Parabens in Skincare: What They Are & Why We Formulate Without Them
Parabens are effective preservatives, but they are also chemicals with documented estrogenic activity. Research has shown that several commonly used parabens can interact with estrogen receptors, be absorbed through the skin and be detected throughout the human body. That is exactly why Natural Escapes chooses to formulate without them.
We do not believe a preservative has to be controversial to be effective. Water-based skincare absolutely needs proper preservation, so instead of leaving products under-protected, we use an alternative preservation system that better fits our ingredient standards and our plant-forward formulation philosophy.

Quick Takeaways
- Parabens are preservatives used to control bacteria, yeast and mold in cosmetics.
- Several parabens have demonstrated estrogenic activity in laboratory and animal research by interacting with estrogen receptors.
- Parabens can be absorbed through the skin and have been widely detected in human urine and blood.
- Repeated and combined exposure remains an active area of research. People are exposed to parabens from multiple personal-care products, foods and pharmaceuticals, not one isolated source.
- Natural Escapes chooses a different preservation system. We use benzyl alcohol and dehydroacetic acid in many of our water-based formulas because it gives us effective preservation while aligning better with recognized natural and organic cosmetic standards.
What Are Parabens?
Parabens are a family of preservatives used to keep cosmetics, personal-care products, foods and pharmaceuticals from becoming contaminated with bacteria, yeast and mold.
Common parabens include:
- Methylparaben
- Propylparaben
- Butylparaben
- Ethylparaben
They became popular because they are effective, inexpensive and easy to formulate with. But effectiveness is only one part of ingredient selection. At Natural Escapes, we also care about the larger research picture and whether an ingredient fits the standards we want for our products.
Do Parabens Mimic Estrogen?
Yes. Several commonly used parabens have demonstrated weak estrogenic activity. Research has shown that methylparaben, ethylparaben, propylparaben and butylparaben can interact with estrogen receptors, with activity varying by the specific paraben.
One of the landmark studies found that several parabens were able to activate estrogen-responsive systems, with butylparaben showing the strongest activity among those tested. View the estrogenic paraben study on PubMed.
Later reviews have continued to document estrogen-receptor activity and other endocrine-related effects. A 2018 review specifically summarized parabens as chemicals capable of influencing endocrine signaling, while a 2026 review again concluded that methylparaben and propylparaben show weak estrogenic activity and that repeated and cumulative exposure deserves further study. Read the endocrine-system review and see the 2026 review on absorption into the body and estrogenic potential.
Paraben estrogenic activity is weaker than the body's natural estrogen, but the biological activity is documented. Combined with repeated everyday exposure, that is enough reason for us to choose an effective alternative.
Are Parabens Absorbed Into the Body?
Yes. Human exposure is well documented. Research has shown that parabens from topical products can penetrate the skin and be measured inside the body.
A review of dermal absorption and human exposure found that intact paraben esters can cross human skin and be detected inside the body. View the dermal absorption review on PubMed.
More recently, a controlled 2025 study asked adults to use a lotion containing known amounts of parabens. Paraben levels increased in urine during the lotion-use period, directly connecting personal-care product use with internal exposure. View the human lotion-exposure study on PubMed.
A massive 2025 global analysis measuring paraben levels in people reviewed data from 203 publications across 29 countries, including more than 370,000 urine measurements and nearly 20,000 blood measurements. The study confirmed widespread human exposure to multiple parabens. View the global human-exposure study on PubMed.
Why Long-Term & Cumulative Exposure Matters
The question is not whether one tiny exposure instantly causes harm. The more useful question is what happens when people are exposed repeatedly through lotions, makeup, hair products, medications, foods and other everyday sources.
A review focused specifically on parabens and estrogen receptors pointed out an important research gap: most traditional safety evaluations look at individual parabens, while real-world exposure often involves multiple parabens from multiple products. The review concluded that cumulative risk from those combined exposures could not be fully assessed from the available data. Read the cumulative-exposure review on PubMed.
