Who should do it: "The best candidate for Cellfina has what I call 'dimpled cellulite,' rather than long ridges, wavy and uneven skin or sagging," says Michael S. Kaminer, MD, Associate Clinical Professor of Dermatology at Yale Medical School and Assistant Professor of Dermatology at Brown and Dartmouth Medical Schools. These dimples respond best to the treatment and, as luck would have it, are an extremely prevalent type of cellulite, especially on the thighs and butt.

Why you should do it: Not-so-fun fact: More than 80 percent of women over the age of 20 will develop cellulite at some point (regardless of weight), says Kaminer. Exercise and diet can help with cellulite, but only to a certain point -- and even procedures like lipsuction have no impact on cellulite whatsoever. Enter: The magical Cellfina System. "It's the only FDA-cleared minimally invasive procedure clinically proven to produce long term improvement in the appearance of cellulite," explains Kaminer, who reports that his patients are ecstatic with the results. "Patient satisfaction with Cellfina far surpasses that of any new treatment I have seen come to market in the past decade."

Some numbers to back that up: After three months, 85 percent of patients in the FDA-approved study were satisfied; after one year, that stat increased to 94 percent; after two years, patient satisfaction was up to 96 percent, which Kaminer calls a "staggering" number. In a single treatment, the appearance of cellulite is greatly reduced. And the procedure itself is minimally invasive. The surgeon marks the areas to be treated, then they numb the area. "Finally, we use a specialized hand piece to precisely access tissue where we can release the cellulite-causing bands," Kaminer explains.

"It seems that as patients heal from the initial procedure, their skin seems to get smoother and smoother," he explains. "Recovery is just a couple of days, but the remodeling of skin takes some time to see the final result. The beauty of this is that once the skin is remodeled, it seems to look better and better over time, and this likely leads to the longevity of the results we are seeing."

Know before you go: You'll want to lay low for a couple of days post-procedure (you can still go to work, but wait four to seven days to resume exercising). You may experience some initial soreness and tenderness, but it doesn't last for long. Before the procedure, Kaminer says to avoid anything that may cause bruising, like vitamin E and fish oil supplements, or medications like Advil and Motrin. Oh, and wear loose-fitting clothes to the appointment. After your treatment, they'll squeeze you into a compression garment before you leave. Kaminer tells his patients to buy a couple pairs of Spanx, as well, and wear them all day, every day for a week. Yeah, that sounds kind of annoying, but it helps speed up the healing process and helps you see even smoother results.

Cost $350 per 30 minute laser session; $400-$900 per injection.
Lasts: While spider veins will disappear, eventually touch ups are needed.
Who should do it: Anyone looking to get rid of spider veins and smaller varicose veins.

Why you should do it: Rebecca Kazin, MD, of the Washington Institute of Dermatologic Laser Surgery and the Johns Hopkins Department of Dermatology, says that you can see significant results with just one session of injections into the veins, called sclerotherapy. If spider veins are more prominent, she says some patients will opt for three treatments spaced six to eight weeks apart. Treatment is only mildly uncomfortable, and feels like little pin pricks.

Know before you go: Veins will actually look worse before they look better, says Kazin. The veins can turn red from the treatment and look a little hive-like. "The veins can look darker before they get lighter because the veins collapse over the blood," she explains as another side effect. Downside: It takes four to six weeks to look normal again. Upside: You can resume regular activity the next day.

Who should do it: "If you are looking to make hair more low maintenance, to cut down on your blow-dry time and also want your style to last longer in humidity, then you are a good candidate for a treatment," says Butterfly Studio Salon master stylist Nicole Descoteaux.

Why you should do it: Skip the stick-straight hair you'd get from a Brazilian Blowout and instead opt for a gentler option that leaves your hair frizz-free, but with bounce and body. "As women, we like to care for ourselves and our appearance, but we also want it to be practical and easy," says Descoteaux. "These treatments relieve the frustration from time-consuming styling that will not last in humid climates." It's also a great way to try out a new haircut you may normally shy away from. "Many people, because of their texture, cannot entertain a new on-trend shorter look. So by altering the texture first, it opens new opportunities for them," she explains.

