There are many ingredients not recommended during pregnancy and this is often purely cautious approach. Since testing on the skin of pregnant woman is not ethically permitted. Animal testing is now also banned in many countries. Many of these recommendations are based on anecdotal evidence, assumptions and animal studies.
Retinoids (Vitamin A)
One of the most popular active ingredients and is known for improving cell renewal, reducing wrinkles and reducing sun damage.
Previous scientific studies showed that high doses of Vitamin A taken orally can be harmful to unborn child. Even though there is no data that it is harmful when used on the skin during pregnancy, it is believed that caution is the best approach.
Commonly used Vitamin A ingredients:
Medical prescription only retinoids:
- retin-A/Renova/Tretinoin (medical prescription only)
- Tazorac/Tazoretene (medical prescription only)
- Retinoic acid (medical prescription only)
- retinol (most powerful non-prescription retinoid if in a stabilized form)
- retinyl palmitate
Salicylic acid/Beta hydroxy acid(BHA)
Salicylic acid is an exfoliating BHA and is excellent for unblocking pores in acne skin. It is in the same family as aspirin, an ingredient not recommended during pregnancy. Studies show that oral salicylic acid (aspirin) could cause birth defects and other pregnancy disorders. Although the amount of salicylic acid in your personal care product would be a small fraction of that found in aspirin, it is still good to be cautious.
AHAs (alpha hydroxy acids) such as lactic acid, malic acid, and mandelic acid are safe during pregnancy.
Soy is an estrogenic ingredient which can influence hormonal levels. While it is not dangerous to the unborn child, if you are prone to melasma (large dark pigmented patches on the face), soy products may worsen this condition during pregnancy.
Best to avoid:
- soy based skincare
- textured vegetable protein
