There is a lot of circumstantial evidence about the importance of whitening in Chinese aesthetics, such as “one white covers a hundred ugly”, such as “white rich beauty”, etc. Unfortunately, once pregnant, many people will have rough skin (a few will have good skin), acne, face, and stretch marks. There are pigmentation, often rashes, and stretch marks. The main reason for these skin changes is the rapid increase of progesterone, estrogen and androgen levels in the body after pregnancy. Most of these skin changes will disappear within a few months after delivery and gradually return to their pre-pregnancy state, but a few people are not so lucky. Darkening of the skin: Hyperpigmentation is caused by an increase in melanin during pregnancy, most of which disappears after delivery, but a few do not subside. Acne: Some people will get acne (pimples) after pregnancy. Acne is mainly related to the increase in androgen levels, so if you want to completely solve the problem of acne, you have to expect the hormone levels to drop after you have a baby. But there are still some ways to help alleviate the degree of acne, such as to insist on daily cleansing face with cleanser, in foreign countries, doctors will also recommend the appropriate use of some over-the-counter drugs containing benzene peroxide, formyl azelaic acid, salicylic acid, hydroxyacetic acid in the local application. Stretch marks: After pregnancy, many mothers-to-be will have stretch marks on their abdomen, buttocks, breasts and thighs. Most stretch marks will become less visible or fade after delivery, but some will never disappear. Is it useful to apply olive oil to prevent stretch marks? Does it help to use stretch mark prevention cosmetics? From the clinical results, it seems that the effect of stretch mark prevention cosmetics is not too good, but many mothers-to-be still try it, because it seems impossible not to let women apply it on their body, so they should try it if they have money, just in case it works. Rash: Some mothers-to-be will develop a skin rash after pregnancy, which may be accompanied by itching. If you go to a dermatologist, the TA will usually not prescribe you medication, but at most “glycolic lotion” to help relieve the symptoms. I’m pregnant and my skin is bad, can I wear makeup? Can I use beauty products? In principle, yes, it is best to wear light makeup and to choose natural beauty care products that are free of additives. A lot of beauty and skin care products are advertised with a lot of mystery, but not many of them seem to have reliable evidence-based medical evidence. Even so, these products continue to sell very expensive and sell like hotcakes. In terms of beauty and skin care products, it seems that women are generally not reasonable or scientific or evidence-based, as long as it feels right, even if there is only a 1% chance, she is still willing to spend a lot of money. In fact, women are not illogical, not evidence, not reasoning, but selective, choose their favorite to speak, choose to speak to their advantage. Most men do not understand this truth, even if they do, there is no way.
