Worst smell ever
Smells horrible. I can’t even blame the DHA because I have used Devoted Creations body moisturizer with DHA and it smelled wonderful. I used this once and threw it out.

Hmmmmmm
Omg the smell of the one with the gradual tanner is 100% that fake tanner smell. I’ll let you know how it works and if it transfers onto anything it’s not supposed to but I have all white sheets so we will see! If it works and doesn’t transfer it might be worth it if I top it with a body oil that smells amazing
