1. Retinoids (Retinol, Retinyl Palmitate, Retin-A): As mentioned earlier, excessive vitamin A derivatives, commonly found in anti-aging creams and acne treatments, should be avoided during pregnancy due to their potential to cause birth defects.
2. Salicylic Acid: While salicylic acid is a common ingredient in acne-fighting products, high doses in oral form have been associated with birth defects. It’s advisable to consult a healthcare provider before using products containing salicylic acid.
3. Formaldehyde and Formaldehyde-Releasing Preservatives: Found in some nail polishes and hair straightening treatments, formaldehyde is a known carcinogen. Additionally, some preservatives release small amounts of formaldehyde, posing potential risks.
