Umikiss NAD+ & GHK-Cu Neck Firming Cream 1.7oz — Lift & Hydrate with Retinol + Hyaluronic Acid

Umikiss NAD+ & GHK-Cu Peptide Neck Firming Cream is a concentrated anti-aging moisturizer designed to visibly lift and firm the neck, jawline, and décolleté while delivering deep hydration and brightness.

This lightweight yet rich cream combines cellular-supporting NAD+ with the collagen-promoting GHK-Cu peptide and a lineup of proven actives to address sagging skin, fine lines, and uneven tone. Formulated for daily use, the 1.7 oz jar is suitable for targeted neck treatments and broader face or décolleté routines. The formula also includes hyaluronic acid for moisture retention, niacinamide for tone correction, and retinol for surface texture refinement, giving a multi-pronged approach to skin renewal without heavy or greasy residue.

How does this cream help firm a sagging neck?

The product pairs NAD+, which supports cellular energy processes, with GHK-Cu, a peptide that encourages the skin’s structural proteins. Together they aim to improve skin resiliency and support a tighter-looking contour over time. Regular application helps the skin appear more lifted and less lax around the jawline and neck.

• Dual active core: NAD+ for cellular support and GHK-Cu for collagen-building.
• Targets sagging at the jawline, under the chin, and across the neck.
• Light but concentrated texture absorbs to avoid heaviness under clothing.

Will this reduce fine lines and improve skin texture?

Yes — the cream combines retinol and niacinamide to address surface lines and refine skin texture while minimizing the appearance of pores and uneven tone. Hyaluronic acid binds moisture to smooth fine creases, giving skin a plumper, softer look after continued use.

• Retinol for gentle cell turnover and smoothing effects.
• Niacinamide brightens and strengthens the skin barrier.
• Hyaluronic acid provides immediate and lasting hydration for softer skin.

How should I use it in my daily routine?

Apply a pea-to-dime-sized amount onto clean, dry skin once or twice daily, concentrating on the neck, jawline and décolleté. Smooth upward strokes from collarbone to chin help encourage a lifting sensation. If using retinol at night, pair with sunscreen during daytime to protect the renewed skin surface.

• Use morning and/or evening after cleansing and before heavier creams or sunscreen.
• Massage upward toward the jaw to support lifting benefits.
• Introduce gradually if you’re new to retinol to minimize sensitivity.

Is this safe for sensitive skin and around the eye area?

The formula balances active ingredients with calming extracts like centella asiatica to soothe and support skin. It is designed to be gentle enough for the delicate neck and eye-contour when used sparingly, though patch testing is recommended for very reactive skin types. Avoid direct contact with the eye and discontinue if irritation occurs.

• Centella asiatica and green tea extract help calm and protect.
• Use sparingly near the orbital bone; avoid eyelids and inner eye.
• Patch test before first use for sensitive skin.

Who is this for? This cream is aimed at individuals noticing loss of firmness, crepey texture, or early-to-moderate signs of aging on the neck, jawline and décolleté. It suits those seeking a science-forward topical treatment that combines peptides, NAD+, and skin-renewing ingredients with daily hydration. Ideal for people wanting a targeted lifting and brightening product that can integrate into existing skincare routines; consult a dermatologist for advanced or medical concerns.
