Mosquito bites leave millions of Aussies scratching their skin, with this summer predicted to be particularly itchy in certain parts of the country. While most mosquito bites are little more than a minor inconvenience, some bites can lead to serious skin issues.
“Repeated scratching and skin trauma can break down the skin barrier, creating entry points for bacterial infection and leading to potential scarring and hyperpigmentation,” says celebrity skin expert, Isabella Loneragan.
What Happens When A Mosquito Bites?
“It pierces the skin using a highly specialised mouthpart called a Proboscis to suck up blood. Interestingly, only female mosquitoes bite humans because they need the proteins from our blood to produce their eggs. After a mosquito injects saliva into human skin, the body’s reaction typically results in a bump and itching for a day or two.”
Caring For Mosquito Bites
“Most won’t need to see a medical professional for a mosquito bite,” says Isabella. “However, if you develop a rash, fever, chills, headache, joint or muscle pain, fatigue or other flu-like symptoms, don’t risk it and do see your doctor.
“In addition to refraining from excessive scratching, it’s really important to keep a mosquito bite clean so you don’t develop a secondary inflection. Start by cleaning the area with soap and water to prevent infection, then apply a cold compress or ice pack for 10-15 minutes to reduce inflammation and relieve itching. While urban myths suggest everything from mayonnaise to mouthwash, sticking to a cold compress or a fragrance-free moisturiser is best.”
For extra soothing, look for products with natural anti-inflammatory ingredients like aloe vera, tea tree oil, or lavender oil, says Isabella.
“Non-scented hydrating lotions can support healing, reduce scarring, and tackle dryness that makes itching worse. If the bite is particularly inflamed, try a topical antihistamine, hydrocortisone cream, or even oral antihistamines for multiple bites. Over-the-counter pain-relieving creams with benzocaine or lidocaine can also work wonders. And remember – hydrated skin heals faster, so drink up! Most importantly (and yes, it’s hard), resist the urge to scratch. Your skin will thank you.”
Dealing With Mosquito Bites That Might Scar
Hopefully, it never gets this bad, but some are simply prone to angry reactions from mosquito bites. Isabella is here to help. “Firstly, always see your doctor if the post-bite symptoms are excessive,” she stresses Isabella. “Next, the best way to prevent scars is to refrain from scratching. Although, I concede that this can be tough, especially for kids and even for the most self-disciplined adults.”
With this in mind, if it looks like it might scar, follow Isabella’s sage advice:
Keep The Bite and Surrounding Area Moisturised
A gentle and fragragrance-free moisturiser, or even petroleum jelly, can help to reduce scar formation. Aloe vera is also great for helping to heal mild scars. Drinking plenty of water and consuming foods rich in vitamins and minerals – especially C, E and zinc – also supports skin repair.
Apply Serums
Look for serums with vitamin E or C, Niacinamide and antioxidants that promote collagen production and healing. Regular application of these should help to reduce the scar’s appearance over time. Ragan Skin Pigment Power is excellent for this puirpose – a self-promoting plug here but Pigment Power’s hero ingredients are great for helping to heal the skin.

These can help to soften and lighten scars
Light Exfoliation
This will help to remove dead skin cells and promote skin renewal, but be gentle! Don’t overdo it because harsh exfoliation may worsen the irration.
Massage The Scar
Do this gently and daily. It can help to improve blood flow and break down scar tissue.
Sun Protection
This is crucial on the bite area too, as UV rays can darken scars and make them more noticeable.
For more serious scars, in-clinic treatments that may be appropriate include: chemical peels and laser resurfacing; LED light therapy (especially red light therapy for reducing scarring); a HydraFacial treatment is gentle and good for fresh scars; and microneedling and microdermabrasion treatments can also help to reduce or remove scarring.
Evading Mozzies In The First Place
Aside from staying inside, you’d think it would be as easy as spraying some Aerogard. Sadly, no. Protecting your precious skin is a little more involved, but not much.
“Start with an approved insect repellent containing DEET, picaridin, or oil of lemon eucalyptus — these are proven effective and registered safe in Australia,” says Isabella. “Always use body repellents, not bug sprays with insecticides, as the latter can harm humans. Body repellents don’t kill bugs; they simply deter them,” advises skin expert Isabella Loneragan.
“For best results, patch test first, avoid broken skin, and steer clear of the eyes and mouth. Layer sunscreen first, letting it dry before applying repellent to maintain its effectiveness. Ensure full coverage by rubbing on a thin, even layer — don’t just mist and hope!”
Isabella also stresses that wearing light, loose clothing, especially at dawn and dusk when mozzies are most active, helps. “Also, opt for covered footwear and socks to protect ankles and lower legs, a mozzie hotspot. Reapply repellent after swimming or sweating, as mosquitoes are drawn to body heat, sweat, and skin scents.
“Skip mosquito wristbands and patches, as they’re ineffective, and stick to children-specific formulations for kids under three—never let them apply it themselves. Finally, avoid swamps and wetlands in summer, where mozzies are most dangerous and may carry serious infections.”
