Possible causes

It is important to note that the skin folds can hold moisture, fungus and bacteria which can progress into a bacterial infection such as atopic dermatitis or a fungal infection such as athlete’s foot or a yeast infection. The individual can also suffer from contact allergic dermatitis by using a particular soap, body spray or lotion. In some cases, folliculitis can also develop in which the ingrown hairs develop under the skin fold.


Some forms of rashes such as atopic dermatitis tends to clear up on its own with modifications to the hygiene measures and wearing suitable clothing. By keeping the affected area clean and dry, it will help guarantee that the rash will clear up. Overly tight clothing that does not allow the skin to breathe and traps moisture should be avoided.

The individual should also avoid using body sprays and lotions that might be responsible for causing the rashes. In some cases, conditions such as athlete’s foot or yeast infection can be managed with over-the-counter anti-fungal creams, but a doctor should be consulted first.

Considerations to bear in mind

If the affected area is dry and clean at all times and the necessary changes have been carried out but the rashes are still present, it would require prescription-strength medications.

Remember not to allow the rashes to spread deeper into the underlying skin tissues since this can cause deep scar tissue. The individual must be instructed not to scratch the rash.
