FAQ & Usage Guidelines

For your safety, ERfit ear patches are not recommended for the following individuals:

Pregnant or breastfeeding women
Individuals with broken skin, inflammation, eczema, or infection on or around the ears
Individuals with serious heart conditions, severe hypertension, or other major chronic illnesses
Individuals with known allergies to adhesives or metal materials
Children under 12 years of age (use only under adult supervision)

If you experience redness, itching, stinging, irritation, or any allergic reaction after application, please remove the ear patch immediately and discontinue use.

ERfit is a daily wearable accessory and does not provide medical, therapeutic, or healthcare benefits. If you feel unwell, please consult a medical professional promptly.

ERfit ear patches are made with medical-grade, low-allergen adhesive materials designed to minimize skin irritation.

However, skin sensitivity varies from person to person, and individual reactions may differ.

ERfit ear patches typically last 2–5 days, depending on individual usage habits and environmental conditions.

The following factors may reduce adhesion time:

Oily skin or use of skincare products
Sweating, showering, or humid environments
Frequent touching or friction
Improper storage after opening
Prolonged exposure to heat or moisture

For best results, store unused ear patches in a cool, dry place and reseal the packaging whenever possible after opening.

ERfit ear patches are suitable for normal daily wear. However, heavy sweating, frequent water exposure, or side-sleeping with friction may affect adhesion and wear duration.

It is recommended to remove the ear patches before intense exercise, swimming, or prolonged bathing.

ERfit ear patches are single-use only
Reapplication after removal is not recommended

Clean and thoroughly dry the area of the ear before application
Gently peel off the ear patch
Apply to the designated ear area and press lightly to secure

For hygiene reasons, each ear patch is intended for one-time, personal use only.
