How are freckles formed?

The problem of freckles bothers many people, and we all know that some people have used various freckle removal products but have not achieved the desired results. In fact, the key lies in whether you understand the causes of freckles, prevent them from the root cause, and take corresponding measures.

1. Genetic factors: However, it is not necessarily inherited from your parents, it may be inherited from several generations. Generally speaking, freckles mostly appear on the face with fair skin.

2. Sun exposure: On the one hand, the ultraviolet rays in the sun stimulate the frequent activity of the pigment cells under the skin and produce a large amount of melanin; on the other hand, it damages the normal metabolic function of skin cells, making it impossible for melanin to be excreted smoothly and remain on the skin, or even deposited in the dermis. Therefore, excessive sun exposure will aggravate and deepen freckles, but in winter the freckles will gradually fade. Freckles are formed due to the deposition of melanin in the body. When the skin is exposed to ultraviolet rays, the blood becomes acidic and produces acidifying enzyme (tyrosinase), which causes the melanin stored in the surface cells to start moving and float on the surface of the skin, helping to prevent the body from absorbing excessive ultraviolet rays to resist external heat and form freckles.

3. Endocrine reasons: Endocrine disorders are also an important factor in the formation of freckles in women. Changes in sex hormone levels in women during menstruation or pregnancy will affect the formation of freckles. In addition, endocrine disorders can also lead to emotional instability, indirectly causing the formation of freckles.

4. Lifestyle habits: The formation of freckles is closely related to lifestyle habits. Bad habits such as stress, picky eating, and lack of sleep will lead to an increase in melanin, which in turn leads to the appearance of freckles. Therefore, people with unstable sleep schedules have poor skin metabolism rate, which leads to the appearance of freckles. In addition, the metabolism of the skin's stratum corneum is also closely related to the formation of freckles. If the metabolism of the stratum corneum is good and active, and the melanocytes undergo division, they will be brought out of the epidermis in time, becoming dirt and separating from the skin. Otherwise, the chance of developing spots will increase. Through the above introduction, female friends should have a general understanding of the causes of freckles. Pay more attention to your daily routine to prevent the appearance of freckles. We must take precautions before it happens.
