how do bath bombs work? 

Do know how do bath bombs work?  Do you put the bath bomb in before you get in? While it's often debated which comes first, Vega says that dropping your bomb into a full tub is what lets it dissolve properly, unleashing all its lovely ingredients in the process. So wait for your tub to fill up, then add your favorite bath bomb or oil.

Once dissolved in water, bath bombs release citric acid which fizzes up and helps loosen damaged layers of skin. The oils in bath bombs also tend to be super moisturizing, and basking in a tub of hydrating oils will leave your skin feeling soft and supple.
