Uneven Skin Tone

Types of Uneven Skin Tone

1. Freckling:

Freckles are tiny dark spots that appear on the surface of the skin, usually due to sun exposure. They are more common in individuals with fair skin, but they can also occur in darker skin types. Freckles are harmless and tend to fade or disappear over time.

2. Melasma:

Melasma is a common skin condition characterised by dark patches on the face. It is more common in women, especially those with darker skin types. Melasma can be caused by hormonal changes, sun exposure, pregnancy, and the use of certain medications.

3. Chloasma:

Chloasma is another form of hyperpigmentation that causes brown or gray patches on the skin. It is similar to melasma but tends to occur in different areas on the face, such as the cheeks, bridge of the nose, and forehead. Chloasma can be caused by hormonal changes, sun exposure, and certain medications.

4. Post-inflammatory hyperpigmentation:

Post-inflammatory hyperpigmentation is a skin condition that occurs after the skin has suffered an injury or inflammation. It can occur following acne breakouts, burns, or scars. This type of hyperpigmentation is more common in individuals with darker skin types.

Causes of Uneven Skin Tone

1. Sun Exposure:

Prolonged exposure to the sun’s UV rays is one of the leading causes of uneven skin tone. It triggers the production of melanin, which gives the skin its natural colour. Overexposure to the sun can lead to sun damage, including dark spots, melasma, and premature ageing.

2. Genetics:

Uneven skin tone can also be genetically inherited. Certain skin types are more susceptible to hyperpigmentation, such as darker skin types. It is more common in individuals with a family history of hyperpigmentation.

3. Hormonal Changes:

Hormonal changes, such as those due to pregnancy, birth control pills, or menopause, can also cause uneven skin tone. These hormonal fluctuations can affect the production of melanin, leading to changes in skin colour.

4. Medications:

Certain medications, including those used to treat acne and high blood pressure, can cause hyperpigmentation as a side effect. It is important to discuss any skin changes with a healthcare professional, as they may recommend alternative medications or treatments.

5. Acne:

Acne breakouts can lead to post-inflammatory hyperpigmentation, particularly in patients with darker skin types. The inflammation caused by acne can cause the skin to produce more melanin, resulting in darker scars or dark spots.

6. Skin Infections:

Certain skin infections, such as fungal infections or folliculitis, can cause uneven skin tone. The inflammation or irritation associated with these infections can lead to hyperpigmentation.

7. Chemical Peels:

Some chemical peels, especially those used to treat acne, can cause temporary hyperpigmentation. This is typically a temporary side effect and resolves over time as the skin heals.

8. Environmental Factors:

Exposure to environmental toxins, such as cigarette smoke or pollution, can contribute to uneven skin tone. These pollutants can irritate the skin and trigger the production of melanin, leading to discolouration.
