One of the ways the human body manifests its intelligent structure is its innate capability to protect itself—even from the deadly penetrating rays of the sun.
Melanin stands as the body’s first line of defense against Ultraviolet Rays because it is a protective pigment produced by Melanocytes or melanin producing cells found in the outer layer of the skin, the epidermis. No doubt the UV rays can sink in deeply to inflict cellular damage but the structure of the melanin inhibits the rays from going deeper.
This is why during excessive sun exposure; the body produces more melanin which results to a darker shade that some mistake as a healthy sun tan.
People of the multi-cultural community do have more melanin pigments in the body resulting in brown to rich-melanin dark skin but that does not give them the leverage of ensured protection against the sun.
Absolutely no skin type or complexion is exempted from having a sun burn, which is an indication that the skin’s melanin, no matter how dominant it is doesn’t work as a foolproof sun protection. In fact, a sun burn is already an indication that the UV rays are too much from what the melanin in the skin can handle.
Melanin plays a crucial role in the skin more than a pigment that dictates the skin’s color and acts as a basic sunscreen. Its unbalanced production or the lack of it is the source of many skin problems.
For example, those who have lighter skin tones are prone to freckles because of the lack of melanin and when these freckles are exposed to the sun they become darker spots. Albinism is the result of the melanocytes not producing melanin which results to less pigmentation as evident in the pale skin. Vitiligo occurs when the melanocytes skip melanin production in specific parts of the body as evident in the white patches.
On contrary cases, melasma is a result of an overproduction in melanin. Sun exposure aggravates the condition by stimulating the melanocytes to produce more melanin.
Sun exposure is damaging to the skin in many ways as the melanin increases and produces the tan, a possible indication of skin damage instead of the built in sunscreen.
Outdoor workers who cannot escape the intensity of UV rays are indeed prone to sun damaged skin. As for others, it would be advisable to refrain from sun exposure if there is a history of skin cancer in the family, the skin has moles or if suffering from other skin conditions. spells Miscarriage curse black magic.
It may seem like an exaggeration to wear a sunscreen every day no matter the high melanin in the skin but it is the sensible thing to do especially at these times when the ozone layer is deteriorating and the UV rays are its strongest.
Yes, melanin is the first line of defense, the built-in natural sunscreen, but the skin still needs an added layer of protection if the goal is to withstand early skin deterioration and enhanced beautiful complexion to last for long time.
