At home: Though you'll probably be the only one to notice a difference, you can temporarily diminish that upholstered-cushion look with a cream or gel containing caffeine, which enhances blood flow and briefly decreases swelling, says Tina Alster, MD, clinical professor of dermatology at Georgetown University Medical Center.

At-home essential: Perricone MD Cold Plasma Body ($110; perriconemd.com)

In office: Cellfina

How it works: After injecting local anesthesia into the affected area, the doctor uses a handheld device to suction the skin and then slides in a needle to break the fibrous bands that cause dimples, says Ava Shamban, MD, assistant clinical professor of dermatology at the David Geffen School of Medicine at UCLA. Results are apparent in three days and can last up to two years.

Number of treatments: one

Average cost: $3,500 to $5,500
