Is it normal to feel itchy or see pressure marks after wearing a knee brace?

Because our products provide medical-grade compression, mild pressure marks on the skin after removal are normal and usually disappear within a few minutes.

Regarding itching:
This is more common after exercise when sweat accumulates between the skin and silicone strips, which may cause irritation.

Recommendations:
Remove the knee brace promptly after exercise, clean your skin, and allow the brace to air dry.

Warning:
If you experience persistent redness, rash, or a severe allergic reaction, discontinue use immediately and consult a physician.


How long does a knee brace last? When should I replace it?

Knee braces are consumable protective products. Elastic fibers gradually lose strength over time, depending on usage frequency (e.g., daily running vs. occasional walking).

General guideline:
With proper care, a knee brace typically lasts 6 months to 1 year.
If the brace starts slipping or no longer provides adequate support, it’s time to replace it.


How should I wash my knee brace? Can it be machine-washed?

To protect the elasticity and internal components, hand washing is recommended.
Wash with cold or lukewarm water and air dry naturally.
Do not bleach, iron, or dry clean.

Braces can be used alongside other pain relief medications to manage overall knee pain effectively.
