📚 Understanding Melasma
Melasma is a common skin condition characterized by brown or gray-brown patches, usually on the face. It's often triggered by hormonal changes, such as those experienced during pregnancy or while taking birth control pills.
☀️ Understanding Sunspots (Solar Lentigines)
Sunspots, also known as solar lentigines, are small, darkened patches on the skin that develop due to sun exposure over time. They are a sign of sun damage and are more common in older adults.
