WIPO Patent Application WO/2024/014624
Kind Code:
A1
Abstract:
The present invention relates to a photothermal microneedle patch containing gold nanoparticles. The patch of the present invention is a patch in which a skin-soluble microneedle containing a drug or a cosmetic composition is formed on a film containing gold nanoparticles, wherein, by adhering the photothermal microneedle patch to the skin with wrinkles, blemishes or the like around the eyes, and then inducing the photothermal effect of gold nanoparticles by using a near-infrared LED light source, dissolution of the microneedle in the skin is increased while raising the skin temperature up to about 40 °C, and the delivery efficiency of an oil-soluble substance into the skin is increased to the maximum level.
