been using this retinol for a month now and i can see the difference of the skin texture. its nicer now

i was hesitant to use retinol since i heard it may cause purging. I tried to use this every other day first but i think it seems great on my skin

It feels nice. It didn't dry or irritated my sensitive skin. Great..

This product has a very rich retinol oil! It makes my face feel really smooth, but becareful to not use too much. It is pretty strong, so I don't put to much to avoid my face from purging. Make sure to use sunscreen the next day.

I’ve been searching for a non drying non irritating retinol for a long time and I’m so glad I found it!!

Love the product, it is gentle on my skin and it works!

Для пегментации и против морщин

I've been using this for a few weeks now, and so far I have not broken out. It's light, and sinks into the skin quickly. I tend to use it at night and always make sure to use sunscreen when I go out. I've noticed some of my dark spots lightening so far.

I started out with the cosrx cream and started using this after. I did not irritate my skin, although I have yet to see definite results on my skin.

The Cosrx Retinol oil is a dry to the to the touch oil, to aid with fine line and wrinkles.

Great price, great product. Makes my skin feel amazing. help keep my skin moisturized and work on fine lines wrinkles plus skin clarity.

Such great value getting through the Ready, Set, Glow program. I was initially apprehensive to try a Retinol product but this only contained 0.5% retinol which was great for beginners. I would say that I started slowly by using it only once a week and slowly moving to twice a week. I can't say that I see too much of a difference after using it for 3 weeks but understand that this is a long term product.

i received this two weeks ago, have managed to use it 2 or 3 times a week and i am super glad. its so light and i havent had any reactions to it. my skin appears brighter and my breakouts have reduced in frequency, cosrx really never disappoints

This is the best oil i used .it is not drying ,its a great anti aging products i have ever used ,it has reduced my fine lines ,and gave that firmness to my skin .and it also has squalane which is skin friendly ingredient which helped me in moisturising my skin .whereas retinol is sometimes drying because of squalane it doesn’t .i must say cosrx never disappoints.i started using twice a week and gradually every alternative days.

(R.S.G) This is my first retinol.I am still in the process of trying it.it doesn’t leave my skin dry after use. I have always loved cosrx products so i am sure I would love this too.

I am 21 and someone told me to start using ratinol when you turn 2☆, this oil was a great start

first time trying an retinoid and ui'm very impressed with the results. I tend to always like CosRX products and this is no exception

Does a great job and doesn't irritate the skin

New to this whole retinol thing. I did a bunch of research, I use this about 3 times a week, at night, cleanse, eye cream, retinol then Hyaluronic acid. My skin the morning is so soft. I love it

Nice packaging, I cannot wait to try it.

I’ve always heard the great things about the COSRX brand, and I have been using this retinol oil, which has helped me understand why! It’s very effective – I use about 4-5 drops, a total 2-3 nights per week. Although I’m only 26, I have noticed a few fine lines that are beginning to develop, particularly on my forehead (I’ve been told I have a very expressive face, lol). This is a retinol oil rather than a regular serum. I am using it at night and layering it with my retinoid moisturizer.

Liquid form I love it so much ill continue to buy

I love Corsx brand and tried several different products and the main thing with it - you should carefully follow the instructions. Dont overdo, especially with retinol, its better to start lightly and do a test on a small patch of skin first. I like this Retinol oil, but when applied incorrectly ( read - on the skin that wasn't prepared/ moisturized well first) it can cause dryiness or&acne outbreaks. But thats fair for ANY retinol products in general. Overall, Im satisfied with the first results - my skintone looks more even after just a 2 weeks.

It’s a good product to add to my skincare routine.

It’s was a good product ever guys you must grab and try it once at last It’s was a good product ever guys you must grab and try it once at last It’s was a good product ever guys you must grab and try it once

I’ve been using retinols/retinals for many years. Serums, creams, eye creams - I’ve tried them all. I didn’t think a new retinol serum could surprise me, but the Cosrx 0.5 Retinol Oil exceeded my expectations because of its lovely smooth texture. This serum just glides on my dry skin and absorbs like a dream. Since I already have a high retinol tolerance I didn’t expect there to be any irritation and there wasn’t. I hope they come out with a higher percentage version. Would definitely purchase that! My only complaint is that the price is bit higher than other similar products.

It is my second retinol product. I think this retinol oil is perfect for those who want to start using retinol. It will take a while to finish the bottle so it's nice. I can see that this product helps prevent pimples and my skin looks healthy. 10/10

Best for anti aging, wrinkle and fine line. Can combine with black tea or green tea serum and cream is good. However, use only 2-3 times a week is ok.

It's really work with my skin , and this is my second time

I see my pores become smoother in appearance the next day after using it. It's shocking. So I think this is effective. It is an oil, so it does feel a little oily but absorbs pretty quickly into the skin. I like to use it because I see effects but this smells a little like vegetable oil when you spread it across the face. But of course if we leave the scent aside, this is a great great product.
