The frequency of the device was another important parameter. “A slow frequency resulted in low absorption and a fast frequency did not feel good on the skin,” Akridge explained. The team therefore utilized a sonic frequency, the frequency at which audible sound frequency is converted to mechanical energy, and discovered that 125 Hz yielded the best level of product absorption.
In addition to the device, Akridge’s team developed a serum using several marine-derived materials such as collagen to increase skin moisture and restore tissue fullness, glycosaminoglycans and elastin to firm and tighten the skin, and acetyl citrull amido arginine, a marine peptide, for its antioxidant protection. Additionally, botanicals chosen included: prickly pear extract and trehalose to hydrate the skin; African sausage tree fruit extract to firm the skin; and, for their antioxidant protection, Canadian willow herb and oat kernel extract. According to Akridge, he choose several ingredients that do the same thing for a reason. “I wanted to take a multilayered approach, similar to the immune system,” he said.
Akridge tested the serum to ensure that its viscosity worked well with the sonic motion. “The product in the cup [must] have a gel viscosity, so [that] when we put it into the cup, it stays in place. The way the cup moves, it kneads the skin and it turns the gel to a liquid with the body heat and the sonic motion.” He added that this allows for improved spreadability and evenness of coverage of the serum around the eye area.
In addition, the serum had to be at the proper pH. “We did not want an acidic formulation moving at 125 touches a minute; therefore, we designed a formulation with pH 5.5,” said Akridge.
The company has extensively tested the device on women aged 18–65 and has found no adverse reactions. Plans for new formulations to use with the device are under way and may possibly include spot treatments, such as for hyperpigmentation and acne.
