numbuzin No.9 NAD+ Peptide Lifting Serum is a serum designed for both facial and body use, formulated with NAD+ and a complex of 50 peptides to support skin firmness and elasticity. NAD+, a coenzyme naturally present in skin cells, is included to help maintain cellular energy functions, while the multi-peptide blend targets visible signs of aging such as sagging skin, fine lines, and loss of firmness. The serum aims to deliver a tightening and hydrating effect without heavy residue, making it suitable for daily application on areas prone to laxity, including the face, neck, décolletage, and other body areas.

The formula is built on a Korean skincare approach, focusing on balanced hydration and gradual improvement of skin texture. Peptides work by supporting the skin’s natural collagen and elastin structures, which can diminish over time due to environmental and intrinsic factors. NAD+ supplementation is intended to aid in cellular resilience, potentially enhancing the skin’s ability to maintain its youthful appearance. The serum does not rely on aggressive active ingredients, instead offering a gentle yet effective option for individuals seeking preventive care or addressing early signs of aging.

This product is appropriate for most skin types, including sensitive skin, as it avoids common irritants like artificial fragrances and harsh alcohols in its formulation. The lightweight texture absorbs quickly, allowing for seamless layering under moisturizers or sunscreen. Each bottle contains 1.69 fluid ounces (50 ml) of product. It does not claim instant or dramatic results, but is positioned as a supporting step in a consistent skincare routine aimed at maintaining skin firmness and hydration over time. The neutral, ingredient-focused approach makes it suitable for users who prefer science-backed, non-gimmicky serums.
