Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm, using a mechanical apparatus, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes formed can be well-tolerated by the skin, and can exhibit shorter healing times and less swelling than conventional resurfacing procedures. The apparatus includes one or more needles adapted to remove a small portion of tissue when inserted into and withdrawn from the skin. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The exemplary method and apparatus can produce cosmetic effects such as increases in collagen content, epidermal thickness, and dermal / epidermal junction undulations in the skin.

A system and method for performing fractional resurfacing of a target area of skin using electromagnetic radiation are provided. An electromagnetic radiation is generated by an electromagnetic radiation source. The electromagnetic radiation is caused to be applied to a particular portion of a target area of skin. The electromagnetic radiation can be impeded from affecting another portion of the target area of the skin by a mask. Alternatively, the electromagnetic radiation may be applied to portions of the target area of the skin, other than the particular portion.

A skin resurfacing device for peeling the outermost layer of the skin for renewing the skin surface and repairing skin damage including a housing, a skin sensor, and a skin treater. The skin treater consists of an abrasive tip, a first end, a transparent portion, a first filter, and a second end, all of which are detachable and replaceable. The skin treater is connected to a vacuum source by a tubular hose. The vacuum provides both closeness of contact between the abrasive tip and the user's skin and the suctioning of skin debris peeled off. The skin treater, especially the abrasive tip are made with common material and mass production process so that they are disposable and economic.

Dermabrasive compositions for skin resurfacing are disclosed. Therapeutic compositions disclosed are derived from Porifera species, specifically sponges, and more specifically fresh water sponges. One disclosed embodiment is derived from Spongilla species and is formulated with pharmaceutically acceptable excipients.

A dermatological laser apparatus for irradiating human tissue with optical pulses includes a laser source (2) producing an optical output, a pulse shaper (4) coupled to the laser source for converting the optical output into optical pulses having desired shapes, and an optical delivery tool (8) coupled to the pulse shaper for applying the optical pulses sequentially to a multiplicity of sites on the human tissue with consecutively irradiated sites being non-adjacent.

Non-ablative skin resurfacing can include generating electromagnetic radiation having a wavelength of about 1920 nm to about 1950 nm and a fluence of about 3 J / cm2 to about 6 J / cm2. The electromagnetic radiation is delivered to a target region of skin to cause thermal injury to the epidermis in the target region sufficient to elicit a healing response that produces a substantially improved skin condition without detachment of the epidermis (e.g., within 3 days of treatment).

The invention relates to a mechanical skin resurfacing device and a method for use. The method for resurfacing the skin includes imparting sufficient energy to a motorized device to cause a mass of less than 4 grams to move in an eccentric orbit, thereby urging an abrasive coupled to the said device to vibrate; and contacting said skin with said vibrating abrasive.

The present disclosure relates to a method, device, and storage medium for face image skin smoothing, the method comprising: acquiring pixel values ​​of pixels of the image; performing smoothing processing on the image based on the pixel values; Masking the image with pixel values ​​to distinguish the skin-colored part and the non-skinned part of the image; fusing the non-skinned part of the image with the skin-colored part of the smoothed image to obtain a fused image ; Perform sharpening processing on the skin color part of the fused image to increase the texture of the skin color part of the fused image. It is used to solve the technical problem of loss of texture details after some skinning algorithms in the related art process face pictures, as well as the technical problems of manual skinning that cannot be automated and highly complex.

The invention discloses a high-naturalness real-time beautifying method and device, and the method comprises the steps: employing a single-channel high-contrast image buffing method which employs the channel with the smallest number of interference noise points in three channels r, g and b, and effectively reduces the noise interference from other channels while reducing the calculation amount; obtaining the roughness information of skin through calculating a single-channel high-contrast image buffing image, thereby avoiding the skin distortion caused by the direct filtering of the image, and improving the naturalness of skin; and employing a layer mixing and overlapping method: employing a method of filtering, light softening and brightening mixing and overlapping to achieve an effect of skin buffing and whitening and to maintain the naturalness of the image after a buffing layer is calculated and obtained. The device is used at a mobile intelligent terminal, enables human face to remain natural while beautifying, whitening and buffing the face skin, greatly reduces the buffing track, and enables the reduction degree of edges and shadows of a human face to be high.

It has been discovered that vascular endothelial growth factor (“VEGF”) promotes migration of activated (but not differentiating) keratinocytes to skin. This growth factor specifically increases migration of keratinocytes of the “wounded skin” phenotype but does not have significant effects upon differentiated keratinocytes. It also increases collagen deposition and reduces wrinkles, enhances skin quality, and increases skin thickness to normal levels in individuals where skin has thinned due to age or disorder such as diabetes. It is particularly well suited for use as cosmeceuticals when applied in purified form and in known amounts. The data presented in the examples demonstrate efficacy and specificity of VEGF in enhancing migration of normal human keratinocytes as well as formation of new granulation tissue including collagen formation. VEGF induces keratinocyte and fibroblast migration, formation of new tissue, and not only induces deposition of collagen but improves alignment of the collagen fibers. Accordingly, this growth factor is highly suitable for use as a cosmeceutical, especially for skin resurfacing and reduction in wrinkles.

The embodiment of the invention discloses a video image processing method and device. The method comprises the steps of obtaining a video image, wherein the video image is the image belonging to a brightness chrominance YUV video stream; determining a blue chrominance component U and a red chrominance component V in the video image, and determining a skin color of a face in the video image according to the U and the V; carrying out skin grinding on the video image according to a brightness component Y of the video image and the skin color, carrying out hue adjustment on the skin grinded image by employing the skin color, and outputting the hue adjusted image. On the basis that the video image is featured by continuity, image optimization is carried out on the face in the video image, the background quality of the video image can be adjusted, and the quality of the video image is improved.
