I purchased this bottle out of curiosity after seeing the active ingredient breakdown, and as someone in my 40s who is meticulous about skincare, I am completely blown away by the results.For a long time, I was layering two completely separate serums to get these results—one dedicated growth factor serum and one dedicated NAD serum. Having them combined into a single, beautifully formulated product is brilliant:EGF (Epidermal Growth Factor): Signals the skin to renew itself, promoting cellular repair, collagen production, and improved elasticity to target fine lines and loss of firmness.NAD+ (Nicotinamide Adenine Dinucleotide): Acts like cellular fuel—recharging cellular vitality so skin cells function at their peak, boosting radiance and preventing dullness.Bonus Collagen Extract & Peptides: Plumps and hydrates the skin, leaving a bouncy, smooth, and revitalized finish without any greasy residue.My fav skincare company has really hit a home run with this formulation! I am already eyeing their upcoming product releases (like the new face mask) because this brand genuinely delivers real, visible results. Highly recommend to anyone with mature skin looking for serious, science-backed skincare!And in case you did not see what I mentioned above, I am literally saving a ton of money per month because I am now able to buy this which is more affordably priced arguably than either one of the serums. I was previously using because I was using two serums to get the same exact result and now I’ve been able to slim them and stream line down to just this one. I mean, I cannot tell you how exciting this is for me in this economy you couldn’t ask for a better reason to buy skin care because you can do the girl math and see the savings! Lastly, I just want to report there is no fragrance truly… I’m super sensitive that kind of stuff but I’ve never found too many things from these folks that bothers my skin anyways all of their products are extremely gentle and extremely effective. I am a lifelong fan.

Uno dei migliori sieri mai provati: bastano poche gocce perché è abbastanza concentrato. Si asciuga subito e uniforma l'incarnato. Io lo uso la mattina e la sera prima della crema viso e mi piace l'effetto e la sensazione che lascia. Per me approvato!

Cosa mi piace,Ha una consistenza leggera che penetra subito. Non si limita a dare un effetto glow temporaneo, ma agisce sulla compattezza e sui pori nel tempo.Risultati: Pelle più turgida, idratata e un colorito molto più fresco e riposato. Un prodotto di k-beauty promosso a pieni voti!

At almost 46 years old and after losing 30+lbs, I was looking into treatment options for loss of tone and firmness of the skin on my neck and along my jawline. I concluded that while I’m not quite ready to try fillers, lasers or targeted ultrasound therapy yet, there was no harm in trying to incorporate a new product from one of my favorite Korean beauty brands - Medicube has always delivered solid results on their claims when I’ve used their skincare diligently for at least a month or two.In my research phase I noticed several dermatologists and cosmetic treatment clinics were offering NAD+ in their packages, so when Medicube released this product I was intrigued.The serum arrived in a heavy frosted glass bottle with a functional dosed dropper (Amen!) I have been applying the watery-gel naturally red tinted formula on cleansed and toned skin (3rd step) morning and evening. I have not experienced any redness or irritation (except immediately after plucking my eyebrows and that’s my bad) This serum does not provide moisture but that’s not what I was seeking from it - I use another serum for that - it absorbs quickly and layers wonderfully under my other skincare products, SPF and makeup.After several weeks of twice daily use, the results have been subtle but noticeable, especially in the areas that I was most concerned with. The skin on my neck is less crepey and my face in general looks more toned and firmed. I also notice that my skin reflects light a bit better without increased shine - just a nice healthy glow.I will definitely keep using this product because for the investment of a few moments of time and $16 at the time of my purchase, it is so worth it for the results I’m experiencing!

I've been using the medicube NAD EGF Firming Serum on my face and neck, and I absolutely love it! It's one of those products where I actually noticed a difference. My skin feels noticeably firmer, smoother, and more lifted after using it consistently.The serum absorbs quickly, isn't greasy or sticky, and layers perfectly with the rest of my skincare routine. My complexion looks healthier and more refreshed, and I love that it works just as well on my neck as it does on my face.If you're looking for a firming serum that delivers visible results and leaves your skin feeling tighter and more youthful, I highly recommend giving this one a try. It's definitely earned a permanent spot in my skincare routine! ⭐⭐⭐⭐⭐

Ich finde es wirklich super in Kombi mit dem Gerät 😍

Il siero, una volta applicato, tira un po’Ho comprato la crema della stessa linea, ed essendo piuttosto grassa, ho risolto il problema. Non so se ricomprerei il siero, dato che in genere trovo questi prodotti inefficaci, ma sono pochi giorni che uso questo marchio e sarei ben felice di ricredermi

Una vera bomba,mi trovo benissimo,la mia pelle e più compatta ,levigata ,luminosa e ringiovanita !!! adoro sto siero !❤️❤️❤️

I started using medicube products about 8 months ago and have been very pleased with the results. I bought this product for my neck about 2 weeks ago and have already noticed a big difference. Highly recommend this product for firming and tightening aging skin. Better than other expensive products from the dermatologist and esthetician I have purchased over the years. I am 65 and my skin looks better than it did in my 30's.

La utilicé 2 veces y he de decir que me encantó el efecto, sí cumple totalmente, gracias

My husband passed away about 16 months ago, from brain cancer, so as one can imagine my 58 yr old face was telling its tale. I had horrible lines between my eyebrows and frown lines. This serum helped my eyebrow lines look less noticeable. I don’t think the frown lines are much better, but other smaller wrinkles look a bit smoother. It’s no miracle treatment, but it’s a small difference that makes me feel a little better. About the best you can ask for in a topical product in my opinion.

Es un serum maravilloso lo comprare otra vez seguro

I’ve been using it for a week now and I definitely love the results. My skin feels smooth and hydrated.

Siero ottimo migliore del rosa a mio parere. Questo siero riesce sia ad illuminare che a compattare la pelle che risulta soda per tutto il giorno. Io lo abbino con Medicube cream vit C ( quella scatola marrone per capirci)

Très bien

I am not a skin care girly but I am trying to take care of my skin better and I love Medicube. I have very sensitive skin so I wasn't overly hopeful when I bought their face wash when it was on sale but it worked like a dream for me so I bought a few more of their products to try out and almost all of them have worked with my skin. This one in particular is fantastic. It absorbs well (a little sticky when it's drying down but once it's dry there's no stickiness left) it's super moisturizing and seems to be helping with my deep forehead wrinkles. 10/10!

Love the medicube brand! I have so many of their products and love them all! My skin has never looked better

I’m in a very nice surprise when I decided to try this product. Very lightweight. Absorbed quickly without heavy and sticky feeling. It rejuvenates and gives my tired skin a glow in seconds.

Efficace

Producto muy bueno , lo recomiendo

Bin sehr zufrieden

Sehr zufrieden

Comprato per curiosità e invece uno dei prodotti che uso tutti i giorni e la mia pelle ringrazia. La re de più tonica e si notano meno le rughe di espressione. Pori meno visibili già dopo una settimana

Only been using this for about three days and I can already see a difference amazing product. I will definitely be re-ordering this product.

Muy buenos resultados

Ça fait seulement quelques jours que j'utilise ce serum donc un peu trop pour des résultats. Mais texture agréable, aucune réaction de rongeurs ou autres. Après j'utilise pas mal de produits Medicube et j'en suis très satisfaite !

This stuff is magic. All there serums are sooooo good. This one and the Rose PDRN are my favorite. I haven’t seen any wrinkle reduction. However it makes your texture of your skin so smooth and plump and hydrated and it soaks in really fast. It doesn’t irritate my sensitive skin and it’s not greasy at all.
