itsekalvo
itsekalvo is a Finnish term that translates to "self-tanning" in English. It refers to the application of cosmetic products designed to temporarily darken the skin, giving the appearance of a suntan without exposure to ultraviolet (UV) radiation. These products typically contain dihydroxyacetone (DHA) as the active ingredient, which reacts with the amino acids in the outermost layer of the skin (stratum corneum) to produce melanoidins, compounds that mimic the color of a natural tan.
The process of using itsekalvo products involves applying lotions, mousses, sprays, or wipes evenly to the skin.
