Harmful ingredients
Is Your Skincare Product Damaging the Environment? A Dermatologist’s Sustainability Guide
Introduction
In our pursuit of glowing skin, we often overlook a crucial question—at what environmental cost? With millions of cosmetic and skincare products washed down our drains daily, it’s time we consider the ecological footprint of our beauty routines. As a dermatologist advocating for skin health and sustainability, I believe it’s imperative to educate consumers about how certain ingredients in skincare not only affect the skin but also damage the environment.
Why Should We Care?
Every product we apply eventually enters the environment—via wastewater systems, landfill disposal, or even direct contamination through packaging. Microplastics, chemical UV filters, silicones, and persistent preservatives find their way into oceans, freshwater systems, and soil, harming aquatic ecosystems, disrupting marine life, and sometimes re-entering our bodies through the food chain. The beauty industry, unfortunately, is among the top contributors to this silent pollution.
Effects of Environmentally Harmful Skincare Ingredients
Aquatic toxicity: Many ingredients do not degrade easily and can poison aquatic life.
Bioaccumulation: Some compounds accumulate in marine organisms, working their way up the food chain.
Hormonal disruption in wildlife: Ingredients like UV filters mimic hormones and disrupt reproduction in fish and other animals.
Soil degradation: Persistent ingredients alter soil microbiota and fertility.
Air and carbon pollution: Volatile compounds from sprays and propellants can contribute to smog and greenhouse gas emissions.
List of Ingredients and Their Environmental Impact
Ingredient | Function in Skincare | Environmental Impact |
|---|---|---|
Oxybenzone (Benzophenone-3) | Chemical sunscreen | Coral bleaching, endocrine disruption in fish |
Octinoxate (Ethylhexyl Methoxycinnamate) | UV filter | Coral reef damage, hormone disruption |
Triclosan | Antibacterial | Toxic to algae, bioaccumulative |
Parabens (e.g., methylparaben, butylparaben) | Preservative | Hormonal disruption in aquatic life |
Silicones (e.g., dimethicone, cyclopentasiloxane) | Texture enhancer | Persistent in environment, toxic to aquatic organisms |
Microbeads (Polyethylene, Polypropylene) | Exfoliants | Non-biodegradable, ingested by marine life |
Phthalates (e.g., DEP) | Fragrance stabilizer | Hormonal disruptor, accumulates in water and soil |
Formaldehyde releasers (e.g., DMDM Hydantoin) | Preservative | Toxic to aquatic organisms |
Sulfates (e.g., SLS, SLES) | Surfactant | Toxic to aquatic life in high concentrations |
Petrolatum and Mineral Oil | Emollient | Non-renewable source, potential to contaminate ecosystems |
Synthetic Fragrance (undisclosed mixtures) | Scent | May contain VOCs and phthalates, air and water pollution |
Silicone and Dermatocare List of Harmful Ingredients
We have only included cyclic silicones (also known as cyclic volatile methylsiloxanes or cVMS), in our list of harmful ingredients because they are the most concerning from an environmental perspective.
INCI Name | Common Name | Structure Type | Why Harmful |
|---|---|---|---|
Cyclopentasiloxane | D5 | Cyclic | Bioaccumulative, persistent in aquatic environments |
Cyclotetrasiloxane | D4 | Cyclic | Known endocrine disruptor, very persistent |
Cyclohexasiloxane | D6 | Cyclic | High potential for bioaccumulation |
Octamethylcyclotetrasiloxane | Often referred to as D4 | Cyclic | Persistent, toxic, bioaccumulative |
These silicones usually end in “-siloxane” and start with “Cyclo-”
Examples: Cyclopentasiloxane, Cyclotetrasiloxane
They are lightweight, volatile, and commonly used in products for a silky finish or quick dry-down (e.g., hair serums, primers, sprays).
We have excluded linear or non-volatile silicones from our harmful ingredient list. Although these compounds are not fully biodegradable, they exhibit low potential for bioaccumulation and are generally considered less toxic to aquatic ecosystems. Additionally, our product analysis indicates that these silicones are commonly used across the skincare industry at present.
INCI Name | Common Name | Structure Type | Environmental Profile |
|---|---|---|---|
Dimethicone | Dimethicone | Linear | Non-volatile, low toxicity, not prone to bioaccumulation |
Amodimethicone | Modified dimethicone | Linear | Not persistent, less bioaccumulative |
Phenyl Trimethicone | Trimethicone | Linear | Less volatile, low toxicity |
Dimethiconol | Dimethiconol | Linear | Considered safer, forms film on skin/hair |
How Can You Contribute to Greener Skincare?
Read the Label: Learn to recognize ingredients that are persistent, bioaccumulative, and toxic (PBTs).
Choose Reef-Safe Sunscreens: Opt for mineral-based sunscreens like zinc oxide or titanium dioxide in non-nano forms.
Go Microbead-Free: Use natural exfoliants like oatmeal, sugar, or ground seeds.
Limit Fragrance: Opt for fragrance-free or naturally scented products.
Support Green Brands: Choose companies with eco-certifications, biodegradable packaging, and transparent sustainability policies.
Minimalism Works: Fewer products = less waste. Choose multi-functional products when possible.
Recycle Thoughtfully: Clean and recycle packaging; consider refills or return programs where available.
Advocate: Share your knowledge with others and demand more accountability from beauty brands.
Acrylates and Microplastic pollution
Acrylate-based ingredients, such as Acrylates Copolymer, Polyacrylate-13, Carbomer, and Acrylates/C10-30 Alkyl Acrylate Crosspolymer, are commonly used in skincare for their thickening, film-forming, and stabilizing properties.
However, these synthetic polymers are non-biodegradable and can persist in aquatic ecosystems, contributing to microplastic pollution. Once washed off, they may accumulate in water bodies, disrupt aquatic life, and enter the food chain. Due to their environmental persistence and potential to bioaccumulate, acrylates raise significant concerns regarding long-term ecological damage.
INCI Name | Function | Concerns |
|---|---|---|
Acrylates Copolymer | Film former | Microplastic-like persistence |
Carbomer | Thickener | Non-biodegradable |
Polyacrylate-13 | Emulsifier | Environmental persistence |
Acrylates/C10-30 Alkyl Acrylate Crosspolymer | Emulsifier/stabilizer | Aquatic pollution risk |
Acrylamide Copolymer | Texture enhancer | May contain acrylamide, a known neurotoxin in trace forms |
Conclusion
Being conscious of skincare’s environmental impact is not just a trend—it’s a responsibility. As dermatologists and consumers, we must champion sustainable choices that safeguard both skin health and planetary health. At Dermatocare, we have included these environmentally harmful ingredients in our “Harmful Ingredient List” while reviewing products to ensure our recommendations are aligned with both dermatological safety and ecological responsibility. Our regime and product suggestions are increasingly curated with a focus on green chemistry, biodegradable formulations, and minimal environmental footprint.
