Besides acne, skin rashes are one of the most common indications in medical dermatology. In this blog, we will look at some of the most common causes of skin rashes and look at specific treatments to help you on your journey.
What are rashes?
Before looking at causes and skin rash treatment, it helps to understand what a rash is. Rashes are often referred to as dermatitis and typically manifest as a significant change to the overall texture of the skin, redness, and/or raised lumps or spots.
Some rashes – known as contact dermatitis happens because of the skin coming into contact with specific substances, including:
- Chemicals (including latex, rubber, and elastic)
- Cosmetics (including soaps, perfumes, and detergents)
- Dyes and chemicals from clothing etc
- Poison ivy, oak, or sumac
Other rashes are caused by specific medical conditions such as:
- pityriasis rosea
Now, dermatitis can often be identified by how it looks and the symptoms that accompany it. However, it can be difficult to pinpoint exact causes without the help of an expert.
More challenging rashes may require further investigation by a trained professional. Here at Dr. Jinah Yoo Dermatology, we provide a full range of medical investigations to help diagnose and treat skin rashes.
Skin Rash Biopsy – This involves taking a small sample of the skin to assess it under a microscope.
Skin Scraping - If we suspect it is a fungal/yeast infection causing the skin rash, we may recommend skin scraping. This helps us to determine exactly what substance is causing the rash and prescribe antifungal medication.
Blood tests - Our experts will take a sample of your blood to be analysed by a lab. This will help us to identify any underlying medical conditions that could be causing the rash.
Most simple rashes will improve with gentle skin care, and the use of antihistamine medication and other calming substances.
To help treat skin rashes quickly and effectively, we recommend following the below guidelines:
- Stop using any new products you may have introduced
- Avoid itching where possible
- Use gentle cleansers to avoid further irritation
- Avoid applying cosmetic products directly on the rash
- Pat with warm water for cleaning
- Leave the affected area exposed to the air as much as possible
- Try applying calamine medicated lotion for contact dermatitis
Now, if your rash has required specific tests, depending on your results we will recommend a specific treatment plan that is tailored to your specific needs. This may include:
- Prescription medication
- Combination treatment
