Abstract:
Fractional bipolar radiofrequency technology is associated with minimal downtime and rare side effects and become an increasingly popular tool in aesthetic dermatology practices. There is limited damage to the epidermis, and side effects such as post-inflammatory hypo/hyperpigmentation are rare. Transient erythema, edema, crusting, and persistent inflammatory papules have been previously reported. We report a rare case of sterile follicular pustulosis following treatment with bipolar fractional radiofrequency (eTwo technology). To the best of our knowledge, this unusual side effect has never been reported.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
