Acne sucks. But the scars acne leaves behind suck even worse -- can't spackle over them with concealer, and they never, ever go away.

Or do they?

A new technology called Sublative Skin Resurfacing shows mind-boggling results. (Take a look at these before and afters. Ah-mazing.) It's a radio-frequency device that uses heat energy to "injure" the dermis (layer of tissue underneath your outer skin), making it produce more collagen. Unlike lasers, radio frequency can be used on all skin colors. Plus, there's minimal downtime. You'll be pink for a day or two -- that's it -- and it barely hurts.

Price will vary from doctor to doctor, but you're looking at about $250 a pop. Three treatments deliver the best results, but you'll see a difference after one or two.

In the grand scheme of great inventions, this one's somewhere between Spanx and cruise control. What do you think?
