The first thing I noticed when I opened this product was that it had a HORRIBLE SCENT. It was sour and smelled like vomit. I contacted Jolse about this and we sorted things out, but I ended up keeping the product and testing it on some areas. It seemed to help lighten a scar on my leg and the scent smelled better, like oranges after a few days so I tried it on my face. It's super sticky, so be warned. But it does work and my skin tone was noticeably more even and clear within two weeks. Make sure you don't exfoliate before using this or else it's going to burn and sting! Also I only use it at night because I'm afraid it would react with the sun if I use it during the day. Overall it really does work, but I don't like having to change my skincare routine around it due to the ingredients and stickiness.
