Skin comfort and irritation
A wearable sits against the skin for long periods, so fit, moisture and cleaning matter. ARC is not intended to evaluate or diagnose a skin condition.

Avoid excessive tightness
ARC should remain secure without painful pressure. Loosen the strap if the area feels numb, sore or overly compressed.
Give the skin a break
If you notice persistent redness or discomfort, remove ARC and allow the area to recover before wearing it again.
Do not wear over broken skin
Avoid placing the sensor over cuts, abrasions or actively irritated skin.
Persistent or severe reactions
Stop wearing the device and seek appropriate medical advice if irritation is severe, worsening or does not resolve.
