There are so many treatments and devices out there that claim to tighten, reduce fine lines and wrinkles, and rejuvenate your skin, but there are at least a few that dermatologists and aestheticians actually back. One of them is radio frequency -- a skin treatment designed to give you a noticeable lift and renew your inner radiance. While in-office treatments can be done and are great for those that can afford them, radio frequency is also offered in a variety of quality at-home devices, making it pretty accessible. And unlike more aggressive laser treatments, radio frequency doesn't require downtime!

If this sounds good to you, you're going to want to keep reading. I asked a board-certified dermatologist and aesthetician for everything we need to know about radio frequency skin treatments and the best at-home devices.

Master organic aesthetician Katie Sobelman breaks down exactly what radio frequency is for those who might be unfamiliar. "Radio frequency is a safe cosmetic treatment that uses energy waves (in the form of radio waves) to create a gentle low level heat," she explains. "This heat penetrates into the deeper layers of the skin, three milimeters down, activating collagen and elastic formation, to firm the skin. RF can be used to not just tighten the skin, but to minimize fine lines, and improve skin tone and texture."

Board-certified dermatologist Brendan Camp, MD, FAAD, explains further that radio frequency creates micro-injuries deep within the tissue of the skin which then, in turn, trigger a reparative process that stimulates new production of collagen and elastin. Although the sound of "micro-injuries" might not sound totally appealing, it's almost similar to other reparative treatments like microneedling which operates in a similar matter. It can improve the overall quality and texture of your skin in a big way.

Camp also mentions that radio frequency offers an advantage over certain laser treatments. "One of the limitations of lasers is that they may not be appropriate to use on all skin types because of the risk of discoloration or scarring," he says. Instead, Camp champions treatments that offer a combination of modalities like radio frequency microneedling. He continues, "Radiofrequency microneedling is an equal opportunity treatment as it can be used on all skin types."

Additionally, Camp says that radio frequency can be used to treat acne scarring and can even help reduce the appearance of blemishes. It should be noted, however, that if you're dealing with skin barrier damage, inflammation, breakouts, and sensitivity, proceed with caution when it comes to getting a radio frequency skin treatment. Heating the skin too often could potentially cause more inflammation or trigger new breakouts. Start slow and see how your skin reacts.

Radio frequency can benefits people of all ages, but it is most beneficial for folks in their 20s, 30s, and beyond. Like I mentioned above, radio frequency can be used to tighten, firm, and rejuvenate the skin. This may appeal most to folks in their 30s and beyond, but like I previously mentioned, radio frequency is also great for acne scarring and hyperpigmentation.

According to Camp, any potential side effects of this treatment depend on the type of radio frequency skin treatment you're receiving. "The risks and side effects associated with radiofrequency depend on the type of treatment because radio frequency is available in a number of different platforms. Radiofrequency microneedling (RFM) is one of the most common. Patients undergoing RFM may experience pinpoint bleeding, redness, swelling, bruising, pain, and temporary skin discoloration."

If done incorrectly, radio frequency treatments could potentially cause unintended fat loss in the face so be extra careful, do your research, and consult with an expert before getting a treatment. This can happen due to excessive overheating of the skin or heating the wrong layers. It can also occur if you do the treatment too often. It's a good idea to consult with a dermatologist before starting treatments like this to make sure it's right for your skin and to help you get a better idea of how often you should do it.

There are various forms of radio frequency. The best and safest option for home use is multi-polar radio frequency as it does not penetrate deep enough to affect adipose tissue.

That being said, both Camp and Sobelman have a few at-home devices they love and recommend. At-home devices are definitely pricy, but are great to have handy and can provide many long term benefits if getting in-office treatments all the time isn't fully in your budget. You can check them out below.
