Serendia is the leading developer of new technologies that target every aspect of your lifestyle. We specialize in skin technology that provides real solutions to real problems. Our first product, the Scarlet SRF, is pioneering the path for safe and effective radio frequency treatments.

Scarlet SRF

A revolutionary solution for safe short radio frequency skin treatments.

Scarlet SRF is the safest treatment in the field of RF systems, with absolutely no down time. It targets virtually any skin issue. Clients are good to go immediately after treatment; there is no bleeding or sensitivity as experienced with other microneedle treatments.

Developed by the researcher behind the Na Effect, Scarlet SRF is the first and original short pulse microneedling RF treatment using the phenomenon of alternating bipolar signal energy. First published in Scientific Reports, a journal of the Nature Publishing Group, the technology behind the Scarlet SRF is guaranteed safe and is FDA approved. The Scarlet SRF is patented not only in America, but in 70 other countries, in Europe, Asia, Middle East, Oceania, and South America.

Na effect

• Previously discovered radio frequency treatments were either ineffective or unsafe, with short-lived and limited results.

• However, through a study published in Nature Publishing Group’s Scientific Reports, renowned doctor and scientist Jongju Na was able to find the key method for the safest and most effective RF treatment. He named this discovery the “Na effect”.

• The distinguishing factor of this phenomenon is the achievement of independent tissue coagulation around each microneedle electrode. While previous RF systems were only able to produce a widespread area of coagulation around the whole area of skin targeted, leading to an ineffective treatment with little to no results, the Na Effect allows for incredible skin rejuvenation.

• The proven science behind the Na effect is what allows the Scarlet SRF to deliver state-of-the-art care and healing for people of all skin types and issues.

• “Nevertheless, the emission of RF energy for more than 1 second produced a cocoon-shaped area of coagulation around each microneedle electrode which is the area with higher current density, and then convergent areas of coagulation in the areas with lower current density between the microneedles as inter-electrode currents passed between electrodes: we suggest naming our novel finding of independent tissue coagulation around each electrode as a “Na effect” to distinguish it from other RF tissue reactions.”
