  • Works like a charm
Size: 0.67 Fl Oz (Pack of 1)
I love this retinol serum however be aware it's concentration is higher than others so a little goes a long way. I never had any skin irritation or any issues when applying it in my regular skincare routine. However it's advised not to use retinol every day or when scrubbing your face. It's very lightweight and your skin is able to absorb it nicely so it won't leave your face oily. I noticed that if you don't keep it in the fridge that the color of the serum may change to a darker color due to oxidation so best to keep it in a regular fridge. ... show more

  • Hydrating.
Size: 0.67 Fl Oz (Pack of 1)
I enjoy this product because of its benefits of retinol and the oil that it is in is very hydrating and a bottle lasts for a very long time. I believe I will be using this product for the rest of my days. It’s a staple in my nightly routine. It’s a very good product to prime your skin, making it easy for other products to glide on your face. A little goes a long way. ... show more

  • Gives plump
Size: 0.67 Fl Oz (Pack of 1)
The media could not be loaded. Ladies, look no further for your new retinol bestie. Scentless, moisturizing repairs and dryness and leaves smooth skin behind. I do notice this is the oiliest of retinols I’ve ever used but I actually love it. Paired last before my moisturizer I feel like it feel soaks into my skin and helps repair those super fine lines. There is no stickiness to it at all though it will glide perfectly onto your skin and absorb. 10/10 I’ve repurchased now twice. Also get the morning cousin - vitamin C! ... show more

  • Worth it!
Size: 0.67 Fl Oz (Pack of 1)
This is an oily retinol which is best used at night. I use the pipette to place 1 drop on each of my finger pads ( 4 drops total, anything more is a slick mess) and pat on my face and neck. No stinging, flaking, burning, or irritation. I did notice some pigmentation come to the surface, so i know cell turnover is happening. The scent is not pleasant but it doesnt smell bad either. I am glad to have found the product, and it is worth the money! ... show more

  • Use religiously!
Size: 0.67 Fl Oz (Pack of 1)
I love this stuff. I want to think it’s working as my skin feels great now. I’m 44 and getting signs of fine lines around my eye area. It didn’t burn me up too bad maybe caused some dryness but that’s to be expected. Just use some heavy moisturizer. Great piece for a great product.

  • Effective and gentle
Size: 0.67 Fl Oz (Pack of 1)
I absolutely love this retinol serum. It is very gentle on my sensitive, rosacea skin. After just a couple of weeks I started using it every night and I have gotten so many compliments. I have used retinol products before that were too harsh and this one was perfect from the very first use. Will likely upgrade to the 1% over the next few months. Honestly the entire COSRX line is fantastic. ... show more

  • Oily
Size: 0.67 Fl Oz (Pack of 1)
It's oily. I must of missed that when doing research on retinol. It also has a smell. Kinda rancid. Hoping it's not old? Idk I like my old retinol better.

  • nice, mild retinol oil
Size: 0.67 Fl Oz (Pack of 1)
Very nice retinol oil; light texture, easily spreadable, soaks right into my skin. No scent whatsoever. This company does recommend that you keep it in the refrigerator or a cosmetic chiller to maintain efficacy. This is typical for retinol products. At the very least, store it somewhere dark and cool. Don't store it in direct sunlight or close to a heating vent. ... show more
