It has been a long drawn fantasy of the West to flaunt a tanned look on their bodies. Genetically speaking, skin tone of the Westerners has always been on the lighter side, yet the charm associated with the dark skin tone had increased their sun bathing and sun tanning processes. However, with the turn of the century, melatonin to induce a tanned look within the body has gained prominence.

Rather than specific tanning, in this mode, uniform tanning is obtained; that too for a longer time period. The peptides are directly introduced into the blood from where they react with melatonin receptors, stimulating production of melanin to enhance skin pigmentation.