One such treatment is the DeFrizz Quick Treatment, available at Julien Farel Salon in New York. "I created this anti-frizz treatment because so many of my clients wanted a healthier alternative to straightening," says Rudy Pena. It's a 90 minute in-salon treatment that Julien Farel describes as "superfood for your hair, because it features natural oils like grape seed, sweet almond and jojoba."

Descoteaux says formaldehyde-free options are the way to go, because they are healthy options that make your hair healthier. She likes Cezanne Perfect Finish Smoothing Treatment. It's keratin-based and also includes glycolic acid and sericin, so it smooths from the inside out -- as opposed to typical formaldehyde formulas, which just coat the hair to give it a smoothing effect.

Know before you go: Upkeep can get spendy, and it's important to do your research before you go. Look for salons that offer non-formaldehyde formulas, and make sure you get an experienced technician.

Cost: Typically, a small area like the upper lip will cost approximately $100-$200 per treatment, while larger areas like legs can range from $350-$900 per treatment.
Lasts: Long-term, nearly permanent. "Patients may have a new area of re-growth that occurs years after their hair removal sessions have ended," explains Julius Few, MD, director of the Few Institute for Aesthetic Plastic Surgery and Clinical Professor at the University of Chicago. "However, the average patient can expect 80 percent plus permanent hair loss."
Who should do it: "The ideal patient is fair-skinned with coarse, dark hair," says Kazin. People with white, light blonde or red hair on their bodies are not good candidates because the laser can't detect the pigment.

Why you should do it: Hate shaving and waxing? This one is for you (as long as you fit the above requirements). You can get the treatment done essentially anywhere you have hair -- legs, face, bikini area and underarms to name a few -- and the time ranges from a few minutes for a small area to 15 minutes for a larger area. There's slight pain -- think of the pain from being waxed or having your brows plucked, says Kazim -- but typically a topical numbing cream or a cooling mechanism is used to decrease discomfort. Know before you go: Because of your body's hair cycle, you can only reduce the amount of hair by around 20 percent each treatment, says Kazin. It can take 5-6 sessions to get rid of hair completely. The area will be pink and sore for about a day, and if you have a darker complexion you have to be incredibly careful about sun exposure, as it can turn the area brown, explains Kazin.

Cost: $700 a syringe; $3,000-4,000 for ultrasound therapy
Lasts: 6 months to one year
Who should do it: Someone who wants plastic surgery in theory, but doesn't want to go under the knife (or end up looking like a guest on "Botched.")

Why you should get it: Gabriel Chiu, DO, celebrity plastic surgeon in Beverly Hills, says one thing that's extremely recession-proof is Botox. But not just to erase frown lines. More and more people are using injectables for "temporary, long-lasting" nose jobs, cheek lifts, and jawline augmentations.

Recently, other types of therapies are being approved for use in ways that can mimic plastic surgery. Ultherapy, which uses ultrasound therapy, was recently FDA cleared for the neck and décolletage area. Ulysses H. Scarpidis, MD, Board Certified plastic surgeon and member of ASPS and ASAPs says, "Ultherapy is the only non-invasive technique that directly tightens the underlying muscles of the face, much like a facelift, albeit to a lesser degree." He adds that patients who need a small lift, or who don't have the luxury of a long recovery required with traditional surgery, will very much benefit from the results. Plus: no downtime. Manhattan-based Dr. Arash Akhavan adds that the collagen generated by the procedure is permanent -- but since your face, neck and décolleté will continue to age patients will likely need touch ups every one to five years, depending on their sun exposure and genetic background.

Know before you go: Dr. Antoinette Notaro adds, while fillers can results in an improvement that's satisfactory for someone who doesn't want to undergo surgery, they won't be as permanent or as drastic as a surgical intervention. The main difference (aside from the whole scalpel thing): "Surgery will pull the skin; filler gives it three dimensional fullness." The results are subtle, and you constantly need to get touchups to maintain the results.
