Why Skin Gets Darker in Summer – Dermatologist Guide
Many people notice their skin becoming darker during summer. This is mainly due to increased sun exposure and higher UV radiation levels. While tanning is a natural protective response of the skin, excessive exposure can lead to pigmentation and long-term skin damage.
Why Skin Gets Darker in Summer
During summer, the sun emits stronger ultraviolet (UV) rays. These rays stimulate melanin production in the skin. Melanin is the pigment responsible for skin color. When melanin increases, the skin appears darker.
This process is the body's natural defense mechanism against sun damage.
What is Skin Tanning
Skin tanning occurs when UV rays penetrate the skin and trigger melanocytes to produce more melanin. This extra melanin spreads across the skin, causing darkening.
Although tanning may look temporary, repeated exposure can cause permanent pigmentation.
Common Causes of Summer Darkening
