Yes—melanin plays a key role in shielding the skin from harmful ultraviolet (UV) radiation. Acting as the skin’s natural defense system, melanin absorbs and disperses UV rays before they can penetrate deeper layers and damage DNA. This protective pigment helps reduce the risk of sunburn, premature aging, and skin cancer.
However, melanin’s protection isn’t absolute. While those with higher melanin levels do have more built-in defense, no skin type is immune to UV damage. That’s why even with this natural barrier, daily sun protection—like broad-spectrum sunscreen—is still essential for maintaining healthy, resilient skin.
Curious how melanin works on a cellular level and what it really means for your skin health? Keep reading to explore the science behind this powerful pigment.
