Great price for a strong retinol!
I’ve been using this COSRX retinol for about a year now. I love this product. I get compliments on my skin regularly. At a dinner party the other night and someone I didn’t know thought I was her age or younger. Nope! It turns out I was 8 years older then she was, much to her surprise.This product has to be refrigerated after opening. It is very thin (not a negative), so I apply it after washing my face and applying the COSRX Peptide Booster. So third step in face process at night. It absorbs quickly and I like that about it as well. I have some retinols that are thicker (for travel, shelf stable) and they take too long to absorb compared to this one. The strength is high so I have found it to be very effective. There is no scent to it and I’ve had 0 skin reaction issues with this product.I think it has been great at keeping the fine lines at bay, so it is protecting my skins elasticity and helping to keep the moisture in my skin. I will continue to use this product. I always make sure I have an extra one in the frig, so I never run out.I think the price for this product is really good. I have recommended it to several friends and family members who were paying for a high end brand and spending $150.00 for retinol. They no longer use the high priced product and love this one as well. I’m a believer in this product and the COSRX brand. It has yet to disappoint.Pro TiP: if you are new to using a Retinol, I recommend starting out using it every other night and build up to daily. If you have issues, back off how often until you get to the daily stage. It is so worth the effort!

No Regrets for the Price
I love this product. I already heard of this product and its great reviews. Yes it has a thick consistency but blends and absorbs fast. It doesn’t make my skin dry but moisturized, and soft. It is not hard on my skin either. A great investment for my face.

It’s oily, but…
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.This is meant to be the last step in your skincare routine without a moisturizer. I tried three different moisturizers after applying this retinol, but they all pilled. I use the retinol oil as my last step, and my skin feels hydrated, so there was no need for me to apply a moisturizer afterwards.I love that this retinol is powerful but also gentle on my skin. I experienced drying the first time I used this, but I also used it three days in a row. I learned afterward that you need to start slow, and eventually my skin barrier worked itself out. I apply this a few hours before bed so it has time to absorb into my skin. I also apply the COSRX Snail Mucin 96 essence before hand.If you have never used retinol, I would suggest starting with their 0.1% cream and slowly building yourself up to this product.I didn’t experience any skin purging like others have. To avoid or lessen skin purging, I’d recommend using a gentle BHA/AHA cleanser the morning before and after your retinol treatment. Adding this simple step cleared up my skin when I first started using retinol. It expedited the purging process.

Love it
Super moisturizing because it also contains squalene. It’s a great value for the money. I only use it at night because it is a bit oily. Within 5-7 it has absorbed. It comes in a dark glass bottle as well with a dropper which I love. I quality is amazing although I do wish they offered a stronger formula for those of us who is use to retinol. There is no smell which I love. Extremely easy to use. There’s not been a lot of peeling at all but it maybe because I need stronger. As far as results lasting results it has cleared my skin up within one week. It smooths moisturizes & plumps my skin nicely. Four stars because I need a stronger formula PLEASE COSRX

Great Skin Care
My 80yr old mother swears by this! She looks to be about 60 because of retinol and good skin care. She 💯 believes this skin care line is legit and improves wrinkles, skin discoloration and many other skin problems. You must start small and build up over time though.

Okay-ish retinol
Have been using it for about 5 months. Haven’t seen much change. The texture isn’t bad and it barely smells so that’s good! Do have in mind that not every product works for everyone. In this case, it didn’t work for me but I don’t think it’s a bad product.
