Have you ever noticed darker patches or freckles appearing on your skin and wondered why? That’s hyperpigmentation in action a common (and completely normal) shift in pigment production that affects people of all ages and skin tones.

Normally, melanin is evenly distributed, giving skin its consistent tone. But if production or distribution becomes uneven, patches of darker skin appear. So basically let's think of it this way, your skin has colour-making cells called melanocytes, and melanin is part of that system, acting like a protective shie...
