Sun Exposure: UV rays stimulate melanin production, exacerbating dark patches and spots.
Hormonal Changes: Pregnancy, birth control pills, or hormonal imbalances can trigger melasma.
Skin Inflammation: Conditions such as acne, eczema, or injuries can cause post-inflammatory hyperpigmentation.
Genetics: A family history of melasma or hyperpigmentation increases the likelihood of developing these conditions.
Aging Process: Natural aging can lead to uneven melanin distribution, resulting in age spots or dark patches.
