20 years old (female), freckles began to appear at the age of 13. How can I dilute the freckles on my face? Let's talk about what we have been through.

The causes of freckles are: 1, living habits. Bad habits such as stress, partial eclipse and lack of sleep can also produce melanin.

Increase. 2, some diseases Many diseases will change the normal skin color, making it black or even long spots. Among them, the most common diseases are endocrine system diseases, chronic wasting diseases and malnutrition diseases. 3. Ultraviolet rays stimulate melanin in the skin and induce skin lesions such as freckles. Even on cloudy days, "ultraviolet rays" are still very strong. Ultraviolet rays can cause skin blackening, aging and wrinkles. 4, some photosensitive foods Some foods are also the bane of skin blackening, and foods rich in metal elements such as copper, iron and zinc have this drawback. 5. Causes of secretion. Endocrine disorder is also an important cause of female pigmentation. Changes in sex hormone levels during menstruation and pregnancy will affect the production of melanin. 6. Genetic reasons. Autosomal inheritance is the main cause of freckles. Most of them start from children around the age of 5, mostly women, emphasizing spring and summer over autumn and winter. Light brown to yellowish brown spots from the tip of a needle to the size of a grain of rice are symmetrically distributed on the face (especially the nose).

Methods of preventing freckles

1, do a good job of sun protection, spots are most afraid of sun exposure. Sun exposure or excessive exposure to X-rays and ultraviolet rays will promote pigmentation and aggravate it. Even fluorescent lamps used for indoor lighting aggravate the color spots due to the excitation of ultraviolet rays, so it can be considered that color spots are a physical and destructive skin disease. Sunlight can increase the activity of melanin, which leads to the increase of melanin content in the basal layer of epidermis and the formation of pigmentation. In summer, sunshine is abundant, spots are active frequently, the number of spots increases, the color deepens and the harm becomes greater; In winter, the sunshine is less, the number of spots is reduced, the color change is lighter, and the damage is reduced. It can be seen that sun exposure is a necessary factor for pigmentation, so patients should try to avoid long-term sun exposure, especially in summer.

2. Prevent all kinds of ionizing radiation, including all kinds of glass shell display screens, all kinds of fluorescent lamps, X-ray machines, ultraviolet irradiators, etc. These bad stimuli will have consequences similar to strong sunlight, even greater than the damage caused by sunlight, and the result is aggravated pigmentation.

3, careful use of all kinds of trauma treatment, including freezing, laser, ions, strong acid and alkali and other corrosive substances, otherwise it is easy to cause disfigurement!

4. Use cosmetics and skin care products with caution. It is forbidden to use "quick-acting freckle cream" containing harmful substances such as hormones, lead and mercury, because there are too many side effects, which may produce hundreds of side effects, which will seriously lead to disfigurement!

5. Avoid irritating food. Irritant foods can age the skin. Especially coffee, cola, strong tea, cigarettes, wine, etc. The more you eat, the faster you age, causing melanin molecules to float on the skin surface, making dark spots bigger and darker.

6. Drink plenty of water and eat more fruits and vegetables, such as tomatoes, cucumbers, strawberries and peaches.

In life, we will also hear about skin care products that can remove spots. Although these skin care products have some effects, they all have chemical components, and long-term use will have side effects.

Medical laser freckle can be removed: laser freckle uses the principle of selective photolysis of laser. With the help of high energy generated by laser, these pigments are crushed, and the pigment fragments are eliminated from the body with various cycles of the human body, thus achieving the purpose of treatment.

If freckles appear and persist for a long time, it is suggested to go to a regular big hospital for laser freckle treatment and Meilai laser freckle treatment, use VISIA skin detector to analyze the freckle characteristics of beauty seekers and treat them separately, and use Meilai's original Chinese medicine secret recipe combined with laser treatment to treat them from the outside to the inside, so as to cut off the root causes of freckles and prevent rebound. Meilai laser freckle has no harm and does not need a recovery period. The effect is remarkable. After treatment, sunscreen and moisturizing can make the skin look white and moist.
