Detailed explanation-2: -The holothurins are shown to have anti-melanogenic and anti-wrinkling effects on human skin by inhibiting melanin production in Melan-A cells and promoting collagen production in human dermal fibroblasts via the ERK pathway.

Detailed explanation-3: -Sea cucumbers produce a toxin known as holothurin, which is contained in specialized structures called Cuvierian tubules and secreted onto the outer surface of the body wall. Some species also eject portions of their toxic inner organs through the anus as a defensive mechanism.
