Intertrigo: What Is It and How Can You Help Relieve It?

Intertrigo refers to skin inflammation localised in areas of friction, particularly skin folds. It results from maceration caused by heat, moisture, and mechanical friction. These conditions can cause skin irritation, leading to persistent redness or even skin erosion.

There are two main forms :

• Non-infectious intertrigo, associated with irritation, eczema, contact allergy, toxic dermatitis, or certain dermatological conditions (inverted psoriasis, Hailey-Hailey disease).

• Infectious intertrigo, caused by the proliferation of fungi (Candida albicans, dermatophytes), yeasts, or bacteria (particularly corynebacteria).

Is it contagious?

Intertrigo itself is not considered a contagious condition. However, if a secondary bacterial or fungal infection occurs, some of the involved germs may be contagious. It is therefore recommended to avoid sharing clothing or shoes.

Which areas are most commonly affected?

Intertrigo primarily affects two types of skin folds:

• Small skin folds: The spaces between the fingers and toes, the buttocks, or the skin folds of infants.

• Large skin folds: including the groin, under the breasts, and under the arms.

Several forms of intertrigo can occur, including "athlete's foot," which affects the toes.

This variant, known as dermatophytosis, is often linked to sweaty feet, creating an environment conducive to intertrigo and fungal infection.

How to recognize inguinal intertrigo?

Inguinal intertrigo develops in the folds of the groin, on the inner thighs, or near the anal region. These areas are particularly prone to moisture, heat, and friction, making them ideal for the development of this skin condition.

The onset of intertrigo is often multifactorial. Certain conditions can contribute to or worsen its development.

Environmental causes

It has been observed that heat, ambient humidity, and poor ventilation of exposed skin areas can promote maceration. Wearing closed-toe shoes, tight clothing, or synthetic underwear can also be an aggravating factor.

Causes Related to Individual Factors

People with obesity, diabetes, excessive sweating, or urinary incontinence are more likely to develop intertrigo, as are infants in diapers and immunocompromised individuals.

Behavioral causes

Inadequate hygiene (either too much or too little), certain sports, and prolonged wear of damp or tight-fitting clothing can contribute to the development of this skin irritation.

• Redness in skin folds (2) (3)

• Discomfort: tingling, a burning sensation, or increased discomfort when rubbed. (2) (3)

• Damaged skin: flaking (peeling skin), oozing, or cracked appearance. (2) (3)

• Presence of small pustules: in some cases, especially in the context of an infection. (2) (3)

Only a healthcare professional (dermatologist) can make an accurate diagnosis. Conventional treatments may be recommended, such as drying creams, antifungal or antibiotic creams, or hydrocortisone-based creams, depending on the identified cause. A consultation will be necessary to obtain the appropriate cream.

Focus on Organic Aloe Vera Gel

• Pure aloe vera gel is known for its soothing, moisturising, and mildly anti-inflammatory properties on irritated or heated skin.

• It can help relieve feelings of tightness, heat, or discomfort in non-infected skin folds.

• Thanks to its watery texture, it promotes hydration without an occlusive effect.

Aloe vera can be used occasionally to provide comfort to irritated skin in the non-infectious phase, provided that:

• Thoroughly dry the area before application.

• Use a pure gel, free of fragrance and irritating preservatives.

• Do not apply under a bandage or occlusive clothing.

If inflammation occurs, consult a doctor.

It is important to remember that a medical diagnosis is always preferable when in doubt. At the same time, there are a few common-sense steps you can take:

1. Gently pat the skin folds dry after bathing, without rubbing.

2. Choose showers over baths.

3. Wear loose-fitting, breathable clothing (cotton, linen).

4. Use a mild, unscented soap.

5. If you sweat heavily, change your clothes regularly.

6. In summer or in hot weather, keep sensitive areas as cool as possible.

Noticing the first signs of discomfort in skin folds can allow you to take action quickly. Keeping a diary of when symptoms appear can also help identify individual triggers.
