Radiant Complexion: THD Ascorbate clarifies and brightens, promoting a more even skin tone by reducing hyperpigmentation and dullness, leaving you with a lit-from-within glow.

Fine Line Reduction: Stimulates collagen production—doubling synthesis compared to ascorbic acid—smoothing fine lines and crow’s feet for a youthful, plump appearance.

Environmental Protection: Shields skin from UV-B damage and free radicals with powerful antioxidants, mitigating the effects of sun exposure and pollution.

Deep Hydration: Squalane and golden jojoba deliver superior moisture, enhancing skin firmness and leaving it soft, supple, and nourished without irritation.

Skin Regeneration: Organic rosehip CO2, rich in essential fatty acids, regenerates new skin cells to fade scars, even tone, and prevent wrinkles, supporting long-term skin health.

Key Ingredients

Sugarcane-derived squalane deeply hydrates and enhances skin firmness, mimicking the skin's natural oils to lock in moisture without clogging pores. Its lightweight, stable form also smooths fine lines and improves elasticity, leaving the skin soft, plump, and radiant.

Rosehip CO2, rich in Vitamins A and E and essential fatty acids, powerfully supports skin regeneration, helping to fade scars, even out skin tone, and minimize the appearance of fine lines and wrinkles for a smoother, more revitalized complexion.

Geranium essential oil supports skin clarity by balancing oil production and minimizing the appearance of pores. It also helps soothe inflammation, promote circulation, and enhance skin's natural glow.

Rose, abundant in antioxidants and natural oils, deeply hydrates and soothes the skin, reducing redness and promoting a soft, dewy complexion. Its gentle astringent properties also help tone and balance, enhancing overall radiance with a delicate, uplifting scent.

The Ritual

This powerful Vitamin C Serum contains THD Ascorbate, the most stable form of Vitamin C. Along with organic rosehip CO2, squalane, and organic golden jojoba, this antioxidant-rich formula hydrates, reduces hyperpigmentation, and promotes collagen production. 

After cleansing and misting your face, apply 2–3 drops of SÍ Vitamin C Serum to your fingertips and gently press into damp skin. Allow it to absorb fully.

For deeper overnight nourishment, follow with a few drops of Oro Rosa Face Oil to seal in hydration and wake up with radiant, renewed skin.
