The Retinol 0.5 Oil

A user in a hot climate who blots off the COSRX Retinol 0.5 Oil after an hour says it works slowly but their skin improves, with no reaction at all.

“Personally the retinol does work slowly, I have no reaction whatsoever, my skin does improve”

A user who stepped up from a 0.1% retinol to the COSRX Retinol 0.5 Oil was happy with it and used it every night before looking for a stronger option.

“After using the 0.1% from Some by Mi, I switched to the 0.5% retinol from Cosrx. I was happy with it, I use it every night”

A user moving up to the COSRX Retinol 0.5 Oil got breakouts in congested areas after two days and suspects the squalane in it rather than a retinol purge.

“So, after two days, I have some purging or breakouts, I'm not sure which.”

An oily, acne-prone user who built up to daily use of the COSRX Retinol 0.5 Oil started breaking out badly after six weeks and is almost certain the oil is the cause.

“Recently I started breaking out really bad, it has been a month and a half of me using this product so I didn’t expect it.”

A dry-skinned user who worked up to the COSRX Retinol 0.5 Oil over 18 months finds it super hydrating, has seen fewer fine lines and had no irritation or purging, and now wants something stronger.

“It's super hydrating which I love because I have dry skin, and I do notice a reduction of some fine lines whenever I manage to not sleep on my face lol.”
