Whenever there is a defect in the skin or a non-vital section of skin, such as from burns or other damage resulting in scars, it needs to be replaced with a partial or full thickness skin grafting. Skin generally covers the entire body and protects underlying tissues from damage and infection. It also provides thermoregulation via skin temperature changes and radiation of heat through the skin. Restoring a normal skin border is the purpose behind skin grafting.

Skin grafting was performed two millennia ago in India but wasn’t popular in western medicine until almost two hundred years ago. Grafting was found to speed healing and reduce fluid loss from major wounds and burns. Grafting makes wounds look better and reduces scar contraction. Wounds that extend to bone must be grafted because bone does not cover itself with tissue or skin.

Hydrofluoric acid is one of the most dangerous Acid Injuries of acids to come in contact with. In an aqueous solution, it is a colorless and fuming liquid with a strong and irritating smell. It is highly corrosive and usually comes in concentrations of 46 percent and 53 percent. It can be diluted to much less concentrated solutions or concentrated to above 70 percent.

The most unique property of hydrofluoric acid or HF is that it attacks glass, etching it. It can dissolve stone and silica so it must be kept in wax, lead, or plastic bottles. It has an extremely caustic effect on any kind of organic tissue. The industrial uses of HF include frosting, etching and polishing glass, removing sand from castings made of metal and for etching silicon wafers in industrial processes, such as the manufacturing of semiconductors.
