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: Real Results for Mature Skin Without Usual Retinol Irritation. - Real results! I have tried every serum under the sun!

But now I don’t even notice at all. ### ⭐⭐⭐⭐⭐ Great retinol!!! *by C***D on July 12, 2026* Previosuly, I was using COSRX Retinol 0.1 , so I decided to give a try a more concentrated retinol, and it's amazing product. I have been using it for more than a month 3 times per week. I felt my skin a little bit drier the next day, so I put on top some moisturizer. That dry effect was gone after week 2. By now, I just applied the retinol and my skin the next day looks so healthly and beautiful, I think it's helping with some small wrinkles and dark spots on my forehead. It has a oily texture, but I dont feel greasy. I think It's a good price for the concentration and amount. I wish I didn't have to storage it on my fridge though. ## Frequently Bought Together - COSRX Retinol 0.5 Oil, Anti-aging Serum with 0.5% Retinoid Treatment for Face, Reduce Wrinkles, Fine Lines, & Signs of Aging, Gentle Skincare for Day & Night, Not Tested on Animals, Korean Skincare - COSRX Snail Mucin 92% Face Moisturizer, 3.52 Oz, Lightweight Moisturing Cream for Soft, Glowy Skin, Korean Skin Care, Korean Moisturizer Face Cream --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/463909114-cosrx-retinol-0-5-oil-anti-aging-serum-fine-lines](https://www.desertcart.hr/products/463909114-cosrx-retinol-0-5-oil-anti-aging-serum-fine-lines) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-09*
