01 Factors that cause birth defects
(1) The exposure time window: The most sensitive stage of the organs of human embryo is the 5-11 weeks of menopause. In this sensitive stage, it is exposed to adverse factors, which is most likely to cause birth defects.The embryos are either formed at other times, or the organizational organs have been differentiated, and the possibility of exposure to adverse factors that cause birth defects is relatively small.
(2) Types of chemicals exposed: Different chemicals have different terators, which will act on different tissue organs targets, so it cannot be generalized.
(3) Cumulative doses of exposure: Generally speaking, a small amount, general exposure will not increase or increase the risk of birth defects slightly. The adverse exposure that truly increases the risk of birth defect is professional exposure, such as the staff of the chemical plant.

After being absorbed by the skin, it will be converted into vitamin A.Victoria -A acid oral adaptation may cause fetal birth defects.External use of skin care products containing Vitamin A can not be determined on the fetus. For safety reasons, it is recommended not to use skin care products containing vitamin A ingredients.
2. salicylic acid
Salmonic acid can remove aging keratin accumulation, promote skin metabolism, and shrink pores to remove acne acne.However, salicylic acid has strong permeability. Excessive removal of the stratum corneum will make the skin defense difference. It is more likely to cause symptoms such as erythema, itching, and tingling.In addition, high concentration of salicylic acid still has teratogenic effects on the fetus.

Pregnant women exposed to a certain concentration of phthalate can cause premature birth, abnormal embryonic development or fetal weight when they are born.Light.
5. Dispenone ketone
Benzhenone chemicals mainly exist in sunscreen products as a chemical sunscreen.However, if diophenone is touched during pregnancy, it may cause expectant mothers to be allergic to light, and it may also affect the growth and development of the fetus.
