Understanding How Parabens Can Affect Hormones
Medical Reviewed By Lucas Rosa
Discover how a common group of preservatives in everyday products can disrupt our hormones.
What Are Parabens?
Parabens are a group of synthetic chemicals that are commonly used as preservatives in a variety of consumer products including cosmetics, personal hygiene, pharmaceuticals, cleaning products, and food items. They are highly effective in preventing the growth of harmful bacteria and mold which extends the shelf life of these products.
You can find parabens listed under various names on ingredient labels, such as methylparaben, ethylparaben, propylparaben, isopropylparaben, butylparaben, and isobutylparaben.
Although these chemicals are effective as preservatives, there is some concern. Scientific studies suggest that parabens can disrupt our hormones, it is suggested that they can mimic estrogen and lead to a variety of health issues.
Scientists are on alert, and lots of research is still ongoing to figure out if the current concentration and exposure of parabens are harmful.
How Parabens Can Enter Our Bodies
Parabens have been detected in all ages from infants to the elderly. Throughout all the stages of our lives we can be exposed to parabens, and there are three main ways that parabens can enter our bodies.
The most common route is through skin contact, applying products that contain these preservatives can lead to these chemicals entering our bodies. These chemicals can be absorbed directly into the bloodstream.
In addition to skin contact, parabens can be digested by consuming foods, drinks, or pharmaceuticals with these preservatives in them. Once inside the body, parabens are metabolized by the liver and excreted in the urine, but some parabens can accumulate in fat tissue over time.
The last common route of exposure to parabens is inhalation. The spraying of products that contain parabens can cause us to breathe in these chemicals. Also, these chemicals can accumulate in dust particles which can be inhaled.
Parabens Can Mimic Estrogen
Parabens interfere with the functioning of the endocrine system which is responsible for hormone production and regulation, and this interference can lead to hormonal imbalances.
Parabens mimic the activity of estrogen by binding to estrogen receptors in cells. It acts like estrogen and can potentially artificially trigger similar biological responses that estrogen would trigger. For example, estrogen can increase cell proliferation, so parabens could artificially increase cell proliferation which could lead to the growth of tumors and possibly cancer.
The estrogenic activity of parabens is weaker than that of natural estrogen, but low-level exposure over long periods can lead to hormonal imbalances. This imbalance can affect reproductive health, development, and potentially lead to hormone-related cancers.
Tips For Avoiding Parabens
As awareness of the potential risks associated with parabens grows, many manufacturers are seeking alternative preservatives. Natural preservatives like grapefruit seed extracts or essential oils are increasingly being used in place of parabens.
To avoid parabens, look for products labeled as 'paraben-free'. Natural and organic products are not guaranteed to be paraben-free, so it is important to carefully read the labels on products. Additionally, DIY beauty products made from natural ingredients can be a safe and effective alternative.
Here are some companies that have paraben-free products:
- EcoRoots - has eco-friendly and low-waste personal care products
- Urban Apothecary - has plant-powered skincare products
- Primally Pure - has non-toxic skincare products
- Blueland - has sustainable cleaning products
- Osea - has clean skincare that is naturally infused with seaweed
- Activist Skincare - has natural, non-toxic, and refillable skincare
- Mrs. Meyer's - has plant-derived cleaning products
You can do a quick Google search to find more companies that are paraben-free.
Conclusion
Parabens are in many consumer products, but their potential to disrupt hormones raises concerns. Understanding how parabens can enter our bodies and what products they are in is crucial for making informed choices about the products we use.
By seeking healthy alternatives and being mindful of the labels on products, we can reduce our exposure to these hormone-disrupting chemicals and protect our hormonal health and overall well-being.
