Microneedling for Dermal Rejuvenation

A skin treatment device using micro-needling for cosmetic treatments like collagen stimulation without requiring specialized training or restrictions on intensity. The device has a handpiece with a recessed needle element that can be inserted into the skin. A pulsating vacuum is generated to draw the skin into the handpiece for treatment. The vacuum alternates between strong and light levels to prevent contamination. The recessed needle design prevents the skin from being pressed instead of pierced, especially on loose or bumpy areas.

A cosmetic method using small needles to resist skin aging without the need for repeated filler injections. The method involves injecting a nutrient-rich solution into specific aging areas using small needles. The needles create tiny wounds that stimulate collagen and elastin production to restore firmness. The nutrients also provide moisture to plump the skin. The repeated micro-injuries trigger self-repair and collagen production.

A skin treatment needle with uniform energy distribution to minimize damage to the epidermis and supply energy to various depths within the skin for faster healing. The needle has a conductive portion with wrinkles on its outer surface to form a differentiated electric field compared to the rest of the needle. This focused field avoids excessive concentration of energy in the epidermis. The wrinkles distribute the electric field more uniformly as the needle penetrates the skin. The wrinkled conductive portion is etched into the needle body by micromachining. An insulating coating covers the non-conductive parts of the needle. This allows targeted energy delivery at different depths without damaging the epidermis.

Reducing skin surface area, like wrinkles, by forming a plurality of small holes in the skin and then applying tensile or compressive stresses during healing. The small holes, measuring around 0.2-0.7mm, are formed using coronoid biopsy needles. Applying stresses in a specific direction enhances the overall reduction of the treated area and provides a directed displacement of the contraction. The stresses are maintained until the holes close to prevent scarring. This method allows directed skin tightening without large scars compared to traditional surgery.
