This is the updated version of Cosrx retinol in a base of squalane. It's really good for beginners just getting into retinoids and quite gentle. The chubby bottle is also really cute and unique. The only downside is it needs to be stored in the fridge and sometimes that makes me forget to use it.

I love the packaging. It's very sophisticated with instructions on how to use it. I didn't have the retinol cream so I mixed it with my Dr.Jart sleeping mask and applied it 1-2 a week. I noticed my skin feeling more plump and has increased in elasticity. I also see a bit of glow however, I didn't notice any moisture retention as my skin still felt a bit dry in the coming days after using it. Can't wait to see what this product will do for my face after a longer use.

*Packaging : nice *Quantity :20ml *Texture : oil type *Smell : weird After use this product first time I use this product I it not that quick absorb as water type serum and spend time to massage and taps for absorption. And in the morning my skin felt plum and moisture. For the wrinkles and fine line area I didn’t see much improvement maybe I have to apply it for a month to see the good results

My mom, who is in her 60s loves this oil. She uses it as a single product for her night routine and mentioned that her skin improved significantly. Less dryness and skin is brighter. Will buy it again for her. #readysetglow #rsg #stylekorean_rsg #readysetglow_oct

It was nice for glowing and smooth face

because the oil texture, it so moisturing! didn't give tingling feeling even for the first time

I love all the product from Stylekorean. They provide only the authentic products to customers. I can say Stylekorean is the most trustful website for everyone who is interested in Korean cosmetics. all the product from Stylekorean. They provide only the authentic products to customers.

The oil formula helps with emolience to keep the skin from gettting dry spots. So far mild enough and doesn't cause irritation. Watch out for those with peanut allergies though. This stuff has peanut oil in the ingredient list.

Looking good, worth the price, best recommended retinol, good package

Amazing product if you have dry dull skin.

Cosrx never disappointed their customer. Feel my skin smooth and brightening after use a few days. Anyway, I quite like it.

Just a few drop is enough! The texture is easy to absorb. Now wait for long long term use results.

This serum good for night time. Just a few drop is enough. After using this i noticed that my skin become glowing and smooth. It’s easy to absorb as well.

good product not regret purchasing at all. love it

I want to include retinol product to my skincare routine and Im glad that Cosrx has this retinol product in oil form. I think it is best for sensitive and dry skin because the oil makes the retinol product is so much softer on the skin. It doesnt irrite sensitive dry skin like regular retinol products. I love it so far and have great hopes from this product. Recommend.
