Solution Overview
Problem
Current radiofrequency energy therapy for skincare lacks effectiveness in penetrating specific layers of the skin efficiently and safely, as it is limited by skin impedance and temperature, and often results in side effects due to inadequate conditioning of the skin.
Innovation Solution
A dermal device with a fluid circuit and dermal interface featuring electrodes and perforations, which delivers energy pulses and chilled topicals to condition the skin by reducing impedance and temperature, allowing for enhanced penetration and efficacy of RF energy therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If radiofrequency energy is applied to the skin, then therapeutic effects are achieved, but skin impedance limits penetration depth and efficacy
Solution Approach 1:
The device applies a chilled topical solution to the skin before delivering radiofrequency energy pulses. This preliminary cooling action reduces skin impedance, thereby improving the penetration depth and efficacy of the subsequent RF energy therapy.
2Productivity
If radiofrequency energy is applied to the skin, then therapeutic effects are achieved, but temperature increase causes side effects
Solution Approach 1:
The device applies cooling to the skin before and during radiofrequency energy delivery to counteract the heating effect. This preliminary anti-action prevents excessive temperature increase and associated side effects while maintaining therapeutic efficacy.
Solution Approach 2:
The device converts the harmful heating effect of RF energy into a beneficial therapeutic outcome by simultaneously applying cooling. The controlled temperature management allows RF energy to achieve therapeutic effects (neocollagenesis, neoelastogenesis) while preventing harmful overheating.
3Productivity
If radiofrequency energy is applied to the skin, then skincare benefits are achieved, but inadequate skin conditioning results in side effects
Solution Approach 1:
The device applies a chilled topical solution to condition the skin before RF energy delivery. This preliminary conditioning improves skin receptivity and reduces impedance, enabling safer and more effective RF therapy.
Solution Approach 2:
The chilled topical solution acts as an intermediary between the RF energy device and the skin. It mediates the interaction by conditioning the skin surface, reducing impedance, and protecting against excessive heating during RF energy delivery.
