cause
The formation of stretch marks is mainly influenced by pregnancy hormones. The swelling of the abdomen causes the elastic fibers and collagen fibers of the skin to be damaged or broken to varying degrees due to external forces, and the skin becomes thinner and thinner, and some pink or purple wavy patterns with different widths appear on the abdominal wall skin.
Time prone to stretch marks
The most prone time to stretch marks is one month before delivery. This may be because the fetal weight will increase about 1 kg in the last month, and the stomach will increase rapidly to produce stretch marks. In the second trimester of pregnancy, there will also be sudden weight gain in a short period of time, but most of them are near the expected date of delivery.
The color of stretch marks
When the local skin is stretched and thinned, the walls of capillaries and veins in the dermis will also expand and become thinner, exposing the color of blood, and the skin stripes will be purple or pink. After delivery, the broken elastic fibers can be slowly repaired, the walls of capillaries and veins in the dermis will gradually thicken, and the color of skin stripes will gradually fade to white or silvery white, but it can not completely return to the skin state without cracks before pregnancy.
Prevention of stretch marks
The prevention of stretch marks should start from the first trimester, maintain a proper weight to avoid excessive weight gain, eat more foods rich in vitamins E, C and A, such as green leafy vegetables, fruits and nuts, keep your skin moist, drink plenty of water, and apply skin care products containing vitamins E, C and A such as lotion and oil to avoid excessive exercise, tight clothes and excessive massage.
