1, salicylic acid
Salicylic acid can treat many skin problems, such as acne, skin cleansing, relieving skin inflammation, anti-aging, etc., but pregnant women should avoid using skin care products containing salicylic acid, because a large number of skin care products containing salicylic acid can easily lead to fetal malformation and various pregnancy complications, which is not good for pregnant women and fetuses.
2. aloe oil
Aloe vera is a natural beauty product, but it can replenish water and moisturize, and it can also achieve a calming and soothing effect. But for pregnant women, whether it is aloe vera for external use or aloe vera for oral use, it will cause great harm to pregnant women. If aloe vera is used for a long time, it will make pregnant women's pelvic organs congested, promote uterine movement, cause abdominal pain or bleeding, and even lead to abortion in severe cases.
3. Vitamin A component
Vitamin A in skin care products mainly includes vitamin A acid, vitamin A lipid and vitamin A aldehyde. Both vitamin A fat and vitamin A aldehyde can be converted into vitamin A acid in the skin, and vitamin A acid will increase the teratogenic rate of the fetus, so pregnant women should ban the use of skin care products containing vitamin A.
4. Steroid hormones
Pregnant women should also put an end to the use of skin care products containing steroid hormones, which will make the placenta of pregnant women much smaller than normal, and the baby is prone to have low birth weight at birth, which has a serious impact on the physical and mental health of pregnant women and fetuses.
5. Peroxide is stupid
In skin care products, peroxide is mainly used to treat acne, but during pregnancy, pregnant women must stop using skin care products containing peroxide, which is very functional and will have a certain health impact on pregnant women and fetuses.
6. Heavy metals such as lead and mercury
When pregnant women use skin care products, they must not contain lead and mercury or other heavy metals, because lead and mercury are both heavy metals, which will not only have a certain impact on pregnant women's own health and skin, but also be easily absorbed by skin and blood and passed on to babies, leading to developmental retardation or fetal malformation.
aha
AHA is mainly fruit acid, which exists in exfoliating skin care products. Because these skin care products and skin care products contain preservatives and additives, some of them will affect the growth and development of the fetus, so pregnant women should also ban skin care products containing such substances.
8. How do pregnant women choose skin care products?
(1) Moisturize and moisten
During pregnancy, pregnant women's skin will become more sensitive than usual, and daily skin care products have many functions, such as whitening, wrinkle removal and anti-aging. However, for pregnant women, the more functions skin care products have, the more complicated the ingredients are, but not all the ingredients are suitable for pregnant women. Some ingredients are safe, but not suitable for pregnant women, so pregnant women should choose skin care products with moisturizing as the basic function.
(2) Simple components
Pregnant women should pay attention to ingredients when choosing skin care products. Preservatives, pigments, aromatic compounds and other ingredients commonly found in skin care products must not be touched during pregnancy. They are also the three major substances that cause skin allergies. The more complex the perfume composition, the heavier the irritation, and the more likely it is to cause skin allergies and photosensitive reactions. Therefore, it is best for pregnant women to choose skin care products with simple ingredients and plant extracts, which are non-irritating and have no effect on pregnant women and fetuses.
(3) Only for pregnant women
Pregnant women should choose special skin care products for pregnant women when using skin care products. This kind of skin care products are different from ordinary skin care products in raw material composition, which requires higher testing requirements and is more suitable for pregnant women's skin care. Pregnant women's articles are divided into pregnant women's articles and pregnant women's articles. When pregnant women choose, they must choose special products for pregnant women, which have higher safety performance.
9. Problems that easily occur during pregnancy
(1) Acne, oily and sweaty.
Acne is not a patent for teenagers. After pregnancy, some pregnant mothers will have acne on their faces, or make the original acne worse. In the early stage of pregnancy, in order to make the fetus grow steadily, the secretion of lutein in the body will increase, which will indirectly make the skin secrete more oil and make pregnant mothers prone to acne.
Oil sweating is not only related to the hot summer, but also the faster metabolism during pregnancy. Some mothers have exuberant sebaceous glands and their faces become greasy and rough due to the influence of hormones. In addition, due to the increase of estrogen secretion, the adrenal cortex function is in a state of hyperfunction, and the skin blood flow increases, which is easy to cause sweating.
(2) Pigment precipitation
This is what most mothers will encounter. Due to the increased secretion of estrogen and lutein in pregnant mothers, about 50-70% of pregnant mothers will have dark brown liver spots on their cheekbones and cheeks in the second trimester, and the colors of women's areola, armpits and private parts will also become darker.
(3) Stretch marks
In addition to the influence of hormones, rapid weight gain is also one of the main reasons for stretch marks that people love and hate. Excessive stretching of the skin leads to the rupture of collagen fiber tissue and the appearance of stretch marks. The stretch marks formed at the beginning are pink, which will become silvery white stripes over time and become permanent lines that are difficult to disappear.
(4) vascular nevus and erythema
In fact, it is not as terrible as imagined, but the increase of female hormones has changed blood vessels. When pregnant for 2 ~ 5 months, small spider-like vascular nevus will appear on the face, neck, upper chest and arms, and erythema will appear on the palm.
