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.

Still getting used to it,

Still getting used to it, but seeing some results. Just started it regularly in my skincare routine and was scared to upgrade to this from my other retinol as it might irritate my skin, but this retinol oil is super hydrating and all I need on my retinol night is this, eye serum and all in one cream and I feel hydrated all night.
