Top 10 facts about the world. Skin exfoliation, or the process of removing dead skin cells from the body and face, can be accomplished in a variety of ways. Gommage is one method of exfoliation. Considered highly effective, a gommage exfoliant can leave skin clean and soft. A paste or cream, gommage is administered onto the skin in a very thin layer. It is left on the skin to dry, but only slightly. It is then massaged and rolled off the skin. As the layers of dried paste fall off the body, so too do the skin's outermost dead cells.
Pressurized Aircraft (Part Three) Decompression. Explosive decompressionâa change in cabin pressure faster than the lungs can decompress, possibly causing lung damage. Normally, the time required to release air from the lungs without restrictions, such as masks, is 0.2 seconds. Most authorities consider any decompression that occurs in less than 0.5 seconds to be explosive and potentially dangerous.
Decompression sickness (DCS, also called the bends or caisson disease) is the result of inadequate decompression following exposure to increased pressure. In some cases, the disease is mild and not an immediate threat.he reason is that the risk factors, both known and unknown, can influence the probability of DCI in myriad ways. Because of this, evaluation of a diver for possible decompression illness must be made on a case-by-case basis by evaluating the diver&#39s signs and symptoms and not just based on the dive profile.
