Great expectations: the truth about cosmetic dermatology

Procedure: Chemical Peel

What it is: To reduce acne and boost radiance, dermatologists brush on acid blends—AHAs, salicylic, lactic and glycolic are the most common—wait a few minutes, and then neutralize.

The cost: Around $150–350 each, and you'll begin to see results after one session. Four to six sessions spaced two to four weeks apart will deliver a clearer, more even complexion.

Editor's take: "I've had gentle peels that immediately made me look glowy—but the effect only lasted 48 hours. After a stronger peel, I started shedding a day later and didn't stop for four days. I was disgusting at first, but a week later people were complimenting my dewy skin."

Insider's intel: "Plan a deeper peel before a long, lazy weekend—you'll want to spare others from the shedding process. Also, use heavy sunscreen for weeks afterward. I ended up getting sunspots on my freshly peeled skin."

Faking it: A month of the at-home Dr. Dennis Gross Skincare Alpha Beta Peel gives the results of one in-office experience.
