Vitamin C Serum - Dark Spot Care for Sensitive Skin, 1.18 fl.oz. | 5% Pure Vitamin C & Niacinamide, EGF Peptides, Even Skin Tone, Brightening Care, Sensitive Skin-Friendly, Korean Skincare

I have really sensitive skin, so I’m always cautious with vitamin C products—but this one has been amazing for me. I use it every single day, and it’s not irritating at all, which is rare for vitamin C. I love that it combines pure vitamin C with centella asiatica, so you get the brightening benefits while still keeping your skin calm and balanced. It fits perfectly into my routine, especially since I love Korean skincare. It’s also super affordable for the quality, which makes it even better. One thing to note—make sure you use it within about 3 months after opening, since vitamin C can lose its effectiveness over time. Overall, such a great option if you have sensitive skin but still want that glow and brightening effect!

It brightened my skin within 2 weeks of using. The consistency is liquid and light which is ideal for absorption. I have nice and glowy skin. I’ve had a recent outbreak of adult acne and my skin darkens with or without picking my face, it’s just how it is with my sensitive/combo skin. It’s helped my self esteem because acne/hyperpigmentation is always my biggest insecurity. I’ve used this product before, which I ordered on another site some years ago, and I’m glad that the results and quality are still consistent!!! I started my skin care journey in 2021 and I got a little lazy along the way and stopped purchasing this product. I’m adding it back to my routine again.

This little bad boy was a “GAME CHANGER” when I added this to my face cleansing routine.. I use this product just two drops on each cheek and one on forehead after I use a soft cleanser I apply this serum. And it has completely lightened up all the dark pigmentation on my skin. I seen results after the first use. It has a slight heating up feeling on the face, but not enough to be worried about. I definitely recommend this product this is a 10 out of 10 product

I love all DearKlairs, the Vitamin C serum is just want my skin needs. Even though the packaging and labels are the exact same something is off about this product. I have the same product that I bought while living in Japan and the vitamin C serum is different I'm not sure how else to describe it.

I love this is truly has brightened my complexion and I think it also has helped me with clearing breakouts and preventing further breakouts. I have somewhat sensitive skin and I can use a full dropper on my face with no issue. Sometimes I mix it into my serum to help my serum absorb better and this does dry down quickly. It doesn’t make my face feel sticky at all and it doesn’t particularly have a scent which I enjoy. I love it and I will definitely purchase again when I run out!

Used it once and it gave me a terrible rash all over my face that took a few weeks to subside. I thought the lower concentration of vitamin C would work for my very sensitive and dry skin but it was still too much (I’ve come to accept that my skin just HATES vitamin C anything). I have been using it every evening on my déclotteé for its anti aging benefits and I have no reaction there. The serum is very light weight and absorbs easily. I love and use many Klairs products but this was a miss for me. If you are also sensitive to vitamin c, I would not recommend this product but it DOES seem to be working well on other areas for anti aging benefits. 3 stars because I can still use it on my body and it won’t go to waste.

One of my favorites! I never let myself run out. Only vitamin C serum that doesn’t irritate my face.

LOVE the Vitamin C oil serum from Klairs so much! When I initially received it I was afraid it was going to be too oily for my skin. It has turned out to be anything but. As someone concerned with ageing skin, I have to add oil to make up for the dryness that is an increasing symptom of ageing in all seasons, even in Southern California. I add several drops of this to my Korean 50 sunblock and apply generously before I use my cc cream foundation. My skin SOAKS it up. If I give it several minutes to absorb, my makeup is not too greasy and doesn’t even need powder - it will look dewy; I only apply powder lightly in the areas I want to hide pores. I also use the Klairs C serum generously on days I don’t leave the house, and even lightly on top of my makeup after a few hours to moisturize those dry areas around my eyes and mouth again. This stuff is a game-changer. I have just ordered it again! Love this and won’t be without it going forward.

Ich liebe dieses Serum, es ist Teil meiner täglichen Routine geworden. Und in Kombination mit der Klairs Freshly Juiced Vitamin E Mask hat es meine Aknenarben weniger werden lassen (man soll ja die Maske dazu kaufen, um die Wirkung zu verstärken). Allerdings muss ich dazu sagen, dass ich das volle Programm anwende, das heißt erst Double Cleansing, dann Exfoliating (mache ich täglich, mit unterschiedlichen Mitteln), dann Toner mit 7-Skin Method und 5 verschiedenen Tonern, dann ein Feuchtigkeits-Serum und/oder Essence, und dann eben die Vitamin-Tropfen und die Maske. Klingt verrückt und viel, aber für mich funktioniert es super 👍 Früher, als ich eher dachte ich muss die Haut trocken machen mit Clearasil und Garnierprodukten (grauenvoll), und ich höchstens mal eine billige Drogeriecreme einmal am Tag auftrug, hatte ich immer Pickel. Das liegt daran, weil wenn die Haut nicht ausreichend Feuchtigkeit bekommt, sie nun mal Öl produziert. Und ich dachte immer es käme wenn ich zuviel Feuchtigkeit auftragen würde, naja, dank Wishtrend TV und dank korean and japanese skincare weiß ich es nun besser ;-) Ich benutze unendlich viel Produkte und habe keine Pickel mehr. Diese Vitamintropfen von Klairs benutze ich auch eher verschwenderisch, und trotzdem habe ich weder fettige Haut noch Pickel, man muss eben das komplette Programm anwenden und westliche Gesichtspflege aus dem Kopf bekommen um Erfolge zu erzielen. In diesem Sinne, ich kann das Serum nur empfehlen!

This serum is for you If you are new to a vitamin c serum. Its non irritating works well so far on my sensitive and im hoping it will give the results (i recommend mixing it with your moisturizer and start slowly as vit C can cause purging)

Item received was yellowish, which meant it had oxidised. This will likely make it ineffective or even harmful to use as an antioxidant should not be oxidised. Item received in March 2025. Date of Manufacture is in July 2023 & expires in Jan 2026.

The best vitamin c I've tried to fade away my acne scar. I only used for 2 weeks and I've already seen the changes in my skin it brightens and looks good. Its not oily and fast absorbed by the skin. Best product ever. strongly recommended.

Lo vi en una página de rutina de limpieza coreana y la busque en Amazon ya que en el resto de páginas el precio es más elevado que aquí. La textura es oleosa pero enseguida la piel se hidrata con ella y desaparece el tacto como óleo. Si es verdad que no se puede usar por la mañanas o de día como indica el prospecto, la vitamina C con el sol crea manchas y solo se puede usar por la noche. Por el resto me gusta como es y se nota la diferencia en la piel desde el primer uso.
