With summer nearing its halfway point, New Yorkers may be tempted to rejuvenate their strappy sandal-clad feet with more frequent pedicures. But dermatologists and aestheticians say it’s important to take the season into account — and not to get carried away with foot treatments, no matter how tempting.

Just like with skin and hair regimens, pedicure routines should be altered with the changing weather, experts say. When the mercury rises, and boots are replaced by open-toe footwear, the feet are less protected, so calluses tend to grow faster; when it’s colder and drier, more exfoliation is often needed.

A physician with the Wexler Dermatology Group in Midtown, Francesca Fusco, says people should limit themselves to one pedicure a week. “If someone is getting a pedicure, and there is extreme exfoliation and pushing on the cuticles twice a week, that’s too much,” she said.

During those sessions, the use of an abrasive exfoliant could lead — in rare cases —to over-exfoliation, which could irritate the skin. Dr. Fusco says salon-goers should trust their senses: If the skin becomes red, or begins to hurt, cut back.

Intense foot scrubbing could also cause problems, Dr. Fusco says. “I had a person come in last week, and she had a lot of calluses and asked the pedicurist to really work on it, and it was very tender,” she said, noting that a certain amount of padding is needed. “If you remove all of it, it’s going to hurt and probably that padding is going to reform very quickly.”

Too-frequent treatments could even dehydrate nails. A recent study conducted by Mount Sinai School of Medicine in New York found that people with brittle nails reported using hand moisturizers and getting professional nail treatments more often, leading the researches to conclude that people were either turning to these things to treat their conditions, or the chemicals in the products involved were contributing to the conditions.

The director of product development and operations for Dashing Diva nail salons, Robert Cleary, recommends getting a pedicure at least once a month, but no more than once a week. He said too-thick calluses could impede walking, and necessitate the use of an acidic chemical treatment, which is much harsher on the skin than a pumice stone.

Through August, Dashing Diva salons are offering a “Summer in Capri” pedicure, which features a blue grotto jelly bath, a Limoncello cleansing gel, and a sugar scrub ($65–$75, 41 East 8th Street, between Broadway and University Place, 212-673-9000, and other locations in Manhattan and Brooklyn).

Though a once-a-week pedicure is ideal, those who take good care of their feet by using a moisturizer and a mild exfoliant at home can go up to three weeks between pedicures, the director of La Prairie at the Ritz-Carlton Spa, Sandra Sadowski, said.

So what should customers expect when going for a pedicure?

“You want to start off with a foot bath to loosen the dead skin and to hydrate,” Ms. Sadowski said, noting that her spa offers a 75-minute Silver Rain pedicure with a hot stone massage on the feet and calves ($100, 50 Central Park South, 212-308-9100). “The nail technician will look at the condition of your feet. Then, you and the technician can decide on which pedicure is best because, really, a pedicure is a facial for the foot. It’s skin, and we should be treating the skin just as we treat the skin on our face.”
