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 Essence is a dream and has kept the clarity of my skin bright. I experienced no reactions or sensitivity. It is lightly emollient which is great for my oily leaning skin. It is quite a bit more viscous than what one would think of as in essence, more of a lightly hydrating lotion. Since it already contains a variety of peptides, I love stacking it with my copper peptide serum and using it as my moisture step in my routine. I also love the addition of NAD which I take in the injectable form so appreciate it topically as well. I will be keeping this item in my regimen for the foreseeable future.

Numbuzin No. 9 Essence Toner completely blew me away. The texture is thicker than a typical toner—more like a watery essence—and it leaves my skin instantly hydrated, dewy, and bouncy. I apply it with my hands right after cleansing, and it soaks in beautifully without any stickiness.After using it for about 2 weeks, I noticed a visible glow and smoother texture. It gives that “glass skin” effect without having to layer tons of products. My dry patches are gone, and my makeup sits better too.Pros:• Deep hydration without heaviness• Boosts glow and evens out skin tone• Great for layering or as a one-step prep• No irritation or fragrance overloadCons:• Slightly pricier than drugstore toners, but worth it• You go through it quickly because it’s so nice to layer

My HRT doctor turned me onto NAD+ 3 years ago, and it’s done amazing things to help recover my metabolism since menopause. So why not slap some on your face? I’ve been using this for a few months now and the biggest results are under the eyes. Tight,no purple circles, and no wrinkles. It gives off this nice, shiny and youthful glow. I’ve gotten so many compliments since starting on my NAD+ journey. Zero irritation on my sensitive skin. No noticeable scent. I use it consistently twice daily combined with other products, and my skin is moisturized and glows.

I love their products in general. I just started using it. The texture is a combination of snail mucin and moisturizer. It does absorb easily. My face does feel hydrated afterwards with a glow. It also layers well. Highly recommended as an addition to your skincare routine

I was curious what the hype was all about – and whoa, talk about results! I used this product consistently for about a month or so, and noticed some of the lines on my face were softening. I also started to notice my cheeks were a bit slimmer. I’m not sure if it’s solely because this product, as I also use a gua sha tool to massage my face and eat a healthy diet. But I have definitely noticed a difference and made sure that I used it day and night to see any actual results. My neck lines have also softened and lightened a bit. The combination of no. 9 and 5+ vitamin serum has made visible improvements! I wish I took a before and after pic, but honestly didn’t think I would see a difference, I was mistaken.As far as routine, I start with a toner, 5+ vitamin serum, 9 serum, moisturizer and sunscreen. Simple, yet effective. For reference, I have mature skin. At night, I also apply a small amount on the back of my hands, you’ll see results the next morning. Don’t forget your neck and chest too. I hope Numbuzin never changes their formulations!

This "viral" K beauty serum has a great feel with the sticky cream quickly absorbing into the skin. After several days use, I've already notice a small improvement in face glow and smoother feel. My sensitive skin often reacts to new products, but both this serum and corresponding face mask are gentle and scent free. I highly recommend this product.

This stuff is AMAZING. When I upped my tretinoin dosage to 0.1%, I was dealing with so much flaking skin (and my skin is already dry) and no matter how much hydration serums and moisturizers I used, nothing would help. I added this to my routine and the flakiness was gone literally within a day, even after upping to the strongest prescription retinoid, tazarotene 0.1%. The absorbency is great, no scent, gives a great healthy glow, and the value for money is well worth it. I will always be purchasing this product bc it’s worked miracles on my skins hydration.
