INDICATION – DEFINITION
Definition
Uneven skin tone, also known as hyperpigmentation, refers to the irregular darkening of the skin. This condition results in patches of skin that are darker than the surrounding areas due to an overproduction of melanin.
Clinical Factors
- Melasma: A common condition causing brown to gray-brown patches, often on the face. It is influenced by hormonal changes and sun exposure.
- Post-inflammatory Hyperpigmentation (PIH): Occurs following an injury or inflammation of the skin, such as acne, eczema, or psoriasis. The healing process can lead to excess melanin production in the affected area.
- Solar Lentigines: Also known as age or liver spots, these are small, darkened patches caused by long-term sun exposure.
- Freckles (Ephelides): Small brown spots that often become more pronounced with sun exposure, more common in individuals with fair skin.
- Medical Conditions: Certain systemic diseases like Addison’s disease or hemochromatosis can cause changes in skin pigmentation.
Non-Clinical Factors
- Sun Exposure: Ultraviolet (UV) radiation stimulates melanin production, leading to darkening of the skin. Prolonged exposure can cause lasting hyperpigmentation.
- Hormonal Changes: Pregnancy, oral contraceptives, and hormone replacement therapy can cause melasma due to hormonal fluctuations.
- Medications: Certain drugs, such as chemotherapy agents, antibiotics, and anti-seizure medications, can lead to hyperpigmentation as a side effect.
- Skin Care Practices: Incorrect use of skincare products, including over-exfoliation or the use of products containing irritants, can damage the skin and result in hyperpigmentation.
- Genetics: Family history and genetic predisposition play a role in conditions like freckles and melasma.
- Aging: As skin ages, it becomes more susceptible to uneven pigmentation due to cumulative sun exposure and a decline in skin cell regeneration.
Management and Treatment
- Topical Treatments: Hydroquinone, retinoids, and vitamin C are commonly used to lighten hyperpigmented areas.
- Sun Protection: Daily use of broad-spectrum sunscreen with an SPF of 30 or higher is crucial to prevent further darkening.
- Procedures: Chemical peels, laser therapy, and microdermabrasion can be effective in reducing hyperpigmentation.
