I m using this serum from 20 days now, and it's nice but don't expect any miracle. Maybe it will take more time, but yeah, it does gives you a rejuvenated skin. I m using it daily twice in my day and night time cleansing routine, along with biotique honey gel face wash, followed by honey water toner, then this serum and then morning nectar mosuriser. So whether it is the serum or the complete skincare regime that is giving healthy looking bright skin. But yeah, its all noo chemicals products and best to be used daily. And serum is good at such a price. A little amount is reqired for whole face and neck.
