Most Helpful Positive Review combination skin and prone to hormonal acne: helps heal acne
I am 31 years old and have combination skin, very prone to hormonal acne. When I started using this serum, I went at it all wrong and my skin reacted quite badly... But now I love it and can't live without it! This was the first vitamin-C serum I've used. I started only using it at night, a few drops after the toner. But I used it every night for 5 or 6 days. During these first few days, every time i applied the serum (even if just a drop or 2) my skin would became pinkish and very warm. The heat sensation would last for a couple of minutes and then subside. But I should have understood then, that my skin was not used to this, and should have gone slower with the product. By the end of this first week I had a few white heads popping up in the cheeks and forehead (where I don't usually have acne). I stopped using it for a week and let my skin get back to normal. After this I tried again, but this time I did it has recommended on wishtrendTV: first day mixed a drop with my night cream -> slightly pink on my cheeks, slightly warm; two days without using it; fourth day one drop with my cream; one day without using; sixth day one drop after toner, let absorb, follow with night cream -> slightly pinkish face, slightly warm skin. The second week I decided to go with what my skin was saying: only using it every other day or every two days, never more than a drop, always at night, always using sunscreen in the mornings. And it worked! Now I've been using for 6 months, every night! My acne scars disappear a lot faster, the fine lines in my forehead are less noticeable and overall my skin is brighter. It was hard to get the hang of it in the begin, specially if we don't listen to our skin needs, but i guarantee it does help improve the skin condition with time! Give it a try!
Most Helpful Critical Review Great product, poor storage
I've used the product before and it's good but takes time to see results. It brightens your complexion and gives it a healthy glow. However you must use sunscreen after. The item that was sent to me was a bit disappointing though. I did noticed the serum already turned yellow meaning it has already oxidized. I'm aware that after opening a vitamin c package, it will oxidize over time. However this was a new unopened package. This meant that the product wasn't stored properly which caused oxidation. Will be returning it.

I'm new to skincare and don't know much about labels and stuff. It passed my mind and I didn't read the ingredients for this. One thing I avoid in skincare are essential oils. Essential oils break me out. This has essential oils. I do not recommend if you have sensitive skin or if your face breaks out from essential oils! Burns!
Best Vit-C serum out there
Mysha from Redmond, WA
I finished using first bottle of this amazing find, and OMG! This product from Klairs is absolutely amazing. My facial skin is visibly less spotted after using this serum. I use it with Klairs Vit-e mask and these two are a definite formula for spotless skin. Off to order my second bottle.
took time to get used to, but a good product
Sami from California
I alternate this in the mornings with the Ordinary niacinamide serum. The first few times, my skin got warm and slightly irritated, so I switched to using this every other morning, and made sure to use sunscreen.
Used for 8 months
Cailynn from spartanburg sc
I used this for 8 months with no difference with my acne scars. I do not recommend this. It does leave your skin looking glowy which is nice but any oil will do the same. The smell is like a chemical smell. I am now going to try niacinamide!
Careful if you're acne prone!
lizzy from chicago,il
I was excited to try my first vitamin C, especially since this such good reviews. But I am very acne prone and immediately this product made me break out. It is also very oily, so it is best to mix with a lotion/night cream. It just wasn't for me.

I use this in the morning after cleansing and before I use moisturizer. It's very light and lightly scented. I have noticed a difference in my skin since using this! My skin is feels smoother and looks brighter , dark spots are fading and it DOES NOT irritate my skin! Most products, especially vitamin c serums, irritate my skin so much.
Catie from Oshkosh, WI
This by far is the best product I have ever used on my face. Whenever I use it, my skin glows and looks fresh ! I would highly recommend this product to anyone wanting to add some moisture to their skin and improve their complexion.
Gentle, Glowing and Light
Monalisa from undisclosed
It cares and corrects the skin while being mild and gentle. I have a dark, sensitive, acne prone skin. This product has changed the texture and quality of my skin after 5 weeks of using it. It is definitely helping in making my skin smooth and even. After using this product, I have noticed that my skin has brightened up as well. It is an awesome product when used in conjunction with the Vitamine E. A small amount is all you need- probably 2-3 drops for your entire face and neck. It is definitely good value for money and lasts long as well. HUGE FAN.

My favourite serum
Meherun from undisclosed
I am a big fan of this serum . The effect of the product on my skin is amazing . Even I suggested it to my mom who is in her 40s . And she loved it . It is very gentle . It looks like oily but when it gets fully absorbed into the skin it doesn't look oily . A great night serum
Perfect intro to Vitamin C
LAO from undisclosed
This is my first time using a vitamin c product and it definitely showed improvements to my complexion and overall brightness. I notice when I skip a day how dull my skin looks. Definitely worth it - a plus that this product doesn't need to be refrigerated. Purchased in April 2020.
molly from undisclosed
I absolutely love this vitamin serum. A few drops in the morning and evening and my skin is glowing. Wonderful product.
Jiyoon from undisclosed
The vitamin C drops have drastically helped my my hyperpigmentation and dark spots. It has also just brightened up my dull complexion, I actually look more healthy and well.
Meghan from undisclosed
My first time using a vitamin drop and this one is great! My skin looks a lot brighter than before, and I can feel that my skin tone has evened out. This, with a moisturizer makes my skin look and feel more dewy in the mornings!
Weird scent, worth the buy
Candice from New York, NY
Smells a little like industrial equipment or coins but literally looked like a glowy angel within a week. Didn't expect such quick results but was pleasantly surprised by my skin in a mirror reflection. Goes on warm and a little oily but so worth it, especially for the price.
Henschel from undisclosed
Usually Vitamin C oil is too strong for my skin but this one was just right. I really liked it. It's not something I use everyday. Just ever now and then when I use the midnight blue cream or klairs freshly juiced vitamin c mask. I like the bottle and applicator.
Mona from undisclosed
I used the vitamin drops for two weeks and from the third day I noticed the dead skin on my face were gently peeling away! Now my skin is more brighter than before. Thanks to klairs vitamin drops.
Jane Doe from MN
I just got this today. The serum feels silky when applied to the face. Before, I was using Drunk Elephant vitamin C serum and I didn't like the texture. I hope this will be the replacement serum.
Corina from undisclosed
I love this stuff! I've been using for about a month now and the texture of my skin has improved!
Instantly felt great on my skin!
Maria from undisclosed
I was a little concerned with vitamin drops because my skin is super sensitive, but I had no allergic reaction and it felt very nice on my skin! It's also not oily whatsoever and absorbs to the skin instantly. I rly liked this product and I'm interested in the midnight blue drops as well ^^
Rona from undisclosed
I have very sensitive skin but this Vitamin C is very gentle and also my face doesn't feel itchy. It helped a little with my hyperpigmentation but I've just been using it over a month so we'll see in the long run. So far, my skin likes this product!
Christina from undisclosed
My face literally glows! Not sure if it has anything to do with my acne going away because i've been using other kpop products as well that are amazing but this absolutely hydrates my face. The product isn't too greasy or anything & a little goes a very long way. It doesn't really have a smell either. I love it! Btw I am a caramel skin toned African American so it does work on black skin!
Just bought but already in love…
Natalie from undisclosed
I just bought this and my skin already loves it. I have very sensitive skin and this is the first pure vitamin c serum I've used, and the redness has already decreased. I love that it's not too thick and not too thin or oily, it's the perfect texture for a serum!! Will update if anything changes within the next month.
