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.

After using 0.1% retinol for several months, I felt ready to try my retinol tolerance and see if it could take a higher percentage. However, unlike other retinol products I have tried, Cosrx uses PURE retinol and not just retinol derivatives which means it is stronger than most other retinol products you can find in the market. I had taken this into consideration prior but still decided to test this out, fully knowing the risk. Unfortunately, I was right to worry as this 0.5% pure retinol oil was definitely too strong for me and I felt a strong stinging sensation even though I only applied a small amount. It is also possible that I am a bit more sensitive to retinol than others as this 0.5% oil is also marketed to beginner users of retinol so there may be others who can tolerate this better than I can. For those who are sensitive, I’d recommend applying a very small amount using the sandwich method (moisturiser-retinol-moisturiser) and staggering your application to every 3 days.

This oil is amazing. I like retinol. I’m waiting to see the result in 2-3months.

Best best. The smell is strange but I guess it’s retinol’s smell. It’s okay to use. And I’m also waiting for result in 2-3 month….

I bought it for the first time and I loved it. I am really happy that it comes with English directions as to how to use it which really helped. I love how the oil made my skin smooth and firm. I would definitely buy it again

Muy suave no siento ningún molestia muy bien y Perfecto para nuevos

Best for wrinkle and fine line, especially those who start show aging. Use 1-2 times a week is enough

Recently, I received this COSRX Retinol Set from @stylekoreanglobal. I got really excited I promised myself to never ever skip sunscreen. To top the experience, I did the Skin Cycling. I use retinol every 2nd night of my cycle. I'm really glad about it because while I was using the products, I slowly realized how much difference it made to my skin. First of, the Retinol 0.5 oil really improved my skin texture. It gave enough nurishment on my skin without really leaving on a greasy feeling. The Retinol 0.1 Cream also encouraged skin elasticity, prevents acne and fade scarring which you can see on the next photos. Lastly, the Vitamin E Vitalizing Sunscreen was a life saver. It did not only protect my skin from UV rays but also gave moisturizing vitamins on my skin. I really invest my time in every skincare review because I love seeing results. ❤️ Received product last November 3, 2022 Photos are result of The RX Retinol Set in one month use. ✨

I really wanted to like this but it's not for me. the formulation of retinol was too much for my skin for the first time.

It is very nice and give moisture since it has an oil base, helped a lot with my skin Definitly it is a favorite and purchase again

New to retinol. This is a good start. Feels great on my skin and not too high in percentage. Would recommend for beginners.

its good and it working really well for my skin. absolutely love it
