Skin Spots and What Causes Them
Do you suffer from skin spots?
To understand what skin spots are and where they come from, first we’ll have to look at what your skin is.
Skin is the largest organ in your body and it covers it completely. It fulfills many functions, some of which are that it:
- Protects your from infections,
- Regulates your body temperature,
- Stores water,
- Stores fat,
- Protects you from heat and light,
- Is a sensory organ.
Throughout your whole body, the characteristics of your skin vary in color, thickness and texture.
What Gives Your Skin Color?
The color of your skin is a physical and genetic feature. Various factors intervene, such as:
- Melanin, the most important. It’s a dark color and its presence is the determining factor of your skin color.
- Hemoglobin, a component of your blood. It gives a red color.
- Carotene, which gives an orange pigmentation.
- Being exposed to ultraviolet rays or radiation.
- Taking certain medications.
Your skin is prone to spots that are different types, shapes, or places. The majority of the spots are harmless and go away by themselves, but it’s good to know where they come for.
Melanin is responsible for giving your skin pigmentation. It’s produced by melanocytes, cells that you find in your epidermis, the top layer of your skin, and has the function of making this pigment.
Melanin is distributed among the other cells, which is how it all looks uniform. This distribution of melanocytes can cause:
- Benign groups: freckles, age spots, and moles.
- Loss of pigmentation, forming white spots, called hypopigmentation.

The Most Common Types of Skin Spots
White Spots, or Hypopigmentation
White spots can have different origins:
- From trauma, burns, or blisters: injuries that exhaust melanin.
- Congenital imbalances, like vitiligo or albinism. Vitiligo can appear as a pale spot in your skin that later spreads to your whole body. Its aesthetic appearance could cause psychological problems in the person that suffers from it.
- As a result of skin inflammation or infection that causes damage to the melanin. This is the case with seborrheic dermatitis, for example.
- From age. These appear with brown spots after your 40’s. It’s unclear why, but it’s believed that they appear due to sun exposure over so many years.
- Birth marks. These are marks from when you’re born, and are abnormal blood vessels in your skin.
- Acne. They mainly appear as pimples on your face. You can see them mostly on teenagers.
- Angiomas or papules. They are blood vessels that group together and form bumps. They can form on the outer layer of the skin or deeper down.
- Allergic reaction. These outbreaks can be caused by different allergens, like food, makeup, medications, etc.
- Petechiae. They form from tiny blood vessels breaking under your skin and look like little red spots.
- Heat rash. In hot places, sweat gets trapped under your pores and little red marks appear.
- Sicknesses. There are more serious problems that cause redness in your skin such as chicken pox, lupus, bruises or syphilis, among others.
These spots are darker and are formed by higher amount of melanin than the rest of your skin.
Generally, they aren’t harmful to your health and they only affect appearance, depending on where they are and how big they are. You may be born with some, whike others appear over time.