Human reproductive research is also continuing to evolve. A 2024 review of female reproductive health found that the overall evidence is still developing, but reported significant findings in some human population and animal studies involving fertility, pregnancy, hormone signaling and reproductive development. View the 2024 reproductive-health review.
In a prospective study of 884 couples, higher paraben exposure in female partners was associated with a lower chance of becoming pregnant. This type of observational study shows an association rather than proving cause, but it adds to the reasons researchers continue to examine repeated paraben exposure. View the fertility study on PubMed.
Because parabens have raised legitimate concerns around estrogenic activity, repeated exposure and cumulative exposure, we prefer not to use them when effective alternatives are available.
For us, it is a simple formulation decision: when an ingredient raises meaningful health concerns and we can achieve excellent product safety and performance with an alternative that better fits our standards, we choose the alternative.
Why Natural Escapes Formulates Without Parabens
Our ingredient philosophy has always been about making purposeful choices, not simply following what is easiest or cheapest to formulate with.
We choose paraben-free preservation because:
- Parabens have documented estrogenic activity.
- Human exposure from personal-care products is measurable.
- Repeated and combined exposure remains under active study.
- Effective alternative preservatives are available.
- Our customers expect thoughtful, ingredient-conscious formulas.
That is enough reason for us to formulate differently.
Paraben-Free Does Not Mean Preservative-Free
A safe water-based lotion, shampoo, conditioner or body wash still needs proper preservation. Aloe juice, water and botanical ingredients create an environment where bacteria, yeast and mold can grow if the formula is not adequately protected.
We are not interested in making a product sound cleaner at the expense of microbiological safety. Our goal is to protect the finished product effectively while choosing a preservation system that better matches the rest of the formula.
What We Use Instead of Parabens
Many Natural Escapes water-based formulas use a preservative system based on benzyl alcohol and dehydroacetic acid.
This combination is accepted for use under the COSMOS standard for natural and organic cosmetics. COSMOS specifically lists benzyl alcohol and dehydroacetic acid among the preservatives permitted in COSMOS NATURAL and COSMOS ORGANIC formulations. Raw materials preserved with this combination also appear in the COSMOS database under certification bodies such as ECOCERT Greenlife.
That is a much better fit for the kind of products we want to make. It gives us the preservation we need without relying on parabens, while aligning with a recognized natural and organic cosmetic framework.
You may see this preservative system listed on our ingredient labels as benzyl alcohol and dehydroacetic acid or as part of an eco-certified preservative blend, depending on the specific formula.
How to Spot Parabens on an Ingredient List
If you want to avoid parabens, ingredient labels make it fairly easy. Look for names ending in “paraben.”
- Methylparaben
- Propylparaben
- Butylparaben
- Ethylparaben

Frequently Asked Questions
Parabens are preservatives used to protect cosmetics from bacteria, yeast and mold. Common examples include methylparaben, propylparaben, butylparaben and ethylparaben.
Several parabens have demonstrated weak estrogenic activity and can interact with estrogen receptors. Their activity is weaker than the body's natural estrogen, but their endocrine activity is well documented and remains an active area of research.
Yes. Human studies and human monitoring studies have shown that parabens from personal-care products can be absorbed and detected in urine and blood.
We avoid parabens because they have documented estrogenic activity, human exposure is widespread, cumulative exposure is still being studied, and effective alternative preservation systems are available that better fit our ingredient philosophy.
Many of our water-based formulas use a preservative system based on benzyl alcohol and dehydroacetic acid. These preservatives are permitted under the COSMOS standard for natural and organic cosmetics.
No. Water-based skincare still needs effective preservation. Paraben-free means the formula uses a different preservative system instead of leaving the product unprotected.
Check the ingredient list for names ending in “paraben,” such as methylparaben, propylparaben, butylparaben or ethylparaben.
