A1. BOHLD Consulting is the only U.S. dermatology consultancy dedicated exclusively to the skin–device interface. We provide expertise on how consumer wearables (such as smartwatches, fitness trackers, AR/VR goggles, earbuds, and fitness rings) and medical devices (including CGMs, microneedle patches, ECG/EMG sensors, and hearing aids) interact with skin.

A5. BOHLD Consulting is the only U.S. dermatology consultancy dedicated exclusively to the skin–device interface. Led by a board-certified dermatologist with additional certification in laser medicine, we bring together clinical dermatology, regulatory insight, and device engineering awareness. Our expertise is strengthened by extensive immunology training and years of clinical patch testing experience, giving us a deep understanding of how skin responds to adhesives, metals, polymers, and coatings. This rare combination allows us to anticipate risks, design effective testing strategies, and translate medical findings into practical guidance for product teams. Our focus on wearability, safety, and compliance ensures that both consumer wearables and medical devices can be designed and deployed with confidence.
