Question 1

What does BOHLD Consulting specialize in?

Accepted Answer

BOHLD Consulting is the U.S. dermatology consultancy focused exclusively on the skin–device interface, from consumer wearables to medical devices. We help companies prevent and solve skin irritation issues linked to materials, design, adhesives, and use conditions.

Question 2

Why does skin irritation matter in wearable technology?

Accepted Answer

Skin irritation is a leading cause of device abandonment and complaints. Addressing dermatologic risks early improves safety, comfort, regulatory readiness, and long-term wearability and adoption.

Question 3

How does BOHLD Consulting help medical device companies?

Accepted Answer

We provide independent medical assessments to determine root causes of irritation; design standardized questionnaires with algorithmic analysis for efficient triage; assist with clinical trial design and interpretation for skin-based devices; evaluate irritation and compatibility data; and deliver dermatology and regulatory input to support FDA and ISO compliance—drawing on immunology training and years of clinical patch testing experience.

Question 4

Can BOHLD Consulting help with consumer electronics like smartwatches or earbuds?

Accepted Answer

Yes. We support smartwatches, fitness trackers, AR/VR goggles, earbuds, and fitness rings. We assess adhesives, materials, sweat/heat management, and pressure points to reduce rashes and pressure injuries, and we provide design recommendations that improve wearability and user comfort.

Question 5

What makes BOHLD Consulting unique?

Accepted Answer

We are the only U.S. dermatology consultancy dedicated to the skin–device interface, led by a board-certified dermatologist with laser medicine certification. Our work combines clinical dermatology, immunology and patch testing expertise, regulatory insight, and practical awareness of device engineering to deliver solutions that balance safety, compliance, and wearability.

Question 6

Does BOHLD Consulting work with startups as well as established companies?

Accepted Answer

Yes. We help startups anticipate skin compatibility challenges in early prototypes and support established companies with dermatology assessments, regulatory guidance, and clinical trial support—scaling services to improve safety, compliance, and wearability at any stage.

Question 7

How can BOHLD Consulting improve wearable product design?

Accepted Answer

We focus on the skin–device interface to reduce friction, heat retention, and moisture buildup through dermatology-informed input on materials, adhesives, and band or housing design. We develop skin preparation protocols for sensors that need specific skin conditions and provide best-practice handouts to mitigate human-factors risks (e.g., external irritants or care habits). Backed by years of clinical dermatology and extensive wearables consulting, we help teams achieve innovative design and proven compliance—without sacrificing wearability.

We are based in California and serve clients across the United States and internationally, offering on-site, remote, and hybrid engagements.
