Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Transepidermal Water Loss (TEWL)
Trans-epidermal water loss (TEWL) measurement (only for the first 10 participants 1-10) before and after application of STAR particles \[(T0 (before), T20 (after), T30 (after)\].
Before application, 20 minutes after application, and 30 minutes after application
Secondary Outcomes (3)
Sensation After Application of STAR Particles (Part 2 Only)
Immediately After STAR particles application
Evaluate Pain Using the Visual Analog Pain Scale (VAPS) After Application of the STAR Particles (Part 2 Only)
Immediately After STAR particles application
Number or Participants Who Reported Standard Adverse Event (AE)
Up to 5 days after the STAR particles removal (for a total of 5 days)
Other Outcomes (1)
Number of Participants Who Experience Adverse Events Due to Residual STAR Particles
After STAR particles removal up to 30 days (for a total of 30 days)
Study Arms (2)
STAR Particles application
EXPERIMENTALParticipants will receive the 8 interventions (different application pressures) plus the control (Site and treatment will not be randomly assigned on the arm) by the investigator.
Control Application
OTHERParticipants 1 to 10 will receive one control application on the volar side of one forearm. Participants 11 to 20 will receive one control application on the opposite forearm and on the contralateral side of the face.
Interventions
A 1.5-gram dose of STAR particles (10% concentration in aloe vera ointment) will be applied to the eight application sites (forearm and hand). Two rubbing cycles (30 and 60 cycles at a minimum of 1 cycle/second) and three pressures (40, 60, and 80 kPa) will be evaluated
A 100mg dose of the gel without STAR particles is applied to the control site (the forearm for all participants and, additionally, the face for participants 11-20).
Eligibility Criteria
You may qualify if:
- Adult, 18 - 39 years of age
- In good general health as determined by a medical history
- Willing and able to provide informed consent and follow all study requirements
- Not pregnant and does not desire to become pregnant in the subsequent two months
You may not qualify if:
- Has a known allergy or sensitivity to aloe vera or alumina
- Has any skin disorders or skin allergies
- Has any medical condition that may affect skin or skin sensation
- Has abnormal (e.g., tattooed) skin at forearms
- Has known neurological condition affecting sensory function or perception of pain
- Has inflammatory bowel disease
- Has applied skin ointment or cream to forearms in the previous 24 hours
- Has a major congenital or chromosomal abnormality known to affect the skin
- Has taken pain medication in the last 24 hours
- Is currently participating in another interventional clinical trial
- Has previously participated in a STAR particle interventional clinical trial
- Is pregnant or wishing to be pregnant
- Has any condition (social or medical), which in the opinion of the investigator would make study participation unsafe, would interfere with adherence to the clinical study requirements, or would complicate data interpretation
