It works well and exfoliates gently , for example i had a spot on my chin and used this serum for the first time at night all over face and neck followed by rambutan lotus moisturiser - the next morning the spot scab fell off. It’s extremely gentle and also has a cooling effect on me. Its the first time using ceylon spa products so will update in a few more weeks of use. Also there’s no scar from the spot ! I bought it primarily because i wanted a product with arnica in it and this has arnica in it which is great for puffiness and swelling. Wish there was a toner .
