I am absolutely in love
I am absolutely in love with this retinol oil! It absorbs wonderfully, doesn't dry out the skin, and leaves my face smooth, glowing, and visibly firmer after just a few weeks of use. The oil base makes application so smooth and luxurious. Will definitely buy again!

Customer review from cosrx
Excellent, I love this product
It is an excellent product that does not irritate the skin, it absorbs properly and penetrates the layers of the skin providing a texture and stability of the skin
Title: Great results, just needs patience
This is my first retinol and I appreciate how COSRX made it beginner-friendly. The oil texture is lightweight and helps buffer the retinol, so I had minimal dryness. Took about a month to see real improvement in my skin tone and firmness. Only reason for 4 stars is the dropper bottle - it can get a bit messy. Overall solid product for the price and perfect if you’re new to retinol.

I like the gentle way
I like the gentle way of that retinol working. My skin has never had irritation during using that product. I use it twice a week, in the morning use VitaminE Sunscreen and I like the effect. I have oily skin with acne, post-acne dark spots. As it’s written in the instruction, I keep the bottle in the fridge.
