Should I be concerned about using cosmetics while trying to conceive or during pregnancy?

It is natural for this topic to cause you concern, but the short answer is that "awareness" and switching to safer options are better than excessive worry. While some cosmetics contain chemicals that may interfere with the body's hormonal balance, the primary goal is to minimize unnecessary exposure to these substances as much as possible rather than worrying about their limited use. It is always recommended to make conscious, gradual choices to protect your reproductive health and the health of the fetus during these sensitive stages.

What are endocrine disruptors?

The human body has a delicate endocrine system that controls vital processes such as growth, fertility, and reproduction. Some chemicals found in daily products are known as "endocrine disruptors"; these are substances that can mimic, block, or interfere with natural hormone signaling in the body. Research indicates that exposure to even low levels of these substances may lead to noticeable biological and developmental effects [1].

These substances are found in many cosmetics and personal care products, such as phthalates, which are used as plasticizers in nail polish, hair sprays, skin care products, and shampoo. Since these substances are absorbed through the skin, reducing reliance on products that contain long and complex lists of chemicals is a logical preventive measure.

Potential impact on fertility and pregnancy

Chemical, physical, and biological substances are among the risks that may affect reproductive health. For men, some substances may contribute to changes in sperm quality or motility. For women, hormonal interference can lead to menstrual cycle disorders, which affects fertility [2].

As for during pregnancy, the timing of exposure to hazardous materials plays a crucial role in the magnitude of the risks. In the first trimester, exposure to harmful substances may be associated with increased chances of miscarriage or congenital anomalies, whereas in later stages, it may affect fetal growth or contribute to conditions such as preterm birth [2]. For example, studies have indicated an association between certain levels of phthalates in the body and reduced gestational age at birth and an increased risk of preterm birth [1]. It is important to understand that the risks depend on the type of substance, the amount of exposure, and the frequency of use, not just the use of the product itself.

Practical steps to reduce risks

You can reduce the likelihood of exposure to these substances by adopting safer consumer habits:

• Read labels: Look for products that state they are "phthalate-free."
• Simplify: Reduce the number of personal care products you use daily, which reduces the potential for cumulative exposure to different chemicals.
• Personal hygiene: Ensuring you wash your hands thoroughly before eating reduces the chances of transferring topical chemicals from the skin to the body [2].
• Continuous knowledge: For more details on how to avoid chemical risks in your environment, you can read our article on Reproductive Hazards: Environmental and Chemical Factors Affecting Fertility and Pregnancy (Arabic).

If you have specific concerns about a product you use regularly, or if you are facing challenges related to fertility, it is always recommended to consult a specialist doctor to provide advice tailored to your health status and medical history, helping you make the best decisions for you and your baby.
