This week’s Shark Tank features an ingenious device — the Sunscreenr, which helps you check if you’ve covered yourself properly in sunscreen.
The $119 product allows you to look through a viewfinder at skin and see if there are any areas where you’ve missed a spot.
It will also highlight parts of your body where the sunscreen you applied earlier in the day has worn off and isn’t protecting you any more.
For example it may no longer be effective after you’ve been swimming, sweated the lotion off your skin, or used a towel.
The device, invented by biochemist Dave Cohen, can help protect against skin cancer by allowing you to make sure you and your family and friends are all lotioned up.
Cohen had already raised $285,000 of funding through crowd-funding campaigns on Kickstarter and Indiegogo before appearing on Shark Tank.
You can pre-order a Sunscreenr for $119 on the firm’s website.
