Sustainability

score : 6.7/10

Packaging

Many products use recycled and recyclable materials: for example, Instant Angel moisturizer comes in a 100% PCR (post-consumer recycled) aluminum tube that is fully recyclable, and the Deliverance serum’s cap is 50% PCR plastic with a fully recyclable bottle. The brand avoids excess packaging; products ship in recyclable cardboard, and designs are kept lightweight to cut carbon shipping costs. Notably, the Forever Eye Mask is packaged in a reusable metal tin with a minimal plastic insert, aligning with the product’s goal of replacing single-use sheet masks. While some plastic components (e.g. pumps, caps) are still used, Dieux is actively working on improvements (e.g. exploring mono-material pumps) and provides detailed recycling instructions to consumers.

Ingredient Sustainability

Across sampled formulations, Dieux Skin favors ingredients that are lab-crafted or ethically farmed to reduce ecological strain. Common synthetic actives like niacinamide, glycerin, peptides, and cannabinoids are produced in controlled settings, avoiding the environmental toll of wild-harvesting scarce botanicals. Natural oils and extracts used (meadowfoam seed oil, rosemary extract, colloidal oatmeal, etc.) are generally from renewable plant sources with lower resource intensity. Some richer plant butters (shea butter, illipe butter from Shorea trees) appear in small amounts; while these can raise sustainability questions (illipe is wild-harvested in Borneo rainforests), Dieux has stated it selects suppliers based on environmental benchmarks and sustainable sourcing practices. Notably absent are highly problematic inputs like non-renewable microplastics or unsustainably sourced palm oil.

Energy Use and Footprint

Dieux Skin shows some mindfulness of its carbon footprint, though mostly through indirect measures. Production is localized. The brand formulates in-house at its Brooklyn, NY lab and is not reliant on overseas contract manufacturers. This likely shortens supply chains and avoids excessive freight emissions. In packaging, Dieux opts for lightweight materials (aluminum tubes, minimal outer boxes) specifically to “reduce carbon footprints in shipping”. The company offers U.S. customers free shipping (orders $60+), and some sources indicate that shipping is carbon-neutral via partner services (Route) that offset delivery emissions. However, Dieux has not published any GHG emissions data or formal reduction targets, and there’s no evidence of a renewable energy program or comprehensive carbon neutrality across operations.

Waste Management

The flagship Forever Eye Mask exemplifies waste mitigation: it’s “the last eye mask you’ll ever buy,” replacing countless single-use sheet masks with a durable silicone patch. By encouraging reuse literally forever, this product alone diverts a significant stream of cosmetic waste (and third-party analysis shows using it for a year saves considerable carbon, water, and landfill burden versus disposables). Beyond products, Dieux incorporates recycled inputs (e.g. tubes made of recycled aluminum and 50% PCR plastic caps), thereby using waste from other industries and closing the materials loop. They also emphasize getting every drop out (providing a metal “squeeze key” for tubes) so products aren’t wasted.

Business Model

Dieux Skin’s business model strongly favors slow, sustainable consumption over trend-driven sales. Since launching in 2020, the company has kept a tight, “evergreen” product assortment. Only a handful of SKUs (cleanser, serum, moisturizers, eye mask, eye gel) have been introduced.

Non-toxicity

score : 9.0/10

All products are free of known high-risk toxins: they contain no parabens, formaldehyde releasers, phthalates, or other dangerous chemicals. Instead, the formulas rely on gentle, well-studied actives (niacinamide, ceramides, peptides) and use mild preservatives at low concentrations (phenoxyethanol and caprylyl glycol, which are globally approved and used at safe levels). The brand avoids potential irritants like added fragrance or essential oils in most products (a scented version of the cleanser is offered, but a fragrance-free version exists for sensitive users). The few ingredients carrying moderate hazard in certain contexts (e.g. phenoxyethanol can cause mild irritation for some; PEG-100 stearate may have trace impurities) are used within safe limits and with disclosure. The result is products deemed safe for sensitive skin.

Social Responsibility

score : 6.3/10

Fair Labor

The brand has a Supplier Code of Conduct aligned with Good Manufacturing Practices that forbids forced or underage labor, unsafe or harassing work conditions, and discrimination in any partnering facility. In short, they require that workers making their products have fair wages and a safe environment. Because a significant portion of Dieux’s production and R&D is done in-house or locally (Brooklyn lab), there is greater oversight of labor conditions than there would be with overseas mass production.

They do not (yet) publish a detailed supplier list or third-party audit results. Also, while they mention choosing some certified ingredient suppliers (for quality/purity), we haven’t seen specific fair-trade certifications tied to their ingredients (e.g. fair-trade shea). It’s possible they do use some but haven’t advertised it.

Animal Welfare

All products are 100% vegan and cruelty-free. They do no animal testing at any stage (relying on human volunteer testing and in vitro methods), and they do not sell in countries that require animal testing. The brand has made no attempt to bypass regulations that would compromise their cruelty-free stance.

Community Engagement

Community and social responsibility are deeply woven into Dieux Skin’s identity. The brand consistently leverages its platform and profits to support social causes. Far beyond what most skincare companies do. Notably, in January 2026, Dieux announced it would donate all profits from a day’s sales to organizations aiding communities in Minnesota impacted by ICE (Immigration and Customs Enforcement) raids. This came after the brand and its customers collectively raised $5,000 for Minnesota schools, to which Dieux themselves added another $10,000. In total, Dieux ended up donating $140,000 to support Minnesotans affected by these immigration enforcement actions. Additionally, Dieux has an ongoing partnership with the Floret Coalition (an anti-racist collective of beauty brands); for example, they donate $1 from every sale of Deliverance serum to this coalition’s fund for BIPOC and social justice causes (as shared on social media).
