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

I am a fan of COSRX product. I have tried almost all of their product, so i was excited when they released retinol. I've been using The Ordinary retinol for a while and i find it quite heavy and oily on my skin. So when i got hold of the COSRX retinol, the first thing i noticed was the smell, i didnt like it, though i find COSRX retinol better than The Ordinary. It absorbs faster, lighter and i could see the lines faded faster. Aside from the smell, i wish they could create a cream based that is .5 since i worked on night shift, i put retinol before going to work and i had put extra time to make sure it absorbs on my skin before i go out. All in all, the price is good, i see improvement in my skin and i would definitely buy this since this is better than the Ordinary retinol.

I’ve been notice some changes on my neck after using this for a month, my fine lines seems less appealing and doesn’t give me a break out either on my face or my neck where my skin is even more sensitive then my face. i use this after moisturizer. Overall, this is a great product, the smell is abit off but it’s effectiveness is great.

Súper genial y efectivo su olor es a caña de azúcar por el aceite squalane muy suave no me irrito

Recommend combining with The Retinol 0.1 Cream for the best result. A facial oil infused with 0.5% retinol to replenish your skin. I've used much stronger but this gives good effects without drying out your skin. It improved my skin a lot, especially my pores and blackheads. My only remark is having to store this in the fridge. Please do your research before using retinol.

This is a good retinol for those who are new to it. I've used much stronger but this gives good effects without drying out your skin. It is good at evening skin tone and reducing pores but need to use for longer to see how it goes with wrinkled

Have just bought it haven’t tried it yet

La textura es muy buena, resultados en poco tiempo

This tingles but I think it's good. Please do your research before using retinol. Thanks guys!

Just started trialing adding retinols into my skincare routine and since this is an oil formulation it’s not irritation or drying at all

This serum good for night route.Just a few drop is enough. if you just start using it, should apply another. After using this i noticed that my skin become glowing and smooth.

I bought this for a customer so I can’t say whether it’s good nor bad

It’s one of my favorite product

My friend recommended this for me and now I love this product with affordable price and high quality. I would like to recommend this to everyone out there. When on next sale I will definitely purchase again really worth the price. Especially anyone who have sensitive skin like me can be use too. Don’t miss the good one !!

I've been using this product 2-3 times only and I have no problem with it so far. The texture is lightweight and since I used it before sleep, it does provide some hydration during the night.
