I like this product. It is gentle on your face. It has .5 retinol, which most experts tout as the best thing for tightening skin and reducing wrinkles. So far so good. Highly recommend.

Kadence Medrano
I absolutely love this retinol serum. It is very gentle on my sensitive, rosacea skin. After just a couple of weeks I started using it every night and I have gotten so many compliments. I have used retinol products before that were too harsh and this one was perfect from the very first use. Will likely upgrade to the 1% over the next few months. Honestly the entire COSRX line is fantastic.

Cate
The COSRX Retinol 0.5 Oil is amazing! It’s been working wonders on my skin, reducing fine lines and promoting a smoother, more youthful appearance. The oil absorbs well without feeling greasy and doesn’t cause irritation like some retinol products can. I’ve noticed my skin looking brighter and more even after using it for a few weeks. Highly recommend this for anyone looking for an effective anti-aging solution!

I have had trouble with retinol products in the past, and this one doesn’t bother my skin at all.

Christy Harris
I was afraid the retinol would irritate my skin, but I was pleasantly surprised it didn’t.

Very nice retinol oil; light texture, easily spreadable, soaks right into my skin. No scent whatsoever. This company does recommend that you keep it in the refrigerator or a cosmetic chiller to maintain efficacy. This is typical for retinol products. At the very least, store it somewhere dark and cool. Don't store it in direct sunlight or close to a heating vent.

I love this stuff. I want to think it’s working as my skin feels great now. I’m 44 and getting signs of fine lines around my eye area. It didn’t burn me up too bad maybe caused some dryness but that’s to be expected. Just use some heavy moisturizer. Great piece for a great product.
I like this product. It is gentle on your face. It has .5 retinol, which most experts tout as the best thing for tightening skin and reducing wrinkles. So far so good. Highly recommend.
I am on my second bottle. The first one lasted 5 months and I used it daily. I’ve used other retinol serums in the past, and this one feels the best on my skin. I didn’t think I’d like the oil texture, but it’s very light and now I can’t go to bed without it!
I really like this Retinol. Actually I love all things COSRX. Ive been using their products for a few months and I can tell a difference in my skin and I’m starting to get compliments from my sisters and friends that my face looks smooth and bright! I didn’t have any acne or anything just wanting to age gracefully and I think this is truly helping. This is a light, liquid like serum. A little goes a long way. I use this then I follow up with the Hyaluronic acid from COSRX. I keep all my face potions in the fridge so putting on a cool serum makes it even nicer.
I’ve always struggled with large pores and now that I’m getting older, I’ve noticed they’ve gotten much worse. I Googled what would help shrink them and found Retinol does the job. And it does! Both of the pictures are in the sun but I couldn’t quite duplicate the exact same sun exposure/ pose but both are of my right cheek. The picture with my earring is after and the picture that is brighter is before. It’s not a huge difference but I’ve only used it twice (along with my other skincare) and can see a difference not only in pictures but in person. Also, the instructions say to use it only a few days a week as it may cause irritation and I did do a day break in between the two uses and did not experience any irritation at all. If I remember, I’ll update this with a photo in a month or two!
I absolutely love this retinol serum. It is very gentle on my sensitive, rosacea skin. After just a couple of weeks I started using it every night and I have gotten so many compliments. I have used retinol products before that were too harsh and this one was perfect from the very first use. Will likely upgrade to the 1% over the next few months. Honestly the entire COSRX line is fantastic.
I enjoy this product because of its benefits of retinol and the oil that it is in is very hydrating and a bottle lasts for a very long time. I believe I will be using this product for the rest of my days. It’s a staple in my nightly routine. It’s a very good product to prime your skin, making it easy for other products to glide on your face. A little goes a long way.
The COSRX Retinol 0.5 Oil is amazing! It’s been working wonders on my skin, reducing fine lines and promoting a smoother, more youthful appearance. The oil absorbs well without feeling greasy and doesn’t cause irritation like some retinol products can. I’ve noticed my skin looking brighter and more even after using it for a few weeks. Highly recommend this for anyone looking for an effective anti-aging solution!
It’s a fantastic product. Compared to other retinols on the market, this has only one questionable ingredient that has the potential to be an endocrine disruptor, but more science research is needed on the matter.
I have tried so many retinol products (as well as other anti-aging and skin smoothing products) and this is the best overall. I have age 50+ mature, dry, sensitive skin. A lot of retinol products end up burning my eyes or flaking my skin, they have a weird texture, smell bad, or just don’t work. This is like liquid gold. It’s in oil form. I put it on about an hour before I go to bed so it has a chance to absorb. I eliminated all other serums at night. Now I just use this after I cleanse my face. It’s all I need. My sagging chin has lifted and my skin is much more even and smooth. I didn’t have a lot of wrinkles for my age, but it’s smoothed the crow’s feet around my eyes. I’m on my 3rd bottle. I saw a difference after only about a few weeks. It’s amazing stuff!
I love this retinol serum however be aware it’s concentration is higher than others so a little goes a long way. I never had any skin irritation or any issues when applying it in my regular skincare routine. However it’s advised not to use retinol every day or when scrubbing your face. It’s very lightweight and your skin is able to absorb it nicely so it won’t leave your face oily. I noticed that if you don’t keep it in the fridge that the color of the serum may change to a darker color due to oxidation so best to keep it in a regular fridge.

I’m now up to putting it on every other day, followed up with Nivea cream and I have had no negative reaction.
I have had trouble with retinol products in the past, and this one doesn’t bother my skin at all.
This was my first purchase from this brand and I must say, that I will be repurchasing again. It works in tandem with my other Korean skincare products and I absolutely love this!! Will be ordering another, before I run out!! Absolutely stellar ingredients!!!
Este producto es maravilloso se lleva muy bien con mi piel, es producto es aceitoso sin embargo mi piel grasa lo a tolerado muy bien, siento q a la mañana siguiente de usarlo me deja la piel más suave

This brand is wonderful, it is stabilized in Bitamin E oil. Goes on smooth and causes no redness or irritation. I use it last in my skincare routine. My skin is so smooth and wrinkle free because of my daily skincare rountinr and this product .
