Melanin is an element in the human body. It has a great impact on the human body. Mainly, once melanin is deposited in the skin, it will form various spots, which are particularly ugly. Especially girls who love beauty hope that their skin can be smoother and do not want any blemishes. If you want to prevent spots, you must inhibit the deposition of melanin. So, what is the easiest way to get rid of melanin? What is the true identity of melanin? Melanin is actually a protein that exists in everyone's body. They exist among the cells in the basal layer of the skin. At this time, they are not true melanin, but something called "melanin protocell", also called "pigment mother cell". Pigment stem cells secrete melanin. When ultraviolet rays (B waves, A waves) irradiate the skin (B waves, namely UVB, act on the basal layer of the skin, while A waves are more powerful and act on the dermis of the skin), the skin will be in a state of "self-protection", stimulating melanin through ultraviolet rays and activating the activity of tyrosinase to protect our skin cells. Tyrosinase reacts with tyrosine in the blood to produce a substance called "DOPA". DOPA is actually the precursor of melanin, which is oxidized by tyrosine to release melanin. Melanin moves through layers of cell metabolism and reaches the epidermis of the skin to form freckles, sun spots, dark spots, etc. It seems that melanin is a substance produced by the skin to avoid damage from ultraviolet rays. From a certain perspective, it is a "good guy", but its image is a bit "bad". If the body's ability to synthesize melanin decreases, the skin will become sensitive. This is the reason why the incidence of skin cancer in many European countries is higher than that of black Africans. So, melanin can protect our cells. How to inhibit melanin But due to different aesthetic views, we need to appropriately inhibit melanin production. After all, skin whitening is a never-fading fashion topic for us Asians, and the fact that major companies are vigorously developing skin whitening products is enough to prove this. Of course, properly inhibiting melanin will not cause harm to health. So how can we whiten the skin and make it healthy at the same time? Scientific views on sun protection and diet Don’t forget to use sunscreen while doing whitening care. During whitening care, the melanin that has already been produced can be slowly eliminated, while sunscreen can help the skin inhibit the production of new melanin. Good sunscreen products can protect the skin's basal layer and dermis from damage by ultraviolet rays, do not stimulate the activity of tyrosinase, and inhibit the production of melanin. |
