The Gadget: Ionic Pearl Brilliant White Ionic Teeth Whitening System, $195

What It Is:
This at-home teeth whitening device works similarly to the fluoride treatments you get at the dentist's office. Simply squeeze in a tube of the whitening gel, press the activator button on the device (which conveniently times your five-minute application) and place the device in your mouth. The recommended use is five minutes a day, twice a day for five days, with touchups every three months.

What You'll Get:
I have sensitive teeth, so while I do want a whiter smile, I'm not always game to forgo the pain that comes with consuming ice cream and coffee in the weeks after a treatment. With this treatment I didn't feel any increased sensitivity, and I truly noticed a difference after my first five-minute application. With whitening strips I've used in the past, I felt like I had to finish a whole box before I could see some whitening actually happening.

What You'll Save: $400
An in-office teeth whitening treatment can cost upwards of $600, and they aren't permanent solutions either.

The Gadgets: NuFace Mini, $200
StriVectin Facial Toning Device, $200

What It Is:
When you daydream of a toned body, you may not necessarily think about your face, but unlike the muscles on your body, which are attached to bone, your facial muscles are attached to your skin. Meaning as you age, your facial muscles droop, giving you sagging cheeks and jowls. These devices are similar to the electrotherapy treatments found in spas and doctors' offices, and use microcurrents to stimulate your facial tissue.

What You'll Get:
It's safe to say I was terrified to use both of these devices, expecting painful shocks to run through my face. But rest assured, they merely feel like a rubber band snapping against your skin. Although I haven't noticed any major sculpting, my face does feel firmer -- particularly around my jawline. The NuFace only takes five to 20 minutes (I used it for around five each night), five times a week for the first 90 days (with continued use two to three times a week after that). The StriVectin device requires 20 minutes a day, five days a week for 12 weeks. However, the hands-free feature of the StriVectin device (you wear it like a pair of headphones around the back of your neck) did allow me to putz about making dinner and watching Netflix while I toned.

What You'll Save: 5 years*
*At least that's the subjective difference I've seen in before and after photos. Wishful thinking?

The Gadget: Instrumental Beauty Cellulite Massager System, $60

What It Is:
Roll this automated massager over the hips, thighs or abdomen to enhance circulation and reduce the appearance of cellulite. The roller, which operates on one of two frequencies, pulsates over your dimply bits, breaking up the toxins and fat stored beneath the skin.

What You'll Get:
An affordable gadget that promises to get rid of cellulite is hard to believe, but this device has pretty impressive clinical trials (when used in addition to diet and exercise). Nine in ten women reported improved appearance of cellulite and firmer-feeling skin. I've used the device in conjunction with the tube of Advanced Massage Cream for five days in a row now, and although I haven't noticed any major differences in the dimpling on my skin, my skin does feel tighter below my tush. (Note: It did take users about a month to see improvement in their cellulite, where I've only been using the device for two weeks.) My skin's prone to bruising, so I keep the device at its lowest setting, but I think if I can work up to the higher setting, I'll see even further improvement.

What You'll Save: $100
Okay, maybe you're not quite the product guinea pig I am, but that's how much the cellulite creams in my closet added up to. This device works better than all of them.
