When you are trying to conceive, it is natural to focus on diet, supplements and lifestyle. You might start tracking your cycle, supporting your hormones, or eating more nourishing, fertility-friendly foods. But one area that is often overlooked is the everyday products we apply to our skin, hair and body.
We are usually careful about what we eat, but do we pay the same attention to what we put on our skin? The skin is permeable and many ingredients in personal care products are absorbed into the bloodstream. This becomes particularly relevant in the preconception phase, when you are working to create the healthiest possible internal environment for pregnancy.
The Problem with Petrochemicals
A large number of mainstream skincare, body care and cosmetic products are based on petrochemicals. These are substances derived from petroleum and crude oil. They may be used to preserve products, make them feel silky, create foam or fragrance, or simply to bulk them out because they are cheap and widely available.
Petrochemicals can burden the liver and disrupt the endocrine system. Some are known or suspected endocrine-disrupting chemicals, which means they can interfere with your hormones. This is especially important during the delicate process of trying to conceive, when hormonal balance is essential for ovulation, implantation and embryo development.
Petrochemical-Derived Ingredients to Avoid
Here are some common ingredients that may appear in your skincare products, all of which are derived from petrochemicals and can impact fertility:
- Paraffinum liquidum (mineral oil) Often used in moisturisers, this is a by-product of petroleum refining. It forms a film on the skin that may block pores and inhibit natural detoxification.
- Propylene glycol Common in creams and serums to help retain moisture, but it can irritate the skin and increase the penetration of other chemicals.
- Parabens (methylparaben, propylparaben, butylparaben) Used as preservatives, they mimic oestrogen in the body and are linked to hormonal disruption.
- Phthalates Often hidden under the word “fragrance” or “parfum,” these are plasticisers that can disrupt reproductive hormones and have been associated with reduced fertility.
- Sodium lauryl sulphate (SLS) and sodium laureth sulphate (SLES) These are foaming agents that can irritate the skin and are often contaminated with by-products of the petrochemical industry.
- Synthetic fragrance or parfum A single artificial fragrance can contain dozens of undisclosed chemicals, many of which are derived from crude oil and may disrupt hormones or sensitise the skin.
The Preconception Window is Precious
In the months leading up to conception, your body is preparing in subtle but powerful ways. Detoxification, hormonal signalling, egg and sperm quality, and the uterine environment are all influenced by your internal balance. Reducing your toxic load by avoiding petrochemicals is a simple but significant step that supports these natural processes.
Nourish Yourself Naturally
Choosing natural personal care products is an act of self-love. Look for certified organic or naturally formulated options that are free from petroleum-derived ingredients, artificial fragrance and synthetic preservatives.
Brands such as Neal’s Yard Remedies focus on high-quality botanical ingredients that support rather than suppress your body’s natural rhythms. Begin with the products you use most often, such as body lotion, deodorant and facial care. These small shifts create long-term benefits, not only for fertility but for overall well-being.
Conclusion
Trying to conceive is a time to simplify, nourish and connect more deeply with yourself. By making thoughtful changes to the products you use every day, you support your body in doing what it was made to do. Natural personal care is not about being perfect. It is about creating space for your hormones to settle, your liver to work freely, and your skin to breathe.
You deserve to feel safe, supported and ready. Let nature take care of you, so you can take care of what matters most.
