No.9 NAD+ Early 20s Anti-Aging Set

I have tried a lot of eye creams at this point — everything from drugstore to K-beauty, luxury Korean skincare, biotech formulas, and higher-end clinical brands. Medicube, COSRX, HERA Signia, SkinMedica TNS, RéVive… I have gone through plenty. As someone with 52-year-old post-menopausal dry mature skin, the eye area is one of the first places I notice dehydration, creasing, and texture, so I am picky.I used this numbuzin eye cream back when it came in the syringe-style packaging, and I loved the formula but hated the packaging. It felt unnecessary, bulky, and not the easiest to use. This tube is a huge improvement. It is cleaner, easier to control, easier to travel with, and just much more practical.The texture is what makes this a great daytime eye cream for me. It is creamy and smoothing, but not thick or greasy. It gives the under-eye area a more hydrated, slightly softened look without sitting heavily on top of the skin. It also layers well under sunscreen and makeup, which is important because some eye creams pill, crease, or make concealer look worse. This one does not do that on me.Ingredient-wise, this is a strong formula for the category. Retinal is the ingredient that immediately stands out because it is a more advanced retinoid than basic retinol, and it can help support smoother-looking texture and fine lines over time. I like that it is in an eye cream format because the eye area needs something effective but not overly aggressive.The formula also includes NAD+,…

At 52 with post-menopausal dry, mature skin, I’m constantly looking for products that support skin quality, elasticity, and long-term aging rather than just quick, temporary fixes. The numbuzin No.9 NAD+ Peptide Lifting Serum has become one of those rare products that I continue to repurchase — I’m currently on my third bottle, which says a lot.

I’ve been especially interested in NAD+ as a topical ingredient, which has been gaining attention for its potential role in supporting skin energy, resilience, and overall skin health. While topical NAD+ isn’t going to create dramatic overnight changes, what it can do — and what this serum does very well — is improve overall skin quality, hydration, and firmness over time.

The texture is excellent. It’s lightweight but slightly cushiony, almost like a silky essence-serum hybrid. It spreads easily, absorbs quickly, and layers beautifully with other products. Despite being lightweight, it still provides noticeable hydration, which is especially important for my dry, mature skin.

What I’ve noticed most with consistent use is that my skin looks smoother, more refined, and more resilient. It’s not an instant dramatic change, but rather a gradual improvement in overall skin tone, bounce, and elasticity. These are exactly the types of results I look for at this stage — subtle but meaningful improvements over time.

The formula also includes 50 peptides, which complement the NAD+ beautifully. Together, they create a serum focused on long…
