Common Dyschromia Causes,Treatments and More


Dyschromia is a condition characterized by abnormal skin coloration. It can manifest as dark patches surrounded by lighter skin or uneven pigmentation. In this article, we will explore the common causes of dyschromia, available treatments, scientific evidence of their efficacy, as well as potential benefits and side effects.

What is Dyschromia

To understand dyschromia, we need to delve into the science behind our skin's coloration. Our skin contains melanocytes, specialized cells that produce melanin, the pigment responsible for skin color. The amount of melanin determines the darkness or lightness of our skin. Dyschromia occurs when there is an irregularity in the uniformity of pigmentation.

Common Dyschromia Causes

1. Freckles: Small brown spots that appear due to an increased concentration of melanin in certain areas of the skin.
2. Age spots or liver spots: Dark patches that develop as a result of sun exposure over time.
3. Lentigines: Flat, tan to brown spots caused by an increase in melanocytes.
4. Melasma: Dark patches that commonly occur due to hormonal fluctuations, often during pregnancy or with the use of certain medications.
5. Chloasma: Similar to melasma, chloasma is a type of dyschromia that results from hormonal changes, such as those experienced during pregnancy.
6. Basal cell carcinoma and squamous cell carcinoma: Certain types of skin cancer can cause dyschromia.
7. Minor skin injuries: Cuts, scrapes, or wounds can lead to temporary dyschromia.
8. Medication-induced photosensitivity: Some medications can make the skin more sensitive to sunlight, resulting in dyschromia.
9. Insect bites: Inflammatory reactions to insect bites can cause temporary dyschromia.
10. Bathing trunk nevi and giant nevi: Congenital birthmarks that can cause irregular pigmentation.
11. Sunburn: Excessive exposure to the sun's UV rays can lead to temporary dyschromia.
12. Skin infections: Certain skin infections can cause dyschromia as a secondary effect.
13. Melanoma: A type of skin cancer that can cause dyschromia.
14. Vitiligo: A condition where the skin loses pigmentation, resulting in white patches.

Treatments for Dyschromia

The treatment options for dyschromia vary depending on the underlying cause and severity of the condition. It is essential to consult with a dermatologist to determine the most suitable treatment approach. Some common treatments include:

1. Topical creams: Dermatologists may prescribe creams containing ingredients like hydroquinone, retinoids, or corticosteroids to lighten dark patches and even out skin tone.
2. Chemical peels: This procedure involves applying a chemical solution to the skin to exfoliate and improve pigmentation irregularities.
3. Laser therapy: Laser treatments can target specific areas of dyschromia and stimulate the production of new, evenly pigmented skin cells.
4. Microdermabrasion: This procedure exfoliates the superficial layers of the skin, reducing the appearance of dyschromia.
5. Cryotherapy: In some cases, freezing the affected area with liquid nitrogen can help improve dyschromia.
6. Phototherapy: Using controlled exposure to ultraviolet light, phototherapy can help restore pigmentation in some cases of dyschromia.

Scientific Evidence, Benefits, and Side Effects

Numerous studies have explored the efficacy of different treatments for dyschromia. However, it is important to note that individual responses may vary. Scientific evidence suggests that treatments such as topical creams, chemical peels, laser therapy, and cryotherapy can effectively improve dyschromia in many cases.

Benefits of treatment can include improved self-confidence, a more even skin tone, and reduced visibility of discolored patches. However, it is crucial to consider potential side effects. These can include temporary redness, irritation, or sensitivity to the treated area. In rare cases, more severe side effects may occur, such as scarring or infection. Your dermatologist will discuss these risks and benefits with you before proceeding with any treatment.


Dyschromia, characterized by abnormal skin coloration, can have various causes and manifestations. Understanding the underlying causes is crucial in determining the appropriate treatment options. Dermatologists can recommend treatments tailored to individual needs, which may include topical creams, chemical peels, laser therapy, or other interventions. While treatments have shown scientific evidence of efficacy, it is important to weigh the potential benefits against the possible side effects. Consulting with a dermatologist is key to achieving optimal results and improving skin pigmentation irregularities caused by dyschromia.
