Dip Powder
Dip powder nails are somewhere between a regular mani and a fake nail. We can consider them a "diet acrylic," says celebrity manicurist Erica Marton. Instead of using UV rays to seal in your polish, the color comes from a pigmented powder. Between base coats and a sealant, you dip your nails into a little jar of your chosen color for a mani that could last two weeks. The trend isn't exactly new per se—it's actually been around for years—but the wonderful world of social media is quickly popularizing the process and helping it stage a comeback.
Watch the dipping in action—it's one of those beauty hacks we can't take our eyes off. (I'm worried that the nail dip is my new bun drop.) Warning: If you have this done at a salon, you won't get to dip. A nail technician should paint the powder onto your nails to keep things hygienic between customers.
