numbuzin NAD+ Peptide Serum for Face, Neck & Body — 50 Peptides, Lightweight Hydrating Lift (1.69 fl oz)

numbuzin No.9 NAD+ Peptide Serum is a lightweight Korean-style serum that combines NAD+ with 50 peptides to hydrate, firm, and improve skin elasticity on the face, neck, and body.

This concentrated treatment blends an essence-like texture with serum performance to address visible sagging, fine lines, and dullness without feeling heavy. Formulated to layer smoothly under makeup and other skincare steps, it’s designed for daily use on delicate facial skin as well as the neck, décolletage, and problem areas on the body. The formula emphasizes hydration, lifting support, and a brighter, plumper-looking surface through targeted peptides and NAD+ support.

How does this serum help reduce the appearance of sagging and fine lines?

The serum delivers a high peptide count alongside NAD+ to support the skin’s appearance of firmness and resilience. Peptides are short chains of amino acids that signal the skin to appear smoother and more taut, while the NAD+ component helps the texture look refreshed and energized. Results are cosmetic and visible over consistent daily use rather than immediate structural change.

• 50 peptides included for targeted lifting and smoothing effects
• NAD+ blended to support a revitalized surface appearance
• Lightweight formula that layers under makeup without pilling

Where can I use it, and how often should I apply the serum?

This serum is formulated for multi-area use: face, neck, chest, and any body zones needing firmer-looking skin. Apply a small amount morning and evening after cleansing and toning, then follow with moisturizer and SPF in the daytime. For best results, incorporate it consistently into your daily routine.

• Suitable for face, neck, décolletage, and localized body areas
• Recommended twice daily—AM and PM—after cleansing
• Absorbs quickly, compatible with moisturizers and sunscreen

What texture and finish should I expect when using this product?

The serum has an essence-to-serum texture that feels hydrating but not greasy, leaving a dewy, natural-looking glow. It’s designed to plump the surface and smooth fine lines while providing a luminous finish that works well under makeup. The lightweight consistency minimizes clogging and allows layered actives in a routine.

• Essence-like, fast-absorbing texture
• Leaves a hydrated, glowing finish without heaviness
• Non-greasy and suitable under cosmetic products

Is this serum appropriate for sensitive or all skin types?

Formulated to be gentle for daily use, the serum is intended for a wide range of skin types. Because it contains active peptides and NAD+, patch testing is recommended for very reactive skin before widespread application. If irritation occurs, discontinue use and consult a skincare professional.

• Designed for normal, dry, combination, and oily skin types
• Patch test for sensitive or reactive skin first
• Compatible with most skincare routines when layered properly

Who is this for: numbuzin No.9 is aimed at anyone looking to boost skin firmness and hydration without heavy creams—especially people noticing early signs of sagging, fine lines, or dullness on the face, neck, and body. It’s a practical choice for those who prefer layering lightweight, active serums in a Korean skincare–inspired regimen and want a product that works across multiple areas of concern.
