At O&3, we understand the importance of hormone health in overall well-being. We’re committed to supporting the shift towards natural, toxin-free ingredients, empowering brands to create products that truly care for their customers.
Everyday life exposes us to a huge array of toxins.
From air pollution, plastics, and pesticides to synthetic chemicals in household, cosmetics, and personal care products, these toxins often include endocrine disruptors (compounds that can interfere with the hormonal system). And according to Science Alert, there were approximately 350,000 synthetic chemicals in use in 2022, a number that has only been growing since, as new chemicals are developed and introduced into the market. However, many have not been thoroughly tested for long-term safety.
For brands, understanding this connection isn’t just good practice, but is essential for meeting the demand for safer, more sustainable products.
So, join us today, as we explore the importance of hormone health in overall well-being, as well as the best natural alternatives to common endocrine disruptors, for creating products that fall in line with the growing demand for natural, toxin-free ingredients.
What is the hormonal system/endocrine system?
The endocrine system is made up of glands and organs that produce and regulate hormones, the body’s chemical messengers. It includes key glands such as the hypothalamus, pituitary, thyroid, adrenal glands, pancreas, and ovaries or testes. These glands work together to maintain balance and regulate critical bodily functions.
Hormones are responsible for controlling growth, metabolism, reproductive health, mood regulation, energy levels, and stress responses, among many other functions. They play a vital role in maintaining homeostasis, the body’s internal balance, ensuring that various systems function correctly. When the endocrine system is disrupted, it can affect everything from sleep patterns to fertility, immune function, and overall health.
Some substances applied to the skin can be absorbed, but not everything penetrates deeply or enters the bloodstream. The skin acts as a protective barrier, although certain chemicals in skincare products may still be absorbed in small amounts. While many of these chemicals are safe at regulated levels, some may raise concerns, especially if they contain endocrine-disrupting chemicals (EDCs).
EDCs are substances that can interfere with the normal functioning of the endocrine system by mimicking or blocking hormones and can even alter hormone levels. They are found in some skincare products, as well as in food, water, and the environment. Over time and with significant exposure, these chemicals may contribute to hormonal imbalances or health issues.
Why should cosmetic and indie brands be taking notice?
Hormonal imbalances don’t just affect internal health, they also manifest externally. Skin health, energy levels, and even confidence can suffer when the endocrine system is disrupted. This creates an opportunity, and arguably, a responsibility for brands to stand out by offering products that align with the growing consumer preference for toxin-free options.
Challenges such as raising awareness of endocrine disruptors and the rise in hormone-related health conditions emphasise the need for brands to provide innovative, clean, and trustworthy formulations.
So, by being mindful of the ingredients in skincare and personal care products, together we can reduce consumers’ potential exposure to EDCs and support their overall hormonal health, as well as our planet.
Why choose natural ingredients over synthetic ingredients for hormone health?
As consumers become more aware of their hormone health and EDCs, the choice between natural and synthetic ingredients is more important than ever. Opting for natural ingredients makes a significant difference to not only consumers, but our planet as well:
Reduced risk of endocrine disruption
As we have already touched on, natural ingredients, such as plant-based oils and extracts, are free from the artificial compounds found in synthetic ingredients, offering safer alternatives for people looking to protect their hormonal systems.
Biocompatibility with the body
Natural ingredients are often more easily recognised and processed by the body. For example, plant-derived oils, rich in nutrients and bioactive compounds, can support the skin’s natural barrier without the risk of introducing synthetic toxins. This compatibility reduces the likelihood of irritation and negative long-term effects on the endocrine system.
Sustainability and consumer trust
Natural ingredients are often sustainably sourced, especially at O&3, aligning with the values of eco-conscious consumers. Brands that prioritise natural formulations gain a competitive edge by building trust with consumers who are increasingly aware of the connection between synthetic chemicals and hormone health.
Efficacy without compromise
Many natural ingredients, such as essential oils and cold-pressed carrier oils, are not only safe but also highly effective. They provide the benefits consumers seek, including hydration, nourishment, anti-ageing effects (to name a few!), while supporting overall wellness.
A natural approach to health and wellness
Choosing natural over synthetic goes beyond skincare. It’s a step towards natural well-being, empowering individuals to take control of their exposure to toxins. By minimising synthetic chemicals in personal care, consumers can reduce the toxin loads that may interfere with their hormonal systems over time.
Which synthetic ingredients to avoid and the best natural alternatives for hormone balance?
By replacing synthetic ingredients with natural alternatives, brands can create safer, effective formulations that protect and promote hormonal balance while meeting consumer demand for cleaner, toxin-free products. Here are some of the most common endocrine disruptors and potential natural alternative options:
Parabens – Parabens are commonly used as preservatives but mimic oestrogen, potentially disrupting hormonal balance.
Try these natural alternatives instead:
Vitamin E (tocopherol) – A natural antioxidant that extends shelf life while nourishing the skin.
Neem oil – Best suited for oil-based formulations, neem oil has natural antimicrobial properties that protect products from spoilage. Best suited for oil-based formulations.
Tea tree oil – Effective against bacteria and fungi, though it’s most useful in smaller concentrations due to its strong scent.
Phthalates – Used to stabilise synthetic fragrances, phthalates can interfere with testosterone production and overall hormone function.
Try these natural alternatives instead:
Essential oils – Provide a rich, natural aroma without harmful chemicals.
Absolutes – Intensely aromatic, they add luxury to formulations.
Natural Distillates – Refreshing options for clean, uplifting aromas, such as peppermint and lime.
BHA and BHT (Butylated Hydroxyanisole and Butylated Hydroxytoluene) – Synthetic antioxidants used to prevent oxidation in products, they mimic oestrogen and may disrupt reproductive health.
Try these natural alternatives instead:
Sea buckthorn oil – Rich in carotenoids, tocopherols, and flavonoids, this oil protects oils and emulsions from oxidation while providing skin-nourishing benefits.
Avocado oil – High in monounsaturated fats and Vitamin E, this oil stabilises emulsions while adding skin benefits.
Black cumin seed oil – Contains thymoquinone, a natural preservative and antioxidant that protects against free radical damage in oil-based formulations.
Silicones (e.g. Dimethicone, Cyclopentasiloxane) – While not directly endocrine disruptors, silicones can occlude skin and trap toxins, increasing potential exposure.
Try these natural alternatives instead:
Aloe vera gel – Provides a lightweight, hydrating base that smooths skin without clogging pores.
Mango butter and kokum butter – Lightweight yet nourishing alternatives for smoother, non-greasy finishes.
O&3 Thoughts…
For brands, transitioning to natural formulations isn’t just a trend, it is a meaningful response to the growing demand for products that prioritise safety and transparency. Embracing natural ingredients not only supports hormone health but also positions your brand as a leader in the natural, toxin-free beauty revolution.
