Joyce de Lemos
Clinical cosmetic chemist who formulated for SkinCeuticals and other prestige brands before co-founding Dieux Skin with Charlotte Palermino and Marta Freedman in 2020 — bringing the clinical-vetting discipline that anchors the brand's transparency-first promise.
"We test until it works. If it doesn't, we don't sell it."
— Joyce de Lemos
De Lemos is a clinical cosmetic chemist who spent years formulating for some of the industry's top prestige skincare brands, including SkinCeuticals.
She co-founded Dieux Skin as Chief of Product, leading formulation and clinical-testing strategy. The brand launched with the Forever Eye Mask — a reusable silicone alternative to single-use under-eye patches — and has since added clinically vetted serums and creams.
Clinical vetting is not a marketing line — it's whether or not the product ships.
Reusable beats disposable when efficacy is equal.
