Currently, two major perforating diseases include reactive perforating collagenosis and elastosis perforans serpiginosa. In some literature, acquired perforating dermatosis is a third major group and is a catch-all term for cases of perforating disease arising in adults, usually associated with a systemic disease. Kyrle disease is characterised by the formation of large papules with central keratin plugs and is often associated with hepatic, renal or diabetic disorders.
Other glow products contain a small glass vial inside the plastic tube that contains a mixture of hydrogen peroxide in phthalic ester (a substance that is added to plastics to increase flexibility, durability and transparency). Outside of the glass vial is another chemical called phenyl oxalate ester.
Glow sticks work by chemiluminescence â that is, the light is emitted as a product of a chemical reaction. Items that need to glow continuously with little or no âcharge,â like clock or watch hands that glow for hours after a light has been turned off, work by radioluminescence.
