In my case it didn't work for me at all .only first 2 days I felt a lil difference later it started making my skin dark i tried to apply my sun block along it still didn't work.
May be it's better to use only at night . 2ndly I didn't like the smell it's like very intense chemical though after applying it goes away.
If you are going to try this you better give it a try only for night time as in direct sun light it reverses the effects ( as mentioned on its label) .
