Description

Shockwave Stimulation Device for Skin Beauty The present invention relates to a non-invasive skin stimulation device using shock waves, and a shock wave stimulation device for skin beauty that uses a single piezoelectric element to deliver shock waves to the skin layer. Modern skin aesthetic technology primarily aims to promote collagen production, reduce wrinkles, provide lifting effects, and remove pigmentation. Non-invasive procedures are gaining popularity to improve skin condition, with representative technologies including ultrasound (HIFU), laser, and radio frequency (RF) stimulation. High-Intensity Focused Ultrasound (HIFU) utilizes high-intensity ultrasound to concentrate heat on specific tissues, serving in cosmetic applications such as skin lifting, wrinkle reduction, and fat coagulation, as well as in oncology. It provides long-term skin improvement by non-invasively stimulating collagen production, and in some procedures, immediate lifting effects are observed. Furthermore, high-intensity ultrasound enables precise focusing, allowing for the minimization of damage to surrounding tissues during tumor removal. However, since HIFU primarily uses thermal energy, its effectiveness in treating musculoskeletal pain or inflammation is limited. Additionally, the high cost of the equipment and procedure is a limitation, and precise operation by skilled medical professionals is required. Furthermore, HIFU carries a risk of skin overheating or burns due to the high-temperature stimulation caused by ultrasound, and swelling and pain may occur after the procedure. Laser devices use light energy of specific wavelengths to induce the removal of pigmentation on the skin surface, improvement of blemishes, and reduction of wrinkles. However, while lasers promote skin regeneration, redness or a recovery period may be required after the procedure. Additionally, because lasers primarily act on the epidermal layer, they are effective for blemishes, freckles, and pigmentation issues on the skin surface, but they have limitations in stimulating deeper layers such as the dermis or the SMAS layer. Radio frequency (RF) devices generate heat in the skin and subcutaneous tissue using electromagnetic waves in the range of 3 kHz to 300 GHz. RF energy delivered to the skin surface primarily penetrates the dermis and subcutaneous fat layers, inducing friction between cells and converting into thermal energy. The heat generated at this time induces the production of collagen and elastin. However, high-frequency devices may cause discomfort during treatment due to heat and stinging, and repeated treatments are necessary because their effectiveness is limited. Additionally, since high-frequency waves primarily act on deep layers, there are limitations in their effectiveness in improving blemishes or pigmentation issues in the epidermal layer. Meanwhile, Extracorporeal Shock Wave Therapy (ESWT) is effective for non-invasively relieving pain and promoting tissue regeneration. It is primarily used for musculoskeletal conditions such as muscle pain, tendinitis, and plantar fasciitis, and has the advantage of increasing blood flow to reduce inflammation and accelerate recovery. Furthermore, its quick treatment time and simple procedure allow patients to return to their daily lives immediately, making it convenient. As such, ESWT has established itself as a powerful therapeutic tool for pain management and tissue healing. However, ESWT has limitations in improving surface tissues and is ineffective for cosmetic treatments such as improving skin elasticity or cell coagulation. Additionally, strong shockwaves can cause temporary pain or side effects in some patients, and often lack immediate effects, with results appearing over time. Therefore, there is a need for a shockwave device with an improved structure for precise treatment aimed at improving surface tissues.
