By No, the sun is not the only cause of skin spots. While sun exposure is a common cause of skin spots, there are several other factors that can contribute to their development. Some additional causes of skin spots include:
Hormonal Changes: Hormonal fluctuations during pregnancy (melasma or “pregnancy mask”) or while taking certain hormonal medications can lead to the development of dark patches or spots on the skin.
Aging: As we age, the production and distribution of melanin in the skin may become irregular, resulting in age spots or liver spots, particularly in areas exposed to the sun.
Post-Inflammatory Hyperpigmentation (PIH): Skin inflammation or injury, such as acne, eczema, psoriasis, or cuts and wounds, can cause dark spots to develop as part of the healing process.
Genetic Factors: Some individuals may be genetically predisposed to certain types of hyperpigmentation, such as freckles or birthmarks.
Skin Conditions: Certain skin conditions like melasma, lentigines, or post-inflammatory melanosis can cause the formation of skin spots.
It’s important to note that skin spots can also be a symptom of underlying medical conditions or skin disorders. If you notice any changes in your skin, it is advisable to consult a dermatologist for a proper diagnosis and appropriate treatment.
