Review: 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!
Review: Perfect strength for retinol without harshness. - This serum works wonders! My skin feels smoother and more radiant every day. Perfect strength for retinol without harshness. I’ll keep repurchasing!

### ⭐⭐⭐⭐⭐ Great Skin Care
*by M***A on January 1, 2026*

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.
