The Vitamin C 23 Serum

Siero con alta percentuale di vitamina C, sulla mia pelle pizzica un pochino dopo l’applicazione, ma è normale per il tipo di prodotto. Ha l’odore tipico di tutti i sieri con alta percentuale di vitamina C, che non a tutti piace, ma per i risultati che si ottengono, si può tranquillamente sopportare. Contiene anche acido ialuronico e vitamina E, che ha azione antiossidante. Prodotto ottimo, come tutti i prodotti coreani che non si battono.Dopo l’applicazione la pelle è subito luminosa e morbida. Ovviamente una volta aperto, si conserva in frigorifero, per evitare che gli attivi si degradino.

5-Star Review:The COSRX Vitamin C23 serum is an absolute powerhouse! Packed with Vitamin E and hyaluronic acid, it has transformed my skin. As someone with Indian skin living in the UK, I’ve struggled to find a serum that absorbs well, but this one works beautifully. It sinks right in, leaving my skin hydrated, radiant, and noticeably improved.Yes, there’s a slight smell when you first apply it, but it fades almost instantly. Honestly, it’s a small trade-off for the incredible results. My skin feels smoother, more even-toned, and healthier overall. I’m just loving it and can’t recommend it enough!

I've only used it once.That being said, it burns a tiny bit on a raw spot I have on my face and my face turned bright red! Otherwise it's OK. My redness faded quickly. It does smell like tuna. However the scent quickly dissipates. Very quickly. Especially if you put something over it, which you should. I dont like how it "dries" very sticky. Even after 5 mins my hand was still sticky. I applied snail mucin on top (as shown in my video) and it definitely lessened the sticky. Now it's soaked in a few hours, it feels nice.I notice a lot of reviews talk about the bottle only being half filled. It says in the little leaflet that is on purpose because of the ingredients used. When you open it there is a pressure release hiss. Like a soda bottle (as shown in my video) That is why there is lots of space in the bottle. If they filled it to the top that thing would burst from the pressure. And definitely spurt everywhere upon opening. I'm happy they didn't fill all the way up. I feel like this is going to be a good addition to my Cosrx family of product!

Perfect

Ça reste pour moi l indispensable à avoir, je ne peux plus m’en passer.Réduit les cicatrices d’acné, illumine la peau, l’acide hyaluronique fait que ça hydrate vraiment la peau.Je rachèterai sans hésitation!

Très bon serum, efficace.

Beautiful

Very good

bonne vita c

Very good product well worth the money and very fast delivery

I’ve been using this Vitamin C serum daily in the morning, and I’m honestly impressed with the results. My skin looks noticeably brighter and more even-toned after just a couple of weeks. It gives a subtle glow and helps wake up my complexion—perfect before sunscreen and makeup.The texture is lightweight and absorbs quickly without feeling sticky or greasy, which is a huge plus. It layers well with the rest of my routine and hasn’t caused any breakouts or irritation (and I have oily, acne-prone skin).The only thing I’d mention is the scent—it’s mild but slightly citrusy, which didn’t bother me but might be noticeable to some. Overall, this serum has become a staple in my morning skincare routine, and I’d definitely repurchase.

I have been using the COSRX Pure Vitamin C Serum with Vitamin E for a while now and I really love it. At first, I noticed it has a slightly weird smell. It is not unpleasant but definitely unique compared to other serums I have tried. Once you get used to the smell, it is no longer a problem.What I really like is how it feels on the skin. The texture is very lightweight and it absorbs quickly without leaving any sticky or greasy feeling. It gives my skin a fresh and real sensation as if it is doing something beneficial deep down rather than just sitting on the surface.Since using this serum regularly I have noticed that my skin looks brighter and more even toned. It feels softer and smoother. The added Vitamin E helps with hydration and nourishes my skin. I also appreciate that it does not irritate my skin even though it can be sensitive sometimes so it is gentle yet effective.Overall despite the odd smell at first the performance of this serum makes it totally worth it. It feels like a high quality product that works well and I would definitely recommend it to anyone looking to improve their skincare routine with a Vitamin C serum that actually delivers results.

