I reached that specific age where my reflection in the morning started looking a little more... tired than I actually felt. You know the look. Those faint lines on my forehead that definitely weren't there in 2019? Yeah, they decided to move in and start paying rent. So, when the numbuzin No.9 NAD+ BIO Lifting Serum started popping up on my feed promising to lift and firm without the price tag of professional treatments, I figured my face was ready for a little science experiment.
That Gummy Milky Goodness
First off, the texture is a total trip. It is not your typical watery serum that runs down your arm before you can even get it to your face. It feels more like a hybrid between a light lotion and a concentrated essence. It has this slightly "gummy" feel that I initially thought might be sticky, but it sinks in within seconds. It leaves behind this immediate, soft-focus finish that makes my skin look like it actually drank a glass of water for once. And for my sensitive-skin friends: there is no scent. No "perfume in a bottle" vibes here, just straight-up hydration.
The Zoom Call Reality Check
I put this to the ultimate test: a ten-hour day spent mostly in front of a laptop screen under those tragic office lights. Usually, by 3:00 PM, my skin looks dehydrated and my smile lines are practically shouting at me. After a week of using the numbuzin No.9 NAD+ BIO Lifting Serum, I noticed a legitimate difference in the "bounce" of my skin. It stayed plump even when the afternoon caffeine crash hit. Here is how it actually performed:
- Hydration: High. I could honestly skip moisturizer on humid days if I wanted to.
- Texture: It plays incredibly well with others. No pilling under my SPF or foundation.
- Glow: It is a subtle, healthy-looking radiance, not a greasy oil slick.
- Firming: My skin feels noticeably tighter and more "resilient" after about ten days of AM and PM use.
The Final Verdict
At around $24.40, this feels like a steal for the ingredient list. Between the NAD+ and the 50 Peptides, it is doing a lot of heavy lifting for the price of a takeout dinner. It did not magically erase every line on my face, but it made everything look smoother and more refreshed. It is the kind of product that makes you look like you have your life together, even if you are currently on your fourth cup of coffee. It has officially earned a permanent spot on my vanity.
Who Should Buy This:
- Anyone noticing the first signs of sagging or fine lines.
- Dry and dehydrated skin types looking for a serious moisture boost.
- K-beauty lovers who want high-performance ingredients without the luxury markup.
Who Should Skip This:
- People who prefer a very thin, watery serum consistency.
- Anyone who already has a peptide-heavy routine and does not want to double up.
