Umikiss Neck Firming Cream NAD+ & GHK-Cu Peptide — 1.7oz Tighten & Lift with Hyaluronic Acid and Niacinamide

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

This rich 1.7 oz cream blends a dual-action approach—cellular support from NAD+ plus collagen-stimulating GHK-Cu peptide—along with hyaluronic acid, niacinamide and retinol to address sagging, fine lines and uneven texture. It’s formulated for daily use on the neck, lower face and chest to improve skin resilience and moisture over time. Fast-absorbing and luxuriously textured, the formula layers easily under sunscreen or makeup for morning routines and also works overnight as part of an evening regimen.

How does this cream help reduce the appearance of a turkey neck?

The formula combines ingredients aimed at firming and plumping skin architecture. NAD+ supports cellular energy processes while GHK-Cu encourages collagen and matrix support to improve skin’s tautness; hyaluronic acid replenishes moisture for immediate smoothness.

• NAD+ to support cellular renewal and skin vitality
• GHK-Cu peptide to promote collagen-related firmness
• Hyaluronic acid for visible hydration and softer lines

Will it work on both neck and décolleté, and how should I apply it?

Yes—the texture and concentration are formulated for thin, delicate skin across the neck, jawline and chest. Apply a small amount twice daily: smooth upward strokes across the neck and gentle pats over the décolleté to promote absorption without tugging.

• Use morning and evening on clean skin for best results
• Stroke upward from collarbone to jawline to encourage lifting motion
• Allow to absorb fully before sunscreen or makeup

What active ingredients are included and what do they do?

The cream combines a multi-active blend to target hydration, tone and texture. Niacinamide helps even skin tone and strengthen the barrier, retinol supports surface renewal, and botanical extracts like centella and camellia provide soothing antioxidant benefits.

• Niacinamide: brightening and barrier support
• Retinol: exfoliation and smoother texture
• Caffeine & Camellia Sinensis: antioxidants to refresh and energize skin look

How quickly will I notice results and are there any precautions?

Immediate improvements in hydration and surface smoothing can appear after the first use thanks to hyaluronic acid and emollients. Firmer contours and reduced appearance of fine lines typically develop with consistent use over several weeks as collagen-supporting ingredients take effect. Patch-test if you have sensitive skin, and introduce retinol slowly to minimize irritation.

• Hydration visible instantly after application
• Noticeable contour and texture changes often after weeks of regular use
• Patch-test recommended; use sunscreen during daytime when using retinol

Who this is for: Ideal for adults concerned with early to moderate neck and décolleté laxity, fine lines, or uneven skin tone who want a targeted, multi-ingredient cream to incorporate into daily care. Suited for those who prefer a peptide-forward approach combined with hydration and gentle resurfacing actives; not recommended for those who cannot tolerate retinol or active peptides without prior patch testing.
