A bath bomb gives your average at-home soak an unrivaled upgrade. If you dare to bathe without one, reconsider -- just pop one of these fizzy, fragrant bath accessories in your tub and it'll instantly fill the water with delicious scents and vivid colors. Um, magical.

Though dermatologist Dr. Barney Kenet, MD, points out that bath bombs aren't actually magical. "The main ingredient is basically baking soda," he says. Like an Alka-Seltzer tablet -- that's what causes all the fizz. (We're still holding out for unicorns and calorie-free ice cream).

Still, a bath bomb can do magical things for the skin -- with one caveat. "They offer essential oils and scents, which can be very moisturizing and soothing," says dermatologist Dr. Debra Jaliman, MD. However, their fragrances and dyes may be too much for some. "People with extremely sensitive skin like eczema or allergies may want to stay away," she warns.

With bath bombs, it's mostly about the sensory experience. "Their fragrances can affect mood, sleep and libido," explains Kenet. "And the fizz can certainly feel sensual."
