Dear Klairs Vitamin C Serum, Gentle 5% Pure Vitamin C & EGF Peptides, for Uneven Skin Tone, Brightening, Dark Spot Care, Sensitive Skin, Non irritating, Korean Skincare 1.18 Fl Oz

This vitamin serum has a gentle yet effective formula. It absorbs well and leaves a subtle glow without irritation. My skin looks brighter and smoother with consistent use. It doesn’t feel sticky and layers well under moisturizer and sunscreen. I appreciate that it’s mild enough for regular use while still supporting a healthy, radiant complexion. Definitely a dependable vitamin serum.

You know, I'm a guy. As a guy, it's hard to swallow my pride and try these beauty products because hey, a man is supposed to look like he's been living in the woods for decades right? NO. Some guys want to look pretty and flawless too! Anyway, this serum is ridiculously amazing. Saw this on WishTrendTV randomly a long long time ago, but didn't really look into it again til I watched JoanKeem's youtube video and saw her review this. I did the whole basic cleanser, toner, moisturizer with the occasional mask... it works but... yeah. If you add this serum, I swear, the results are ten-fold. It's insane because if you hear about a product that gives you results after one use, majority of the time it is completely bull. BUT THIS. I LITERALLY saw results after one night. My face is definitely smoother, hyper-pigmentation is fading away a little faster (with exfoliating of course), skin is whitening (a little), but the best feeling is when other people notice it. After 1 week, people asked me if I was doing something new (I have pretty bad skin lol) and BAM this serum is the key. Ugh.... this serum is bomb yo. Anyway, I only use 3 drops of this (one on each cheek and one on my forehead) right after I use my toner. It has a slight tingling feeling/warmth to it as you put it on... as if your face is heating up, but it's a good feeling. It kind of shmears like oil, but it dries really nicely and helps your face feel insanely plump and moisturized. I put on my lotion right afterwards and I'm good to go. Unfortunately I don't have a before/after picture, but just trust me. This serum will seriously NOT disappoint. ps. Keep away from direct sun and any place that might heat up. I actually keep mine in the fridge cause that's what a lot of beauty gurus recommend for storing serums.

This is an amazing product! I have used several Vit C serums, but this one is the best! I use it with Jojoba oil, and sometimes with the Klairs Vitamin E mask in the evening. It has really improved my skincare.

After trying many different brands, I've finally found something to repurchase. It isn't perfect - the serum skews towards the slightly oily side and the bottle is translucent, so you have to store it somewhere dark. That said, my skin has been clear and bright thanks to this non-irritating and minimally-fragranced formula. One bottle has lasted me between 4-5 months at this point, and I'm on my third now. They suggest using the Vitamin E mask from Klairs as well, and while I wouldn't say it's necessary, it is also very nice, particularly in combination with this serum. I use the Vitamin C serum each morning and the Vitamin E mask on nights where I want an extra boost for my skin. 4 stars out of 5 because it's still more expensive than my usual skincare items (I know, I'm being picky), and because the bottle should be opaque. I find the slight oily finish to be moisturizing for my combination skin even in Los Angeles humidity, but I'd still have preferred a more natural finish.

I was originally gifted one of these but loved it so much that I bought one. It feels great on my skin and I feel it’s brightened my face and evened my skin tone. It’s a solid brand that specializes in glass skin and that dewy glow. Will purchase again.

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.

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!

Been using this product for 3 years and love how it helps to keep my skin moisturized, supple and has brightened my dark spots. I would recommend this to anyone especially older women dealing with aging spots. It is priced right for how ling it lasts.

良かったですー肌がピカピカになった。

Ich habe dieses Produkt bereits einmal komplett aufgebraucht und nachgekauft. Meine ersten Resultate waren bereits nach weniger als einer Woche erkennbar. Weniger Pickel, strahlendere Haut und sogar die trockenen, spannnenden Stellen wurden besser. Nach einer kompletten Flasche (über ein halbes Jahr lang jeden Abend benutzt) sind meine Pickelnarben komplett verschwunden, obwohl ich schon dachte, dass ich diese nie loswerden würde. Danach habe ich sozusagen ein Selbstexperiment gemacht und das Serum für einige Wochen weggelassen. Der Unterschied war enorm. Pickel kamen zurück, meine Haut war nicht mehr so ausbalanciert wie zuvor. Daher kann ich jetzt sagen: Nie mehr ohne. Dieses Serum macht meine Haut praller und ausgeglichener, fast wie eine normale (nicht trockene) Haut. Ich fühle mich wohl in meiner Haut, selbst ohne Make-Up, da die Haut ebenmäßig und strahlend wirkt.

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.

This is the first skincare product I’ve tried. I wanted something natural, chemical free so have sensitive skin. It moisturizes my skin well and feels nourishing for the skin as well. The dropper makes it easy to apply.
