ZO Skin Health Neck Complex Anti-Aging + Brightening Serum

ZO Skin Health Neck Complex Anti-Aging + Brightening Serum 50 ml is a targeted serum for the neck and decollete, built around the ZPRO antioxidant and biomimetic protein complex, Pichia Ferment Lysate, Arginine/Lysine Polypeptide and Diglucosyl Gallic Acid, formulated for crepey texture, visible laxity, horizontal neck lines and uneven tone.

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.

ZPRO - antioxidant and biomimetic protein complex

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 - radiance and apparent density

Pichia Ferment Lysate Filtrate is a fermentation-derived biopeptide with a dual role here:

• Radiance and hydration - better light reflection from a better hydrated surface
• Appearance of skin thickness - what matters most on the neck, where thin, translucent, crepey skin dominates
• Barrier support - reinforced by Lactobacillus Ferment and Cordyceps Militaris Mycelium Extract

Arginine/Lysine Polypeptide - firming and lifting

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.

Diglucosyl Gallic Acid and the peptide drone

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.

Botanical and biotechnological support

• Scutellaria Baicalensis Root Extract - soothing and antioxidant profile
• Glycyrrhiza Uralensis (Licorice) Root Extract - classic active for uneven tone
• Melilotus Officinalis Extract - supports comfort and tone
• Buddleja Davidii Meristem Cell Culture - antioxidant support
• Hydrolyzed Sericin and Phospholipids - film-forming, barrier-supporting
• Tocopherol - vitamin E, lipophilic antioxidant
• Lactic Acid/Glycolic Acid Copolymer - copolymer form for texture and release, not a free exfoliating acid

Clinical results reported by ZO

In a 12-week study on 46 subjects aged 37 to 64, the manufacturer reports these self-assessed results:

• 98% felt the skin appeared softer and smoother
• 91% reported less visible fine lines and wrinkles
• 89% noted a reduced crepey appearance
• 80% observed a more lifted, toned appearance
• 80% saw a more even skin tone

Key benefits

• Reduces crepey skin, fine lines and wrinkles on neck and decollete
• Improves visible laxity and the definition of the neck contour
• Targets horizontal neck lines, which face care does not cover
• Brightens and evens skin tone through a multi-factorial mechanism
• Retexturises the surface for softer, smoother skin
• Long-lasting hydration without a heavy or occlusive finish
• Fragrance-free and alcohol-free, for daily use on a sensitive area

Who this serum is for

• Crepey, thin texture on the neck and decollete
• Horizontal neck folds and loss of contour definition
• Uneven tone from chronic sun exposure, in an area rarely protected like the face
• Maintenance after in-clinic procedures, once the skin has recovered and with the practitioner's approval

The manufacturer positions it for the 37 to 64 age range, with tolerance across Fitzpatrick phototypes I to VI.

How to use

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.

Timeline of results

• Immediately - smoother, better hydrated surface, subtle tightening sensation
• Weeks 1 to 2 - softer texture, skin that feels less rough to the touch
• Week 4 - crepey aspect less noticeable, tone more homogeneous
• Weeks 8 to 12 - firmness and contour definition improve; the interval measured by the manufacturer
• Beyond 12 weeks - consolidation, with continued use and photoprotection

Synergistic combinations in the ZO range

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.

Warnings and contraindications

• External use only. Avoid the eyes and mucous membranes; rinse thoroughly with water on contact
• Do not apply to broken, irritated or sunburnt skin
• Stop use on intense or persistent irritation and consult a specialist
• Daily broad-spectrum sunscreen is mandatory on the treated area
• Not recommended during pregnancy or breastfeeding without medical advice
• Ask your practitioner first if you are under dermatological treatment or have recently had a procedure in the area
• Check the INCI list on the packaging for allergens. Keep out of reach of children. Store cool, dry, away from direct sunlight

About ZO Skin Health

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.
