If you’re among those who shave, keeping your skin feeling smooth, silky, and irritation-free has a lot to do with your shaving technique and how you take care of your razor, according to dermatologist Jennifer L. MacGregor, M.D. Here, how to shave a little healthier, every time: This is why Billie’s subscription razor service is about to become your new bff. For as little as $9, the brand will deliver their award-winning razor (starting with two replacement cartridges) and four replacement cartridges thereafter in ongoing shipments once a month, or every two or three months depending on how often you shave. Here’s the genius: Subscribing takes less than 20 seconds (and Billie actually found a way to make it fun!); do it once, and you’ll always have a fresh blade within reach. Replenish your razors on the regular by signing up for Billie today (it’s just $9 with free shipping)!
