numbuzin No.9 NAD+ Peptide Lifting Serum for Face and Body, Firming & Wrinkles, 50 Peptide Essence for Sagging Skin, Fine Lines & Elasticity, Hydrating & Tightening Formula, Korean Skincare 1.69 fl oz

I’ve been using the Numbuzin No.9 NAD+ Bio Lifting-sil Essence for a few weeks now, and I’m honestly impressed with the results. The texture is lightweight and silky, and it absorbs quickly without leaving any sticky residue. My skin feels instantly hydrated and smoother after each use. What I love most is how firm and plump my skin looks. The formula with NAD+ and peptides really seems to improve elasticity and give a healthy glow. Fine lines appear softer, and my overall complexion looks brighter and more refreshed. It layers beautifully under moisturizer and makeup, and it hasn’t caused any irritation or breakouts on my skin. A little goes a long way, so the bottle lasts. If you’re looking for an essence that helps with firmness, hydration, and anti-aging benefits, I definitely recommend giving this one a try!

This essence was a life saver after my skin became severely irritated after dermaplaning. It absorbs well and left my skin feeling super hydrated and plump. By the next morning my skin was no longer red and felt much better. I highly recommend this

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!!

Haven't had this product long enough to be able to say if it does what it says however, it's a really nice formulation. Feels great on the skin and if you are into Korean Skincare and skin flooding it's easy to work into the regimen. I have been a licensed esthetician for 31 years and I can tell you this is an elegant, luxury type of product at an incredibly reasonable price. In addition, Numbuzin makes some really great skincare!

I've been using this for a few weeks now and I think it's pretty nice. I like the thicker consistency of this serum, it's like a cross between a serum and a moisturizer. With consistent use, I feel that it's improved the softness of my skin somewhat. I enjoy the subtle glow and the boost of hydration. It fits decently into my skincare routine, but there's nothing really special about it. I'm not sure if I'll repurchase it once I run out. I've used several numbuzin products that I have enjoyed but they've never become permanent staples in my routine (except for their setting powder - that thing is absolute perfection). I really dislike the bottle and the dispenser. The nozzle is way too short so it's difficult to prevent the product from smearing on the bottle. The bottle itself needs to be held at an annoying angle to dispense, otherwise nothing comes out, so the combination of these issues is frustrating. If they improve the container, I would probably consider repurchasing this serum.

I’ve been using Numbuzin No.9 NAD + Peptide serum in my PM routine for over a month now, and honestly, I’m seeing a difference—my skin feels so much more hydrated and those fine lines are definitely looking softer. The texture is a little gooey at first, but it melts right in just like a hyaluronic acid serum. I'm really liking the results, so it's definitely staying in the rotation for a while!

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-term skin support and firmness, rather than just surface-level hydration. The finish is soft and slightly luminous — not greasy, not sticky — just healthy-looking skin. It layers well both morning and night and works nicely under moisturizer and sunscreen. The scent is very light and clean, barely noticeable, which I prefer. It fades quickly and doesn’t interfere with other products. Another major plus for me is availability. I had previously been ordering this directly from Korea, so I was genuinely happy to see it available on Amazon. That alone makes it much more convenient to repurchase — which I clearly plan to continue doing. In terms of value, this serum performs exceptionally well for the price, especially compared to other NAD+ and peptide-based formulations. A little goes a long way, and the results make it worth keeping in rotation. Overall, this has become a staple in my routine. If you’re interested in NAD+ skincare, peptides, and long-term skin quality improvements, this is absolutely worth trying.

Very viscous.., like light mozzarella cheese off of a pizza. In my mind, the more viscous, the higher concentration of the active ingredient. I am happy. Feels great on my skin. I think it does the job, but it is part of a carefully crafted multilayer skincare routine and its singular benefits are hard to assess. Will I buy more when I run out? Absolutely yes! Every time I run out, I will refill.

What an amazing serum, I can tell a difference in my skin after a couple of weeks, along with the toner and eye cream this combo has given me bouncy glowing skin that I thought was impossible at my age. It does not sting my sensitive skin and I find myself reaching for this more than my other peptide serums as it feels very hydrating. Give it a try, you will not be disappointed.

😍😍😍😍😍😍😍😍😍😍

Muy buena compra, ya era un producto que estoy utilizando y me gusta mucho. EL vendedor mandó el producto muy rápido y llegó todo bien. El producto es una maravilla, mucha hidratación, activos que se sienten y casi ni hace falta usar una crema encima de este serum.

رائع وهمي للشد والنضاره

Ho acquistato questo siero dopo aver visto tante opinioni positive e non sono rimasta delusa! La texture è leggera ma molto idratante, si assorbe bene e lascia la pelle morbida, più luminosa e compatta fin dalle prime applicazioni. L’ho inserito nella mia routine mattina e sera prima della crema e ho notato miglioramento di elasticità e idratazione. Ottimo anche come base trucco grazie alla sua consistenza non appiccicosa. Rapporto qualità-prezzo davvero buono per un prodotto anti-età così efficace.
