Contact dermatitis is a rash caused by your skin reacting to a substance it has come into contact with. You may need patch testing to identify the causative substance. A steroid cream or ointment will usually clear the rash. However, the long-term treatment is to avoid contact with the agent that’s causing it.
There are two types of contact dermatitis – irritant and allergic.
Irritant contact dermatitis
This is caused by direct contact with a substance which irritates the skin. It most commonly affects the hands.
Allergic contact dermatitis
This occurs when your immune system reacts against a specific substance (allergic skin reaction).
Many substances can cause an allergic contact dermatitis. Common ones include:

Types of hyperpigmentation
There are several types of hyperpigmentation, the common ones being melasma, sunspots, and post-inflammatory hyperpigmentation.
What causes hyperpigmentation?
A common cause of hyperpigmentation is an excess production of melanin. Melanin is a pigment that gives skin its colour. Several different conditions or factors can alter the production of melanin in your body.
Certain medications can cause hyperpigmentation. Also, some chemotherapy drugs can cause hyperpigmentation as a side effect.
Pregnancy changes hormone levels and can affect melanin production in some women.
Excessive sun exposure can also cause an increase in melanin.
There are many other causes for darkening of the skin. It is best to consult you dermatologist for a clear diagnosis.
How is hyperpigmentation diagnosed and treated?
A dermatologist can diagnose the cause of your hyperpigmentation. They will request your medical history and give you a physical examination to determine the cause. In some cases, a skin biopsy can narrow down the cause.
Treatment should be discussed with your dermatologist.

It’s not always possible to prevent hyperpigmentation. However, you can protect yourself by:
