A bikini wax is a summer must-have for many of us — but it often comes with a side of pain. Leave it to an anesthesiologist to come up with a fix. Edna Ma, MD, brought her BareEase Prep Kit, $10, on a 2013 "Shark Tank" episode, explaining that the cream works by temporarily numbing skin with lidocaine so that you can wax to your heart's content without the discomfort. The kit also comes with a latex panty that helps the cream absorb.

Cutting your own hair sounds like a recipe for disaster, but not so with CreaProducts' innovative CreaClip, $23.44. Appearing on a 2016 episode of "Shark Tank," inventor Mai Lieu showed how her hair tool could be used to DIY a haircut with ease. Snap on the tool (there's one for bangs and one for the rest of your hair) and snip off the excess for an even cut — it really is that simple.

One of the easiest ways to showcase your personality is by rocking a bold lip — and The Lip Bar Lipsticks, $12, come in a whole host of can't-look-away shades. What sets these lip colors apart is that they're infused with nourishing ingredients like vitamin E oil, avocado oil, shea butter and coconut oil, as creator Melissa Butler told investors on a 2015 episode of Shark Tank.

Medical esthetician Lydia Evans shared her patented 3-in-1 Sw&g Bar, $16.99, on a 2014 episode. This handy-dandy product cleanses, exfoliates and soothes. It's particularly useful when used after shaving or waxing since it prevents ingrown hairs and calms irritation.
