I’m a calm sea when still; Powerful and mighty when in motion.

Light blue Bi-Phase brightening hydration must have.

By Valenti Biphase Brightening Serum Italian Skincare

When applied twice daily, this serum helps visibly improve skin clarity and tone with niacinamide (vitamin B3), supporting a more balanced-looking complexion and a refined skin texture. An oil-soluble vitamin C derivative provides antioxidant support, contributing to a brighter, more even-looking appearance over time.

Lightweight humectants, sea kelp bioferment, and hyaluronic acid help maintain hydration and skin comfort, while olive squalane and caprylic/capric triglyceride leave the skin feeling smooth and supple. Bisabolol and aromatic botanical extracts contribute to a calm, well-conditioned skin feel, suitable for daily use.

Formulated to work synergistically with all skin types, — normal, oily, dry and combination.
Suitable for women and men, ages 12 and above.
Recommended for uneven, blemished or acne prone skin, whether acne is caused by hormonal changes or not, sensitive skin, hyperpigmentation, enlarged pores.
Delivers results on people with early or advanced signs of ageing, fine lines or wrinkles.

A lightweight dual-phase lipid/aqueous serum with a delicate sky-blue hue when combined, and a sticking dark blue/whitish liquid that separates naturally before shaking resembling the Adriatic coast.

The aqueous phase delivers an instant sense of freshness and hydration, whilst the oil phase glides effortlessly over the skin, absorbing quickly without greasiness, sealing all the moisture in.

The natural scent recalls the clean, marine notes of the Adriatic Sea with subtle botanical undertones from Moroccan Blue Tansy and Ylang-Ylang essential oils. The finish is soft, supple, and non-sticky, leaving the skin comfortably balanced and refined all day long.

Apply 2-4 drops of product on face, neck and décolletage, gently massaging to allow serum to fully absorb. Use AM and PM for best results.

Ingredient transparency since 2007 - because you have the right to know what we put on your skin™

Niacinamide (Vitamin B3) | This water-soluble vitamin supports skin barrier integrity by stimulating ceramide synthesis and helping regulate sebum production. It visibly refines texture, minimizes the appearance of pores, and promotes a more uniform, balanced complexion.

Tetrahexyldecyl Ascorbate (Vitamin C 10%) | A stable, oil-soluble form of vitamin C that penetrates effectively into the epidermis to provide antioxidant protection and support collagen synthesis. It helps improve the look of uneven tone and dullness while maintaining compatibility with sensitive skin types.

Sea Kelp Bioferment | Rich in minerals, polysaccharides, and amino acids, this marine ferment derived from giant kelp helps maintain hydration and strengthen the skin’s natural barrier. It promotes softness, elasticity, and a smoother feel while supporting a balanced microbiota.

Hyaluronic Acid [High Molecular Weight 180 – 220 kDa] | Known for its exceptional ability to bind up to 1,000 times its weight in water, this form of hyaluronic acid forms a protective film on the surface of the skin, reducing transepidermal water loss and restoring suppleness and comfort.

Olive Squalane | A biomimetic lipid naturally derived from olives that replenishes the skin’s hydrolipidic film and limits moisture loss. It enhances flexibility and softness without a greasy residue, leaving skin smooth, silky, and protected against environmental stressors.
