Wrinkles Schminkles Self-Dissolving Microneedle Patches use an innovative technology to directly deliver active ingredients deep into the skin that are often difficult to absorb. With 1800 Microneedles the patches work by self-dissolving and releasing the active ingredients into the dermal layers of the skin to smooth fine lines and wrinkles. Designed to fit under your eyes, around your mouth or middle of forehead, our microneedles are formed from crystalised hyaluronic acid, caffeine, collagen and peptides.
