These impressive, topical anti-wrinkle agents, which are vitamers of vitamin A, are widely used in skin care products of all sorts, however, they are not recommended for use during pregnancy. In fact, pregnant women should avoid anything with vitamin A derivatives, such as Retin A (tretinoin), retinol or retinoic acid, according to Anna Guanche, MD, dermatologist and founder of the Bella Skin Institute, as studies have shown it may be harmful to the developing fetus. "This also includes the oral form, isotretinoin (formally known as Accutane), which is known to cause birth defects in pregnant women," she adds.
Beta hydroxy acids, such as salicylic acid and alpha hydroxy acids, are commonly found in topical preparations for acne and anti-aging. They should not be used during pregnancy, according to Brauer since salicylic acid in its oral form has been shown to cause potential birth defects and pregnancy complications. "While using low dose salicylic acid preparations sparingly is likely not harmful to a pregnancy, most doctors recommend avoiding it all together since its use is elective and for cosmetic reason," she adds.
Yep — you can expect that you'll probably have to switch out your regular sunscreen once you're pregnant. "Prolonged, direct sun exposure should be avoided in pregnancy for both health and cosmetic reasons, but if you must be out in the sun it is extremely important to wear sunscreen," Brauer says. "It's recommended that pregnant woman, as well as infants and kids, stick with a physical sunscreen, such as titanium dioxide or zinc oxide, as opposed to chemical sunscreens, which can be absorbed into the bloodstream and has been linked to potential pregnancy complications and birth defects."
If you frequently whiten your teeth, you'll have to postpone your next session until after baby's due date. "There have not been enough reliable studies to show that peroxide, the main ingredient in whitening kits, is safe during pregnancy," explains Ross. You may also want to postpone your regular teeth cleaning, since pregnant women experience increased blood flow to the mouth and gums which can cause increased sensitivity and bleeding. "Daily teeth cleaning and flossing is best for mouth and teeth hygiene during pregnancy," Ross says. "Cosmetic dental procedures should wait until after pregnancy."
Most minimally invasive skin procedures, such as botox, dermal fillers, laser facials or peels, which are often used to prevent wrinkles in the face, should be avoided during pregnancy, Ross says. "There is not enough research done on these potential harmful cosmetic products."
