Pregnant women should not use retinoids, which may induce fetal malformations and miscarriage. Oral retinoids are contraindicated in pregnant women because of the clear risk of fetal teratogenicity. Topical retinol and other related products also need to be converted to retinoic acid in the body to be effective, so there is a certain risk of inducing fetal malformation and miscarriage. In addition, retinol products are prone to skin irritation, resulting in skin allergies, redness, acne and other problems, and there are many restrictions on the use of medication during pregnancy, so retinol skin care products are not recommended for pregnant and breastfeeding women. Skin care during pregnancy is recommended to moisturize and protect the skin from the sun, and to avoid over-stimulating products. The use of retinol and other related products is not recommended during pregnancy and breastfeeding. If you are already using retinol, it is recommended that you discontinue its use and follow up with prenatal checkups and evaluations.
