Insect bites come from an array of pests, such as bedbugs, mosquitoes, fleas and knats. The itching caused by insect bites can lead to excessive scratching, which in turn can cause infection and scarring. These scars can form into larger raised bumps called hypertrophic scars. Eliminating them improves the skin's appearance and can help heal underlying tissue.
Apply a thin layer of onion extract to the scars. Onion extract is a natural anti-inflammatory that inhibits the overproduction of collagen responsible for scarring, according to Columbia University. It comes in gel form and is also an ingredient in some over-the-counter scar treatments. Applying a thin layer of this gel two or three times daily will help reduce inflammation and speed the healing process.
Cover scars with a silicone sheet or a thin layer of silicone gel, available at most pharmacies. Silicone fades and flattens scars, although the exact mechanism by which it does so is unknown.
Apply an alpha hydroxy moisturizer to your scars daily. Alpha hydroxy acids are fruit extracts that act as natural exfoliants. They remove dead skin cells, resulting in smoother skin and faded scars.
Opt for noninvasive laser scar removal by a dermatologist. In this procedure, the doctor uses a low-intensity laser to resurface the skin by slowly removing the top layers of dead skin cells and exposing fresher skin underneath.
