This study aims to find the best way to use **STAR particles** on the skin. STAR particles are tiny particles with small needles that create tiny holes in the skin. These holes help medications applied to the skin work better. The study involves healthy adults aged 18-39. There are two visits: the first is for medical checks, and the second is to try out STAR particles on the arm and hand. The researchers will use different pressures to see which works best and will check how the skin reacts.
The study does not involve any active medication, so it's just about testing the STAR particles. It lasts for a short time and only requires two visits. You should not have any skin allergies or be pregnant. Participants will not receive any compensation, but they will help advance new skin treatment methods.
- Two visits are required: one for medical checks and one for applying STAR particles.
- Participants must be healthy adults aged 18-39 and not pregnant.
- No active medication is used, focusing only on the STAR particles.
