Different Types of Skin Patches and how to differentiate them!

Different types of skin patches with discolored skin are common and have many diverse causes, which include birthmarks, pigmentation disorder, rashes, and skin infections. Some causes are harmless, but others will have to need medical attention. The skin contains melanin, which is the pigment that gives color to our skin.

Having more melanin makes our skin color darker, while less of it gives us a lighter skin color. Patches of discolored skin are visible because they are different from a person’s usual skin color. As a doctor, I advise it is significant that people with this symptom recognize the cause of their discolored skin patches in case treatment is essential.

Different Types of Skin Patches and how to differentiate them!

Let us look at some of the common factors for different types of skin patches.

  1. Birthmark – A birthmark is a colored mark on or under the skin that’s present at birth or builds up soon after birth. Some birthmarks become paler with time while others become more distinct. The majority of birthmarks are unproblematic and painless.
  2. Skin Pigmentation disorders: if you have lighter or darker skin patches, this could indicate a skin pigmentation disorder. Kinds of skin pigmentation disorder include:
  3. Melesma: A common skin issue that typically affects facial skin and results in brown patches. More often it affects women. The trigger of melasma is sun exposure and hormonal imbalance.
  4. Vitiligo: It causes the cells that produce melanin, known as melanocytes, to stop functioning properly, which forms patches of lighter skin.
  5. Post-inflammatory hyperpigmentation or hypopigmentation: A temporary boost or diminish in skin pigment following skin trauma, such as a blister, burns or wounds
  6. Albinism: People with albinism do not generate enough melanin. This leads to very less or no pigment in the skin. Albinism is a genetic disorder.
  7. Skin rashes

Some types of skin rash can also result in patches of discolored skin. These include:

  1. Rosacea: This is an unceasing skin issue that can cause patches of red skin and pus-filled lesions.
  2. Contact dermatitis: This rash occurs when the skin reacts to an irritant or allergen.
  3. Eczema: This condition can cause patches of red skin which is also itchy, dry, and cracked.

When to see a doctor?

If a new patch of discolored skin comes into sight and does not go away, it is best to see a doctor. It is also significant to ask for medical attention the patch changes size, shape, or texture.
