Radiofrequency can be effective in treating shallow acne scars. This treatment method uses fractional radiofrequency to stimulate dermal collage and encourage the skin to rejuvenate. RF therapy uses radio wave beams to heat the subcutaneous tissue. The high frequency radio waves are at ~5MHz and they are absorbed by the tissue in the target area. Most systems have a built-in coolant to spray the treated area with cold gas. This way, the surface does not have to heat to a similar degree as the internal tissue.
Radiofrequency therapy may have two effects on pimples. First, the increased temperature works to kill the bacteria in the acne to minimise inflammation. Second, RF may decrease the activity and size of sebaceous glands to reduce the production sebum, which is one of the causes of acne. RF therapy has been studied for efficacy in treating acne and researchers found significant improvements on patients who have used it to get rid of pimples. However, it is noteworthy to consider that RF therapy is not widely available and are offered only by select dermatologists for pimple treatments and removal of acne scars.
Radiofrequency therapy is administered in select dermatology clinics, spas, hospitals, and cosmetic surgery centres. The cost for treatment varies per application, the type of system used, and the area that is being treated. Some dermatologists may administer RF therapy with other topical acne treatments for best results. This way, inflammation can be managed continuously and bacterial infection can be minimised.
The treatment is gentle and causes little to no downtime at all. RF may be used as sole treatment for acne scars or with a laser treatment method to ensure best results. Unlike conventional lasers, RF is less damaging to the skin due to the gentle radiowaves that heat the inner layers of the skin. Fractional RF treatment may require three to five treatments for optimal results. You might experience skin redness for 12 to 36 hours after treatment, but it will gradually fade. RF is considered to be safe for all skin types and can be combined with acne treatments that use roaccutane.
