Introduction to skin discoloration
Our world is a mixture of different kinds of people. We may have come across a person with uneven skin color. Skin is the largest organ of our body and covers us from head to toe. The color found on the skin is due to a pigment called melanin. It is a complex polymer derived from tyrosine (an amino acid) and is found in melanocytes cells. Epidermis, the top layer of our skin, is where the melanocytes are distributed. Whenever melanin is produced it spreads to the skin cells nearby and tries to bring about a uniform skin color. Discoloration of the skin can happen when there is too much, too little or no melanin present. Melanocytes can also form groups or nests that lead to freckles, moles, age spots or other kinds of discoloration. There are different types of skin discoloration treatment available on the market today, all has its pros and cons so it’s better to check for the best suits your skin.
Causes of skin discoloration
Skin discoloration can develop from a grouping of blood vessels or funguses. Some of the common causes are injury, illness or inflammatory problems. Basically, a difference in the melanin level can bring about skin discoloration in the neck, face, and legs. Skin infections cause localized changes in skin color and texture. Fungal infections like candida, tinea versicolor, and ringworm cause skin discoloration.
- Burns: A burn on the skin tissue causes a change in skin color. It can be a sunburn or a skin burn varying from first-degree to the third-degree. Uneven application of sunscreen leads to a patchy tan. Healing of a skin burn leads to the formation of a scar tissue that is not of the same skin color causing in discoloration.
- Hormonal changes: Hormonal changes in the body lead to skin discoloration on the face or neck. During pregnancy, the increase in the levels of estrogen and progesterone cause dark colored patches of skin. Melasma or the mask of pregnancy is a condition where dark patches of skin develop on both sides of the face or the neck(rare) due to the hormone level change in the body in pregnant women (chloasma).
- Autoimmune disease and allergy: Autoimmune disease and allergy can also be a cause for this condition. The immune system attacks the healthy cells and causes inflammation that leads to discoloration. Diseases like lupus erythematosus and Grave’s can cause skin lightening or darkening. Allergy-like eczema causes scaly patches and red bumps on the skin. Various allergic reaction to foods, irritants or plants can cause discolored skin patches.
- Birthmarks: Birthmarks develop at birth or after birth and are discolored spots. Some of the different types of birthmarks found are moles (brown or black in color), strawberry nevus (red color) and Mongolian blue spots (blue patches on the skin).
- Skin Cancer: Skin cancer occurs when our DNA inside the cells get damaged due to long-term sun exposure or chemical exposure. Damaged cells start growing out of control to form a mass of cells. Some types are basal cell carcinoma, squamous cell carcinoma, actinic keratosis (brown or pink spots on the hands or face) and melanoma (cancerous mole found on the chest or back in men and on the legs in women).

Sometimes, it will also change a person’s hair color. The exact cause of vitiligo is unknown but is often linked with suppressed immune.
- Post-inflammatory hyperpigmentation or hypopigmentation: There is an increase or decrease in skin pigmentation following skin trauma, such as a blister or burn.
- Albinism. People with albinism do not produce enough melanin. This leads to little or no pigment in the skin, hair, or eyes. Albinism is a genetic disorder, meaning that a person inherits a faulty gene from one or both of their parents.
- Some other causes are contact dermatitis, rosacea (red bumps on nose, forehead or cheek), radiation therapy, stasis ulcer (occurs in lower legs) and vitiligo (white patches on the skin due to non-functioning melanocytes).
