numbuzin No.9 NAD+ BIO Lifting Serum for Glow, Firming & Wrinkles, Peptide Facial Serum for Sagging Skin, Fine Lines & Elasticity, Hydrating & Tightening Formula, Korean Skincare 1.69 fl oz

This serum combined with the No9 Toner made such a noticeable difference in my skin within a week. It layers well with other products and does not pill. It’s definitely a staple of my skincare routine. Has great texture and absorbs so nicely into the skin. I use it in the AM & PM. This serum works great as a moisturizer also. Most of the time, in the morning I just apply sunscreen after and my skin feels hydrated all day long. I have dry/sensitive skin. It gives my skin a healthy glow without being too “glassy”. I can’t say enough good things about this serum. I’ve got this on subscription, so I don’t ever run out of it. %100 recommend.

I bought this bc I really like the no9 toner and it says they work great as a pair and they weren’t lying! This is bigger than the usually 30 ml which is great. It is a thicker milky serum that really hydrated my dry skin. It sinks into the skin within a few min and doesn’t leave a sticky feeling on the skin. It leaves a hydrated glow to my skin and helps a lot with dry fine lines which I love. It also works great under makeup no peeling. Fingers crossed that it will help with fine lines like it says but I don’t see why it won’t bc this is a great skincare line!!

This is actually a remarkable product. I started taking care of my skin about 5 years ago in my 60's. Years of cigarettes (no more) and Florida sun (a bit still) brought wrinkles and dull, dry skin. I've tried lots of products- with various successes/failures. I've whittled alll the bottles down to just 3-4 that changed my skin. I use Numbuzin 9 morning and night. At night I use The Ordinary Retinaldehyde, wait 5 minutes and then the Numbuzin 9. (In winter I'll add a moisturizer). This odd combination has CHANGED my skin. It took about 2 months to notice. My wrinkles got softer and not as deep. The tone has evened out and it's smooth. I use a tiny bit of makeup now- nothing like before. Not sure about younger women, but for "mature" lol skin, this is great stuff!

I absolutely LOVE this essense. Skin type: Sensitive, Melanated, Almost 30. Off the bat, texture-wise this is more of a lotion/moisturizer than an essense to me. Idc though. It is incredibly moisturizing and hydrating to my sensitive, parched skin in these winter months!! My skin drinks it up. Pair it with the Numbuzin 9+ Toner and you have the dynamic duo of 2025. I've been using it for about a month and alternate it as the 2nd and 3rd step in my routine depending on my daily activities. Either way, it shines in either step, blends with other products and melts into my skin. My face is left with the most beautiful glow, granting many compliments & questions on my skincare routine. I find it highly effective in plumping the skin. Overall I highly recommend and WILL BE RESTOCKING Don't walk, RUN🏃🏾‍♀️💨😍💅🏽

Not sure if it’s causing me breakouts or what. Haven’t noticed much of a difference and I’ve used the whole bottle up. Not sure if I would bother rebuying or not to be honest. Didn’t change my skin texture. It did make my skin soft though that’s about it. EDIT: it doesn’t break me out and do notice firming when I use it often. Dec 2025

I LOVE THIS STUFF! This is a dupe for a higher end product, but it is better than the more expensive brand, in my opinion. I am a 44 year old very fair caucasian female with dry skin. I apply this after cleansing, before bedtime. I use 3 pumps for my entire face: One pump for my forehead, one pump for the right side of my face, and one pump for the left side, concentrating on my undereyes. It is so smooth and silky on my skin. My skin looks immediately plumper. I wait about 15-20 minutes for my skin to drink this serum, then I seal everything in with an organic facial oil such as sweet almond oil or pumpkin seed oil, argan oil, or sometimes even castor oil. You can use whatever oil you want to, but it’s good to seal this serum in for maximum results. I wake up with glistening healthy, clear, moisturized skin. I have inserted a picture of my bare face just after waking up so you can see my glow. This product is effective and is truly a game changer for me. I will definitely be buying this again whenever I run out. Probably the best skincare item I have bought on Amazon at the fairest price point. Definitely a holy grail product for me!

This product is wonderful! I've only been using it for 2 weeks (twice a day) and can already see and feel the difference it's made in my skin! It plumps and firms and goes on smoothly with no pilling. It could be used as a moisturizer, but isn't as thick. It feels luxurious and melts into the skin nicely with no stickiness or residue. I'm going to get the toner to go along with it because the reviews are so good. I'll update once I try the toner with it. Get this product, you'll love it! 💜

Very good skin care product. Noticed improvement with fine lines and dull skin tone. Have ordered 2x already!_Lightweight and not sticky. I found it to be very effective. Recommend.
