Intertrigo is a common inflammatory skin condition that develops when skin rubs against skin in warm, moist areas of the body. The friction, trapped moisture, and lack of airflow can leave the skin feeling red, itchy, sore, and uncomfortable.
Although intertrigo can happen to anyone, it is especially common in areas where sweating and skin-to-skin contact occur regularly.
In this guide, we’ll cover:
- what intertrigo is
- common symptoms and causes
- how to soothe irritated skin naturally
- products and fabrics that may help reduce friction and moisture
Please note: severe, worsening, or infected rashes should always be evaluated by a healthcare professional.
What Is Intertrigo?
Intertrigo is an inflammatory rash that forms in skin folds where friction and moisture become trapped. Common areas include:
- under the breasts
- armpits
- groin area
- inner thighs
- abdominal folds
- between the buttocks
- neck folds
- between toes or fingers
When skin repeatedly rubs together, the skin barrier becomes irritated and damaged. Heat and moisture can then make the area even more inflamed.
In some cases, yeast or bacteria may begin growing in the irritated area, worsening symptoms.
Symptoms of Intertrigo
Intertrigo symptoms can range from mild irritation to painful inflammation.
Common signs include:
- red or reddish-brown rash
- soreness or tenderness
- itching
- burning sensation
- cracked or peeling skin
- oozing skin
- unpleasant odor
- moist or shiny skin
- discomfort during movement
Because intertrigo develops in sensitive skin folds, symptoms can become uncomfortable quickly if moisture and friction continue.
What Causes Intertrigo?
The main causes of intertrigo are:
- skin rubbing together
- trapped sweat or moisture
- heat
- lack of airflow
- friction from clothing
- prolonged dampness
Certain factors may increase the likelihood of developing intertrigo, including:
- hot or humid environments
- exercise and sweating
- excess skin folds
- tight clothing
- immobility
- diabetes
- weakened skin barrier
- sensitive skin conditions like eczema
Can Intertrigo Become Infected?
Yes. Because the skin barrier becomes damaged, intertrigo can sometimes lead to secondary fungal or bacterial overgrowth.
Signs you should speak with a healthcare professional include:
- worsening redness
- swelling
- strong odor
- pus or drainage
- fever
- spreading rash
- severe pain
Best At-Home Treatments for Intertrigo
Keep the Area Clean and Dry
One of the most important parts of managing intertrigo is reducing excess moisture.
Wash affected areas gently with lukewarm water and avoid heavily fragranced soaps or harsh cleansers that may further irritate the skin.
We recommend the Nourish + Hydrate Cleansing Bar because it cleanses sensitive skin without leaving it feeling stripped or overly dry. Made with only 3 minimal ingredients, it’s a gentle option for irritated skin folds.
After cleansing, gently pat the skin dry rather than rubbing.
Reduce Friction
Continuous rubbing prevents the skin from calming down and healing comfortably.
Form fitting, yet breathable fabrics may help reduce irritation and allow better airflow to the area.
Remedywear garments are especially helpful for sensitive skin because they are made with soft TENCEL and zinc-embedded fibers designed for irritated, reactive skin. The lightweight fabric fits like a second skin and helps reduce rubbing while remaining breathable and comfortable for daily wear.
For areas prone to moisture and friction, some people prefer wearing form fitting lightweight layers, like these underneath regular clothing.
Soothe Hot, Irritated Skin
Inflamed skin folds can sometimes feel hot, itchy, or painfully irritated.
Many people find cooling, minimal-ingredient skincare more comfortable during flares.
Emily Skin Soothers Hot Skin Soother is often used on irritated, itchy-feeling skin because it contains gentle botanical ingredients traditionally used to comfort sensitive skin.
Avoid applying heavily fragranced lotions or products containing alcohol to already inflamed areas.
Wear Breathable Clothing
Heavy fabrics and tight-fitting clothing can trap heat and sweat against the skin.
To help reduce irritation:
- wear loose-fitting clothing
- change out of sweaty clothing quickly
- avoid rough seams or tight elastic
- choose breathable fabrics whenever possible
Moisture-wicking fabrics may also help keep skin folds drier throughout the day. 100% cotton clothing is an excellent option and super breathable.
Our Final Thoughts on Treating Intertrigo
Intertrigo can be uncomfortable, painful, and frustrating, especially in warm weather or areas where skin constantly rubs together.
The good news is that many cases improve when you focus on reducing moisture, minimizing friction, and supporting the skin barrier with gentle skincare and breathable fabrics.
Keeping the area cool, dry, and protected can go a long way toward helping irritated skin feel more comfortable.
