Aldena STAR Particles

The objective of this study is to find out the best method of applying STAR particles to the skin. STAR particles are very small particles with microneedles on the surface that can increase and create small punctures in the skin. The small punctures should allow for different topical medications to work more effectively. This is important to understand the potential use of STAR particles in future topical medications. This study will not use any medication with active ingredients. The study will include healthy adult participants. The first visit will be to collect medical information and assess eligibility in the study. The second visit will have the application of STAR particles on different areas of the arm, hand, and face with different pressures to determine what the most effective method of application is. The skin will be evaluated after the application, and surveys will be collected on the tolerability of the application.
