If you use skin care products containing salicylic acid in early pregnancy, you do not need to worry too much if you do not feel unwell for a day, but you can go to the hospital dermatology and obstetrics and gynecology department for examination and avoid using them again in the future. Salicylic acid skincare products are acidic and an anti-inflammatory drug, and their use in large quantities during pregnancy can damage the stratum corneum, leading to a decrease in skin defenses and causing skin erythema, itching, tingling and allergies. In severe cases, it can cause systemic symptoms, such as tinnitus, dizziness, tiredness, nausea and many other conditions, which pose a threat to the health of pregnant women during pregnancy, so in principle, skin care products containing salicylic acid should not be used during pregnancy. It is best to use gentle, non-irritating skin care products during pregnancy. Skin is very sensitive during pregnancy, so use a gentle, non-irritating cleanser every time you wash your face. If you have skin acne during pregnancy, choose natural plant-based skin care products to moisturize your skin while you clean it well. You can take folic acid supplements on a daily basis, increase nutrition, eat more vegetables and fruits, and have regular prenatal checkups.
