2. Hyperpigmentation

3. Dermatitis

4. Acne

The correct answer is: Hyperpigmentation

Solar lentigines are a type of hyperpigmentation that occurs due to prolonged exposure to ultraviolet (UV) light, particularly from the sun. They are often referred to as "sun spots" or "age spots" and present as small, darkened patches on the skin. These spots are a direct result of melanocyte stimulation leading to an increase in melanin production, which causes localized darkening of the skin. The phenomenon occurs because the skin's response to UV radiation includes the development of these pigmented lesions as a protective mechanism, aiming to absorb and dissipate UV radiation. Over time, as a person is exposed to the sun, these patches may become more prominent, particularly in areas frequently exposed, such as the face, hands, shoulders, and arms. Understanding that solar lentigines are classified under hyperpigmentation is crucial for estheticians, not just for diagnosis, but also for formulating effective treatment plans, which may include methods like chemical peels, laser therapy, or topical agents designed to lighten hyperpigmented areas. This knowledge plays a significant role in skin health management and client education.
