ZO Skin Health Neck Complex Anti-Aging + Brightening Serum 50 ml is a targeted serum for the neck and decollete, formulated with the ZPRO antioxidant and biomimetic protein complex, Pichia Ferment Lysate, Arginine/Lysine Polypeptide and Diglucosyl Gallic Acid. It reduces the appearance of crepey skin and horizontal neck lines, improves visible laxity and contour definition and evens skin tone. Fragrance-free and alcohol-free. Apply morning and evening; use sunscreen during the day.
The skin of the neck and decollete is thinner, has fewer sebaceous glands and a weaker support network than facial skin, so it shows loss of firmness, crepey texture and pigment irregularity earlier. ZO Skin Health Neck Complex answers that anatomy with a multi-axis formula acting at once on the structural proteins of the dermis, on surface quality and on the mechanisms behind uneven tone. The texture is a fluid, fast-absorbing serum, fragrance-free and alcohol-free, for daily use morning and evening on Fitzpatrick phototypes I to VI.
The signature technology is ZPRO, described by the manufacturer as an antioxidant and biomimetic protein complex supporting the replenishment of collagen and hyaluronic acid in skin that has lost density. Biomimetic proteins imitate fragments the skin already recognises, acting as signals rather than inert surface fillers. The antioxidant part addresses the oxidative load from ultraviolet exposure and pollution, which accelerates collagen degradation.
Pichia Ferment Lysate Filtrate is a fermentation-derived biopeptide with a dual role here:
Arginine/Lysine Polypeptide is a plant-derived active for firming and lifting, with a declared focus on horizontal neck wrinkles - the folds perpendicular to the neck axis that facial products never address. Arginine and lysine are amino acids involved in structural protein synthesis; in polypeptide form they supply building material plus a surface tightening effect.
The brightening axis uses two actives. Diglucosyl Gallic Acid is described by the manufacturer as targeting 7 key factors that contribute to uneven skin tone - multi-factorial, rather than a single intervention on melanin synthesis. Alongside it, an intelligent peptide drone, an encapsulated brightening peptide, stays protected until application and is released more gradually.
In a 12-week study on 46 subjects aged 37 to 64, the manufacturer reports these self-assessed results:
The manufacturer positions it for the 37 to 64 age range, with tolerance across Fitzpatrick phototypes I to VI.
Apply to the neck and decollete, morning and evening, on clean skin. Spread it upwards from the base of the neck towards the jawline, then over the decollete, and let it absorb. In the morning, sunscreen over the treated area is mandatory: without photoprotection the results on tone are compromised. In the evening it can go under a moisturiser.
Neck Complex targets one anatomical area and integrates into a broader routine. For daily antioxidant and barrier support on the face we recommend ZO Skin Health Daily Power Defense, and for facial firmness Firming Serum. For a concentrated peptide step, ZO Skin Health Peptide Facial Refining Concentrate follows the same logic. Daily photoprotection is covered by ZO Skin Health Broad Spectrum Sunscreen SPF 50.

ZO Skin Health is the brand founded by dermatologist Zein Obagi, built on maintaining skin health rather than treating isolated symptoms. It is distributed mainly through medical practices and clinics and structured around protocols, not standalone products. Neck Complex fits that logic as a dedicated step for an area classic facial protocols leave uncovered.
