Melanin is naturally present in our skin, hair, and eyes, acting as a protective pigment. It is neither inherently good nor bad, but serves key roles in our bodies. Positively, melanin blocks harmful UV radiation, reducing the risk of skin cancer and sunburns. Moreover, it contributes to the diversity of skin tones globally. However, an imbalance can lead to conditions like vitiligo or hyperpigmentation. Maintaining skin health through sunscreen and proper care is crucial for everyone, regardless of melanin levels.
