Introduction
Chemical sunscreens have long been a staple in skincare, offering protection against the harmful effects of UV radiation. However, their use during pregnancy has raised concerns about potential risks. In this article, we will explore what chemical sunscreens are, their purposes in skincare products, and why there are concerns about their use during pregnancy. We will also provide guidance for pregnant women on best practices and alternatives for sun protection.
What Are Chemical Sunscreens and Their Purpose?
Chemical sunscreens, also known as organic or synthetic sunscreens, contain active ingredients such as avobenzone, oxybenzone, octisalate, octocrylene, and homosalate. These ingredients work by absorbing UV radiation and converting it into heat, which is then released from the skin. Their primary purposes in skincare products include:
- UV Protection: Chemical sunscreens protect the skin from the harmful effects of UVB (burning) and UVA (aging) rays, reducing the risk of sunburn and premature aging.
- Broad Spectrum Coverage: Many chemical sunscreens offer broad-spectrum protection, safeguarding the skin against both UVA and UVB radiation.
- Lightweight Formulas: Chemical sunscreens are often preferred for their lightweight and non-greasy consistency, making them suitable for daily use.
Concerns About Using Chemical Sunscreens During Pregnancy
While the use of chemical sunscreens is generally considered safe for most people, including pregnant women, some concerns have been raised, particularly about specific ingredients:
- Oxybenzone: Oxybenzone is an ingredient found in some chemical sunscreens. Concerns have been raised about its potential to be absorbed through the skin and disrupt hormones.
- Octinoxate: Octinoxate is another common chemical sunscreen ingredient. It has been associated with hormone disruption as well, which may be a concern during pregnancy.
Sources of Concern
- American Academy of Dermatology (AAD): AAD notes that the potential risk of sunscreen ingredients being absorbed into the body, including oxybenzone and octinoxate, is still being studied, and while the risks appear to be minimal, it may be advisable for pregnant women to exercise caution.

- U.S. Food and Drug Administration (FDA): The FDA is evaluating the safety and efficacy of sunscreen ingredients, including the potential for systemic absorption, and is continuously updating guidelines.
- Environmental Working Group (EWG): EWG highlights concerns regarding certain chemical sunscreen ingredients and their potential impact on hormones and the environment. (source)
Best Practices for Pregnant Women:
a. Consult a Healthcare Provider: Before using any sunscreen product during pregnancy, consult with a healthcare provider, such as an obstetrician or dermatologist, to discuss your specific needs and any potential concerns.
b. Physical Sunscreens: Consider using physical sunscreens that contain active ingredients like zinc oxide or titanium dioxide. These ingredients are generally considered safe during pregnancy and offer effective UV protection.
c. Broad Brimmed Hats and Protective Clothing: In addition to sunscreen, protect your skin from UV radiation by wearing wide-brimmed hats and clothing that covers your arms and legs.
d. Seek Shade: When possible, seek shade to reduce sun exposure during peak hours when UV radiation is strongest.
Conclusion
While chemical sunscreens are widely used and generally considered safe, concerns about specific ingredients have led to caution during pregnancy. Pregnant women should consult healthcare providers and consider using physical sunscreens or alternative methods of sun protection to ensure the safety of both themselves and their developing baby. Sun protection is vital, but it’s essential to make informed choices, especially during this important phase of life.