Très bon produit

Produit top. Résultat visible dès le second jour d'application: peau lisse.

It's so good for my skin Glow:Very nice Texture:Smooth Quality:Very good

I love the glowy effect this serum gives and it also brings radiance and lightens pigmentation with consistent use. It doesn't irritate my skin at all (individual results vary) and is really niceee :) so if you are wondering whether you should buy it or not, YES YES YES. It's nice. You might take time to adjust to smell but after a few days you won't even feel it. Just store it in a cool, dark, dry place cz it's potent pure ascorbic acid. And also your skin can be irritated so be careful if Ur skin is ultra sensitive. Overall it's a great bang for your buck✨☕🧴

J’ai adoré le sérum à la vitamine C de COSRX au début : il laisse la peau lumineuse, plus uniforme, avec un joli éclat. Mais avec le temps, j’ai remarqué qu’il s’oxyde rapidement : sa couleur devient orange foncé, et sa texture devient plus huileuse.Il reste un très bon produit si on réussit à bien limiter l’exposition à l’air, à la chaleur et à la lumière. Mais honnêtement, je ne suis pas assez rigoureuse pour le fermer très vite, le stocker à l’abri, etc., donc j’ai fini par le remplacer par un autre sérum plus stable.Conclusion : super formule, mais demande beaucoup de soin pour rester efficace. Si vous êtes très minutieux(se), vous allez l’adorer. Sinon, il risque de perdre en qualité assez vite.

It's overpriced but it's better than any other Vitamin C serum obviously because of the Quantity of C. First time users, first use normal 10% Serum then if it suits you then slowly increase the quantity.

Pour l’instant le meilleur niveau compo et texture. C’est mon 2e flacon, pas de résultat notoire à ce jour, pas assez de recul probablement.Mais après avoir essayé d’autres marques, c’est cette texture qui est vraiment la meilleure.

Love this product - noticed a difference in my skin really quickly. The price is great too. I ordered it online because it's quicker and even cheaper than going to the store where I usually buy it.It does have a slight smell when you first open it, but it dissipates quickly. The serum sinks into the skin super fast and leaves it feeling really soft and smooth.If you have any skin irritation, it may sting a little but nothing unpleasant. So be careful after waxing your eyebrows etc.

Odeur très forte que je trouve désagréable. Cela dit , produit très hydratant qui fait bien le boulot.

First time with this brand, but using Vit C serum for years.So far one of my favorites in the range of price. Smells uncomfortable fishy but that is the Vit C normal smell, after some seconds over the skin the smell is gone, and personally prefer this than any extra essence. The oil is pretty thin and absorbs immediately. Haven't had any reactions but I have quite of time with this VitC concentration. I like how my skin looks, give me a glossy renewed look every morning. Any result with dark spots or fine lines, but I realized that is normal aging and nothing to do with it lol, anyway my skin looks healthy and younger for my age. Totally happy with this brand in my second week of use.Update: one month of use and still love it!

Wow au top mon nouveau sérum Vitamine C 👍

Très bon sérum visage j'ai la peau sensible bien toléré.

Très belle découverte avec ce sérum à la vitamine C.Ça picote un peu à l'application mais le résultat est là avec une diminution des tâches pigmentaires et un grain de peau affiné.J'aime vraiment beaucoup ce sérum que je rachèterai.

Love this product and will buy again. The only down side is the strong scent associated with the vit. E possibly. Other than that, it is a great product.

Ma peau était déjà habituée aux 15% de vitamine C, donc je me suis tournée vers ce produit avec une plus haute concentration. Malgré l'odeur présente, ce produit fait des miracles sur ma peau blanche, fine et sensible. En seulement 2/3 jours il a éliminé des tâches d'hyperpigmentation tenaces que d'autres produits n'arrivaient pas à effacer. mon teint est immédiatement plus lumineux. je ne m'en passerai plus c'est un nouvel indispensable, à petit prix. à mettre avant sa crème solaire protection 50.

Bon produit
