Henna body art is made by applying henna paste to the skin: the lawsone in the paste migrates into the outermost layer of the skin and makes a red-brown stain.
Henna will not stain skin until the lawsone molecules are made available (released) from the henna leaf. Fresh henna leaves will stain the skin if they are smashed with a mildly acidic liquid. This will stain skin within moments, but it is difficult to form intricate patterns from coarse crushed leaves. Dried ground, sifted henna leaves are easily worked into a paste that can be used to make intricate body art. Commercially available henna powder is made by drying the henna leaves and milling them to powder, then the powder is sifted. This powder is mixed with lemon juice, strong tea, or other mildly acidic liquids. Essential oils with high levels of "terps", monoterpene alcohols such as tea tree, eucalyptus, cajeput, or lavender will improve skin stain characteristics. The henna mix must rest for 6 to 12 hours so the leaf cellulose is dissolved, making the lawsone available to stain the skin. This is mixed to a toothpaste consistency and applied with a one of many traditional tools, including resist techniques, shading techniques, and thicker paste techniques, or the modern cellowrap cone.
A properly applied design is a creation of great beauty and intricacy. The delicate lines and swirls have long been a fascination upon the female's skin. Thanks to more and more celebrities embracing Eastern culture, the influence has reached far into Western ideas and images of exotic beauty and continues to enjoy a rise in popularity.
