Intertrigo is a skin condition that causes a rash on the buttocks, inner thighs, groin and inner male thigh. Intertrigo rash occurs when blocked sweat ducts cause irritation and itchiness of the skin.

What is Intertrigo Rash?

Intertrigo is a rash caused by heat, moisture and friction. It’s very common in overweight people and can be triggered by wearing tight clothing or staying in one place for long periods of time. Intertrigo can also occur if you have an open wound on your body. If you have other skin conditions like eczema, psoriasis or dermatitis that affect your skin, they may make it easier for bacteria to get under the surface of your skin where they will cause an infection called cellulitis (a type of bacterial infection).

What causes Intertrigo Rash?

The cause of intertrigo rash is not clear, but it is thought to be caused by friction and sweat. The warm, moist skin of the groin area may be more prone to irritation or inflammation than other parts of your body.

Intertrigo Rash Causes: Warmth and Moisture

The most common cause of intertrigo rash is sweating in this area due to heat or prolonged exposure to high temperatures. This can result in irritation from the friction between clothing against your skin as well as bacterial infections (which are often present on the clothes).

How to prevent Intertrigo Rash?

To prevent Intertrigo Rash, you need to keep your skin clean and dry. If you don’t, the heat generated by friction can lead to irritation of the skin. Make sure that you wear loose clothing so that there is no friction on the body part affected by Intertrigo Rash. This will help in keeping your body warm as well as preventing further irritation of your body parts.

To keep the skin dry, apply an emollient cream or lotion after bathing every day at least twice a week or once every two days if it’s very humid outside (or in).

How to treat Intertrigo Rash?

The most effective treatment for intertrigo rash is to treat it with corticosteroids. This can be done by applying a topical antibiotic ointment, such as mupirocine or clotrimazole, to the affected areas of your skin.

If you have heard of a remedy called “humidifying,” there’s good news: it works! Humidifiers help keep your skin moist and prevent dryness from occurring by increasing the amount of water absorbed into the pores on your body’s surface.


The takeaway is that you can prevent intertrigo rash by:

  • Using a moisturizing soap or cleanser to wash your skin regularly.
  • Using an anti-itch cream when the rash starts to flare up.

If you’re already experiencing symptoms of an intertrigo rash, take these steps:

  • Use an emollient cream or lotion on the affected area twice daily until it heals (or as directed by your dermatologist). You should also apply it to your lower legs as well since they’re often where intertrigo rashes tend to develop first.


Intertrigo is a rash that occurs most commonly on the elbows, knees and feet. It can be caused by an allergic reaction to something in the environment or your own skin. If you have Intertrigo Rash, it’s important to keep your skin clean and moisturized so it doesn’t get infected. To treat this condition, apply medicated lotion before bedtime and alternate between soaps of different kinds until your symptoms subside completely.
