Abstract
An array of microneedles is provided to apply semi-permanent or permanent markings to skin, or to apply semi-permanent subcutaneous makeup or other cosmetic compounds to skin. The microneedles can apply identifications or other tattoo-like graphics, and will not enter into the dermal layer of the skin so that the application procedure is painless. The microneedle array is also useful for delivering specific compounds or actives into the skin, such as cosmetic compounds or nutrients, or various skin structure modifiers that can be delivered subcutaneously without having to visit a cosmetic surgery clinic.
