Itching at the scar site may result from hypertrophic scarring, excessive keratinocyte proliferation (leading to raised scars on the skin surface), or inflammation/infection at the wound site. Disinfection with hydrogen peroxide or iodophor is recommended. In daily life, it is essential to maintain a balanced diet and avoid spicy or irritating foods.
