What makes dark skin unique from all other skin types is melanin, a naturally-occurring pigment found just underneath the skin's surface. While everyone's skin has melanin to some degree, dark skin types have more creating richer colors in a variety of shades.
A plus side to having darker skin is greater resistance to sunburns, photo-aging and skin cancer since melanin naturally absorbs some ultra violet radiation (this doesn't mean you get to skip out on sunscreen though). But a downside is more noticeable skin discoloration.
What is it?
Skin discoloration comes in two forms: loss of pigment (hypo-pigmentation) and excessive pigment (hyper-pigmentation). It can be small like freckles, or big like patches that connect across areas of the body. Either way, common causes are skin damage, sun damage, genetics, or skin disorders.
To keep your complexion as smooth and even as possible, try avoiding any behaviors that can damage it like picking at blemishes, forgetting to wear sunscreen, and ignoring irregularities that could signal a more serious condition. Mild cases of skin discoloration can be treated at home by using products like glo therapeutics Brightening Serum or Lightening Serum to help balance pigmentation. But for more pressing cases, do not hesitate to contact a skincare professional.
