Why does the skin get tanned easily?

The hot summer is here, and sometimes even layers of sunscreen can't prevent the painful trouble of tanning. Especially when you apply sunscreen and wear a sun hat or umbrella, you still feel like your whole body is tanned all day long. This makes many friends who love beauty very distressed. So, why is the skin easily tanned? Many friends who love beauty want to understand this issue clearly.

The three main culprits that cause skin darkening and pigmentation are: UV rays, toxin accumulation and cell irritation. The UV rays in the sun are just one of the reasons why we darken. As we all know, the main cause of skin darkening is melanin. However, few people care about the melanocytes in the epidermis that are responsible for secreting melanin. It is distributed in large quantities in the epidermis of everyone's skin. Under certain circumstances, it is activated and releases melanin.

UV rays

It activates tyrosinase in melanocytes, producing a series of reactions with tyrosine in the blood to generate a substance called "DOPA", which is then converted into melanin.

Toxins in the skin

"Oxygen" is vital to the skin, but it can also have negative effects: it can produce an oxidative reaction with tyrosinase and turn into toxins in the skin - free radicals, which in turn can lead to the oxidation of tyrosine, generate "DOPA", and release melanin. Pollution, radiation and smoke in daily life will also aggravate the oxidation process.

Cells are stimulated

Various external threats in urban life, such as pollution and sunlight, can cause micro-inflammation of skin cells. Skin cells naturally secrete a substance called arachidonic acid to calm this inflammation. This arachidonic acid substance activates tyrosinase to a certain extent and promotes the production of melanin.

The above content is a detailed introduction to some of the reasons why the skin is easily tanned. I believe that now everyone should have a deeper understanding and knowledge about why the skin is easily tanned. I hope that the above introduction can help more beauty-loving friends. Here, experts remind you that once the skin is tanned, relevant skin care measures should be taken in time to avoid skin damage.
