Bug Bites, Rashes & Skin Allergies: Summer Skin Concerns 101

Summer is finally here, and so are the mosquitoes, mystery rashes, and sun-related skin reactions. As a dermatologist, I see a lot of these “summer skin emergencies” from people spending more time outside at barbeques, sporting events, and gardening sessions. I will never forget the patient who experienced severe poison ivy on the arms and legs after cleaning weeds out of their backyard. They were miserable and needed oral treatment quickly!

Let’s break down a few common culprits and what to do if they show up on you or your little ones:

Mosquito Bites & Bug Stings

Itchy? Red? Swollen? Bug bites can be more than just annoying. Scratching and rubbing can lead to infection and scarring.

Tips:

• Apply ice for 15 minutes a few times a day and fragrance-free hydrocortisone cream twice a day to decrease inflammation

• Take an oral antihistamine if swelling or itching is severe

• Keep nails trimmed to avoid breaking the skin when scratching

• Contact me for stronger topical treatment if it does not improve

Poison Ivy, Oak & Sumac

Rashes from plants can appear as itchy or painful, fluid-filled blisters that spread to other areas of the body when touched.

Tips:

• Wash the skin within 30 minutes of exposure (soap + water)

• Apply calamine lotion or hydrocortisone while awaiting your appointment with your doctor.

• If the rash spreads to your face or genital areas or covers more than 25% of your body, go to urgent care and call your doctor.

Sun Allergies (Yes, That’s a Thing!)

Some folks develop itchy bumps or hives in the sun. This can be a sign of polymorphous light eruption (PMLE) or a reaction to photosensitive medications. Lupus can also cause rashes while out in the sun.

Tips:

• Wear sunscreen and reapply every two hours while outside

• Cover up with UPF clothing (clothing with sun protection built in it)

• See a dermatologist if rashes keep showing up after sun exposure

• 
  

 Heat Rashes

Those tiny red bumps in sweaty areas? They are from clogged sweat glands. In dermatology, it is known as miliaria.

Tips:

• Wear loose, breathable fabrics

• Rinse off after being outside

• Keep the skin dry and cool

When to Call Us

• The rash is painful, blistering, or spreading

• You’re experiencing fever, fatigue, or breathing issues (If you have trouble breathing, call 911)

• Over-the-counter treatments aren’t working

Doctor's Tip: Keep a small “skin kit” in your car or bag with hydrocortisone, antihistamines, water, sunscreen, and insect repellent so you’re always prepared.
