Aqua B3
A lightweight hydrating serum formulated to support skin comfort, moisture retention, and a more even-looking complexion. Humectants and a mineral-rich sea kelp bioferment help maintain hydration, while niacinamide contributes to improved surface texture, balanced-looking skin, and reduced dullness over time. Suitable for all skin types, including sensitive and younger skin.

Olio di C
An antioxidant-focused oil serum designed to support skin softness, elasticity, and overall comfort. Formulated with an oil-soluble vitamin C derivative and vitamin E, it helps enhance the look of brightness and skin vitality while emollient lipids leave the skin feeling smooth, supple, and well conditioned.

Niacinamide - Vitamin B3 (10%): Strengthens the skin barrier, regulates sebum, and reduces inflammation. Helps minimize pores, fine lines, and hyperpigmentation while improving elasticity and tone. Suitable for both aging and acne-prone skin.

Sea Kelp Bioferment: Fermented extract rich in nutrients and antioxidants that hydrate, soothe, and protect. Supports collagen production, repairs the barrier, and enhances skin smoothness and resilience.

Vitamin C - Tetrahexyldecyl Ascorbate (10%): Stable, oil-soluble Vitamin C that penetrates effectively to boost collagen, smooth fine lines, and improve texture while brightening the complexion and protecting against oxidative stress.

Moroccan Tansy - Tanacetum annuum: Soothes irritation and redness, calms sensitive skin, and provides antioxidant defense to support an even, healthy tone.

Caprylic/Capric Triglyceride + Olive Squalane: Lightweight emollients that mimic skin’s natural oils, deeply hydrate, enhance elasticity, and reinforce the barrier for lasting softness.
