind.
  • Applies smoothly and evenly.
