Formaldehyde

Formaldehyde is a colorless gas often used in cosmetic products for its preservative qualities. It helps prevent the growth of bacteria and prolongs shelf life. It's commonly found in nail polish, hair straightening products and some hair dyes.

Potential Risks:

1. Teratogenic Effects: Clinical studies have shown that certain retinoids, particularly when taken orally, can have teratogenic effects – meaning they can cause birth defects in a developing fetus. These effects are most notable with isotretinoin, a potent oral retinoid.
2. Limited Research on Topical Retinoids: While topical retinoids (like retinol creams) have lower systemic absorption, there is still a lack of conclusive research on their safety during pregnancy. Out of caution, these are also generally advised against during pregnancy.

Research & Regulations:

• Due to its known risks, formaldehyde is heavily regulated in cosmetics. However, even at low levels, there are concerns about its safety, especially for pregnant individuals.

Professional Guidelines:

• Most health experts and regulatory bodies advise against the use of formaldehyde in cosmetics, particularly for pregnant women. They recommend opting for formaldehyde-free products to eliminate potential risks.

For those looking for safer cosmetic options:

• Formaldehyde-Free Nail Polish and Treatments: There are many brands that offer nail products free from formaldehyde and other harmful chemicals.
• Natural Hair Products: Opt for hair care products that use natural preservatives and are free from formaldehyde.
