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.

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!

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.

First off, my skin is t-zone oily and i have a handful of acne scars and hyper pigmentation around my chin/mustache area. I have been routinely using this product for a solid week now. This doesn't burn my skin (i have thickish skin) and it doesn't have any strong smell but there is a slight smell. Its easy to apply and on good days it doesn't leave my skin oily after applying it. Overall Verdict: You have to give this product some time for you to see tremendous changes. Its slow in fading scars and hyper pigmentation but skin texture is ridiculously smooth. I like it but its really slow for me but i will continue to use it. 1. Acne Scar fading: This works well on scars that are already fading. If you have really harsh scars then it could take a lot longer (of course) but it may be disheartening to people who think it works quickly because it doesn't. 2. Skin Texture: Using this product for this purpose is actually amazing. This has really improved the texture of my skin. Its really smooth and not very bumpy. I love feeling how smooth my skin is (lol i know im not suppose to touch my face so much). 3. Hyper pigmentation: This is like the acne scar issue. Its really slow in progress. I have pigments around my chin area and i see slight changes but its not a huge difference i was expecting.

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.

I went through this entire bottle and will be purchasing another. It's soothing, and has a warming effect when applied to the face. It also doesn't leave a sticky feel. I love this on my mature skin and along with my other products.

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.
