I've only used it for 3 days now with the CosRx bha skin returning emulsion. And my skin feels really smooth. I just had 2 gigantic hormonal acne and i put the cosrx patch on it then this item arrived and used it right away. im not sure if it will help with the healing process since they were pretty much healed already when i started using this but it definitely helped with the scar and other red bumps on my cheeks. of course its only been 3 days so it didnt completely cleared the scar but it did made a difference.
