What a double-edged sword beauty can be.

Spend your paycheck getting tanned and highlighted — to get that completely natural look. Spend your weekend getting toned and detoxed — and make it look effortless.

Here’s one that won’t add to your to-do list. Certified dentist Hillel Besdin now offers house calls for teeth whitening. (We’re not talking about any Drillman the Dentist stuff. Ew. We hate that as much as you do. Just pure cosmetics here.)

He’ll drop by your house, take a mold of your teeth in about 90 seconds, and leave you with a snazzy little kit containing easy instructions, topical fluorides, and whitening toothpaste.

He’s in and out in under fifteen minutes, he’ll gladly swing by on nights and weekends, and he’ll even come to your office during your lunch hour. All that and he charges less than most in-office sessions: $300 for the first person; $275 for everyone else. (Put the intern at the front of the line.)

Which frees up your time and money for far more important things.

Your hair, for example.

Hillel Besdin, 12 Woodstock Avenue, Brighton (617-738-6500).
