Our sheets combine strong yet gentle medical adhesive with breathable backing material to provide reliable wound care waterproof protection for daily life.

A: The sheet forms a waterproof, micro-occlusive barrier over the treated area. This barrier prevents water and contaminants from entering while allowing moisture vapor to escape, which supports a clean healing environment.

A: Yes — our tattoo protective sheet / tattoo waterproof sheet is designed to protect fresh tattoos from water, friction and contamination during the initial healing phase. Always follow your tattoo artist’s or clinician’s aftercare guidance; do not apply on actively bleeding or heavily exuding wounds unless advised by a professional.

Clean and gently dry the skin around the wound or tattoo.

Cut the sheet to size if needed.

Apply the adhesive side smoothly over the site, pressing edges to seal.

To remove, slowly lift an edge and peel back gently; use an adhesive remover if needed to reduce skin irritation.
