What is the reason for the spots on the face of a 40-year-old woman

What causes spots on the face of a 40-year-old woman? In fact, many people are confused when they see spots on their faces. They don’t know what to do to remove the spots on their faces. So today, the editor will accompany you to understand: Why do women get spots on their faces and what are the solutions for dark spots?

The first reason for spots on women's faces: ultraviolet light

In the process of pigment conversion, the most direct influence comes from the ultraviolet light in the sun, which can activate tyrosinase in melanocytes, produce a series of reactions with tyrosinase in the blood, and convert it into a substance called "DOPA", which converts pigment.

The second reason for spots on women’s faces: accumulation of endotoxins

The toxins in the skin can activate the specificity of cells, and at the same time cause a redox reaction with tyrosinase, converting into "DOPA" and releasing pigment. However, the pollution, radiation and dust that we have to deal with in our daily lives will aggravate the oxidation process and make the skin color dull and uneven.

The third reason for spots on women’s faces: body cells are stimulated

Environmental pollution, the sun, and ingredients are all factors that can cause inflammation of skin cells. In order to repair inflammation, skin cells will naturally react and secrete a tetraenoic acid substance, which in a certain extent activates tyrosinase to promote the conversion of pigments.

The fourth reason for women to have spots on their faces: work pressure

When people are under work stress, they metabolize adrenaline to prepare for coping with work stress. If you are under stress for a long time, the metabolic balance of the body will be disrupted, the supply of nutrients needed by the skin will slow down, and the melanocytes will become very active, leading to pigmentation.

The fifth reason for spots on women’s faces: slow basal metabolism

Spots may also appear when the liver's basal metabolic function is abnormal or the ovaries are reduced. Due to poor basal metabolism or endocrine imbalance, the human body is in a more sensitive state, which aggravates the melanin problem. Constipation can cause acne, which is actually caused by endocrine imbalance leading to allergic constitution. Under abnormal human body conditions, direct exposure to ultraviolet light will also accelerate the formation of spots.
