Its good product. It doesnt have a strong scent.

I don't know if I see any fading of my acne scars. I'll keep using it for now.

I had bumpy skin after using this, but it did help with my acne scars a bit.

I've been using it for two weeks now... Not much difference.

The texture of this is slightly thicker than a usual essence, comparable to the cosrx snail mucin essence but without the sliminess and absorbs much quicker while still moisturizing my skin. In my experience, I have noticed more of a brightening effect with this essence than the snail mucin one. I would recommend this product to those looking for a brighter more glowing complexion!

Loving it! Haven't noticed too much evening of skin tone. But skin does look brighter and more glowy! This along with the cosrx snail essence are my faves!

Didn't notice a big difference

Really does what it claims. I've seen improvement in my hyper-pigmentation and my overall complexion is brighter.

Según los ingredientes es la casi la misma cosa que la de Missha y la de SkinII que son super caras, creo que si quieres probar algo original y no gastar una fortuna, este es tu producto! Bien a nivel de hidratación y nada pegajosa.

I've been using this for about two weeks now and I can see the change in my skin. I have combination skin, and an uneven skin tone. After trying this just once I could see a slight difference the next morning, not to mention how soft it leaves your skin feeling once its absorbed. The serum itself is odd, its clear and goes on easy but it does feel sticky for about a minute or two, once it has absorbed you don't feel it at all which is great. Like other reviewers have said, use just one pump and it'll work beautifully. I would whole heartedly recommend this product as what it is, a brightening serum. It's not a moisturizer so don't expect some intense hydration. I would definitely consider this holy grail worthy tho, I've tried so many western and korean brightening products and for the price this is absolutely amazing. Only thing I do want to say, the bottle was much smaller than I expected; I was thinking it'd be like the size of the average body spray but its a bit smaller. Nonetheless, great for the price. 

I think this product is great, my skin looks more clean and firm but I have a dry skin and the hydratation isn't enough for me. 

Been using the product for a couple of months now, I don't really notice a big difference. I pair this with the COSRX Galactomyces Alcohol Free Toner. The essence is a lot more watery than other essences I tried and it doesn't seem like my skin abosrb this product well. This product also gives your face a slight shine to the forehead after application and halfway through the day, my forehead will be a lot more oily than usual. I have normal skin.

I first tried this product thanks to a sample, and I loved it. 

But once I bought the bottle, I didn't notice any real change...

It's not bad, but it's not Holy Grail material either...

Brighten up your skin after a period of time!

This works really well and is very low cost compared to other brightening/whitening serums and essences.  I love that the bottle has a pump so you get the perfect amount each time.  It took about two weeks for me to see a difference, but man, now my skin is really glowing and bright.  A word of warning: you really only need one pump for your face because as the directions say, you should use it sparingly as it can cause congested skin if too much is used.  One pump = Perfect!

This brand is literally my husband since this summer, I've been using almost every products from cosrx for now and still cant get over their low prices and high quality . I do recommend this brand to everyone who wanna dive into kbeauty , simple ingredient list , and you can see the change after 2-3 weeks of using them. I'll continue buying products from cosrx . (sometimes I prefer cosrx over my expensive products) Love you my husband!

I haven't tried many essences, but I really like this one. It has really helped me to lighten my dark marks, and keep my skin bouncy and radiant. It is also nice and soothing. I love to put it on after washing my face from sweat from exercise. 

I love this! Makes all pigment sport disappear! I will definitely rebuy!

After a few uses my faces is definitely brighter

This stuff is really effective. I use it every night after my toner and after just one week the places where I applied it became visibly brighter and some red marks from pimples faded away. I would just be careful with applying it to your nose and forehead as I think it may clog your pores.

I am amazed, after using this product only twice I really feel my skin looks a little lighter. I have sun damaged skin and it's already improving my skin!  It's slightly sticky when first applied but absorbs quickly into the skin.  There's no scent, and it's super light. Very impressed and highly recommend.
