Detailed answer

When someone with allergies experiences an allergic reaction, their body releases histamines, which can cause inflammation. Inflammation can slow down the healing process by impairing blood flow to the affected area and interfering with the formation of new tissue. Allergic reactions can also lead to itching and scratching, which can disrupt the healing process and potentially worsen the appearance of scars. Additionally, allergies can trigger eczema or dermatitis, which can further hinder scar healing. It is important for individuals with allergies to manage their allergic reactions effectively and consult with healthcare professionals for appropriate treatment to minimize any potential delays in scar healing time.
