A physician performing laser resurfacing using an erbium laser Laser resurfacing is a laser surgery technique that disassociates molecular bonds . It is used for the treatment of wrinkles, solar lentigenes , sun damage , scarring ( acne scars and surgical scars), stretch marks , actinic keratosis , and telangiectasias .
Tattoo ink (or similar agent) is rubbed into a fresh cut to add color or extra visibility to the scar. Most of the ink remains in the skin as the cut heals. This was how tattoos were initially done before the use of needles to inject ink. [17] Skin removal/skinning Skin removal allows for larger markings than simple cutting.
The Texas brown snake (Storeria dekayi texana), a subspecies of Storeria dekayi, is a nonvenomous snake in the family Colubridae. It is endemic to North America . [ 1 ]
Other venoms instigate localized tissue damage around the bitten area, and immobilization may increase the severity of the damage in this area, but also reduce the total area affected; whether this trade-off is desirable remains a point of controversy. Because snakes vary from one country to another, first aid methods also vary. [citation needed]
Due to small fangs, bites happen when trapped against one's skin by clothing, bed sheets, etc. Most encounters with this spider occur from moving boxes or rooting about in closets or under beds. The range of the brown recluse, L. reclusa in the U.S. is limited to the central and southern states. A number of related recluse spiders (some non ...
Scar free healing is the process by which significant injuries can heal without permanent damage to the tissue the injury has affected. In most healing, scars form due to the fibrosis and wound contraction, however in scar free healing, tissue is completely regenerated. During the 1990s, published research on the subject increased; it is a ...
The time duration (pulse duration) of the laser energy must be very short, so that the tattoo pigment is heated to fragmentation temperature before its heat can dissipate to the surrounding skin. Otherwise, heating of the surrounding tissue can cause burns or scars. For laser tattoo removal, this duration should be on the order of nanoseconds.
Laser-assisted drug delivery (LADD) is a drug delivery technique commonly used in the dermatology field that involves lasers. As skin acts as a protective barrier to the environment, the absorption of topical products through the epidermis is limited; thus, different drug delivery modalities have been employed to improve the efficacy of these treatments.
