Musk can cause miscarriage, especially natural musk. Natural musk is mainly from musk deer, a rare animal, but in recent years the country has banned the hunting and killing of musk deer, so most of the musk on the market is synthetic, synthetic musk contains chemicals, such as chemical preservatives, additives and chemical fragrances, and irritating odor. If a pregnant woman is under the stimulation of this irritating smell for a long time, it may lead to miscarriage or even premature birth. Therefore, it is recommended that pregnant women should not use products containing musk, like perfume, body wash, mosquitoes and soap, and should use more skin care products for pregnant women. It is recommended that pregnant women should stay away from substances with irritating odors to avoid bad effects on the fetal baby.
