Ultrasonic Methods for Dermal Matrix Restructuring

Skin treatment device using focused ultrasound and RF energy to shorten treatment time and increase recovery effect. The device uses RF energy to heat the treatment area to a temperature that increases ultrasound transmission efficiency. Then focused ultrasound is applied to coagulate the tissue. This two-step process improves ultrasound penetration and cell activity while avoiding excessive damage.

Less invasive method for reducing wrinkles on the skin surface using a combination of a medium containing cosmetic actives and ultrasound waves with lower energy than high intensity focused ultrasound (HIFU). The method involves applying the medium to the skin and then delivering focused or unfocused ultrasound waves through it. The ultrasound waves propagate into the skin to depths of 3 mm and produce localized temperature increases of 40-65°C for short periods. The lower energy ultrasound is more tolerable on the skin compared to HIFU. The actives in the medium improve wrinkles when combined with the ultrasound.

Ultrasonic skin treatment device that selectively provides fat reduction, fat increase, or elasticity enhancement based on applied ultrasound energy levels and patterns. The device uses a specialized control unit that enables targeted fat reduction, fat increase, or elasticity enhancement by applying specific ultrasonic energy levels to the skin layers. The device can use dot or linear ultrasound delivery methods to focus energy at varying depths and move horizontally. It applies energies like 0.1-0.3J to increase fat, 0.2-0.6J to reduce fat, and 0.2-0.6J to boost elasticity. By tailoring ultrasound dosage and patterns, the device aims to avoid tissue damage and promote selective fat, elasticity, or both changes.

Ultrasound device for selective treatment of subcutaneous tissue like adipose and connective tissue to rejuvenate and reshape the body without cell death or burns. The device has a multifocal ultrasound transducer that emits a low intensity, low frequency sound field with varying amplitude and work cycle. This focuses energy over a wider area than conventional ultrasound, reducing metabolic load and permeability to induce physiological lipolysis and tissue remodeling without saturation. The multifocal beam avoids cell death and cavitation effects. The device excites at frequencies selective to fat diameters and uses long off-times between bursts to expel heat.

Reducing wrinkles on the skin using a non-invasive method that combines a medium containing cosmetic actives with ultrasonic waves. The method involves applying a medium with active ingredients like hyaluronic acid to the skin, then applying focused pulsed ultrasonic waves to propagate through the skin. This method aims to improve wrinkles without invasive needles or injections. The ultrasonic waves can be customized to generate local temperature rises in the skin. The medium with active ingredients enhances the effects of the ultrasound on the skin.

Reducing wrinkles on the skin using a combination of a cosmetic medium and low-energy ultrasound waves. The method involves applying a medium containing cosmetic actives like hyaluronic acid, peptides, and ceramides to the skin. Ultrasound waves with frequencies between 10 kHz and 50 MHz are then applied to the skin through the medium. The ultrasound waves propagate into the skin to depths up to 3 mm, generating localized temperature rises. This less-invasive approach improves wrinkles by combining cosmetic benefits from the medium with targeted skin heating from the ultrasound.
