How can I prevent or minimise scarring after an insect bite?

Doctor's Answers (2)

I agree with Dr Theng's answer to your question. Do not pick your insect bites no matter how itchy t especially if its on your face and you want to prevent scarring. Topical antibiotics (e.g. Fusidic Acid) help to prevent an infection, that might aggravate the bite and worsen scarring. Topical steroids (e.g. Hydrocortisone) will help reduce inflammation if there is an exaggerated immune response causing causes excessive inflammation.

To add on, keeping the area well hydrated with moisturisers during the recovery period will help reduce scarring. Remember to avoid sun exposure and to apply sunblock regularly to prevent darkening of the scar. Good nutrition and a diet full of vitamins and omega oils can improve scar healing as well.

Lastly, if the indentation does not resolve, you may consider injecting a collagen stimulator, PDRN (e.g. Rejuran Healer) into the scar, or using dermal fillers to fill up the indentation on your forehead.

Hope that helps!

In general, after an insect bite, it is important to minimize picking and scratching at the rash as this can aggravate the swelling and increase the risk of scarring. 

It is also important to prevent infection and keep the area clean. Topical antibiotics may be helpful especially of there is a wound and overlying redness. 

Some people may develop an exaggerated insect bite reaction and the area of the bite can become very inflamed. Topical steroids can help reduce the inflammation.

For the current scar, this should usually get better with time. Silicone based scar gels may help in the healing. You can consider seeing your doctor for a proper assessment of the scar to advice you further on the treatment options.
