ARMPIT RASH AND IRRITATION

Ranging from a simple and common underarm rash from shaving to a more severe fungal rash, underarms are highly-prone to being affected. In this ideal warm and dark environment, when not properly controlled, bacteria often thrives for an unwelcome period of time.

Problems with underarm skin irritation and rashes can vary from mild cases, through extremely cumbersome and all the way to downright scary occurrences. With a wide variety of factors affecting the underarm skin, knowing what you are looking at is the first step to dealing with the underlying problem. Some of causes can include heat, allergens, immune system disorders, various infections and different medications. Many of the instances are closely connected with body sweat and bacteria that forms in its presence. Visit Sweat and Body Odor to learn more about this process.

Paying close attention to your body and taking proper precautions is an important part of getting ahead of underarm irritation and rashes and minimizing their uninvited appearance. 

Contact Dermatitis (appears in three forms)

1. Allergic Contact Dermatitis
   Allergic reaction to an ingredient that causes an immune system to respond and affect the skin. In this instance, a person may not be able to use a product due to its composition. Allergic contact dermatitis occurs when a certain ingredient in a product comes in contact with skin, triggering an allergic reaction.
   
   Common culprits may include ingredients in soaps, fragrances and other cosmetic products. If you have an allergy to a specific ingredient, you should avoid products containing it.

2. Irritant Contact Dermatitis
   Inflammation of the skin that occurs when particular substance directly damages the outer layer of the skin or interrupts skin's pH level.
   
   One example that we see with natural deodorants is a skin irritation when person’s body pH reacts poorly due to baking soda's alkaline properties. Please visit our page What's the Deal with Baking Soda and Underarms.

3. Phototoxic Contact Dermatitis
   Presents itself after a person’s skin is exposed to light; this chemically induced reaction mimics how the body reacts when skin is sunburned.

Heat Rash

Otherwise known as Miliaria or prickly heat, heat rash is a skin condition marked by small, itchy red marks occurring in hot and humid conditions. This is a common disorder of the eccrine sweat glands that occurs during times of increased humidity and heat. It can develop when sweat glands get plugged by dead skin or by infection from Staphylococcus epidermidis.

Intertrigo
Intertrigo is an inflammation of the body folds. Because the underarm area has skin folds and generally isn’t exposed, too much sweat can build up, causing an uncomfortable irritation. The skin-to-skin friction that takes place as you move about your day and/or your genetic predisposition can activate bacterial and yeast infections.

 

Following proper cleansing, regular exfoliation, control of the odor causing bacteria and finding right products for your skin type can be a first step towards your overall underarm health.
