Dieux Introduces Sun-Screener

Dieux Introduces Sun-Screener

Charlotte Palermino and Joyce de Lemos, co-founders of skincare brand
Dieux, are tackling one of beauty's most confusing and misunderstood
categories: sunscreen. The clinical brand has
introduced Sun-Screener, a free online tool designed to help
consumers decode the ingredients in their SPF products and navigate
the widespread misinformation surrounding sun protection,
particularly the use of the term 'mineral'.

Mineral sunscreens are often marketed as gentler alternatives to
chemical formulas, making them a popular choice for those with
sensitive skin, pregnant women, or consumers seeking reef-safe or
natural options. Yet, despite their appeal, not all products labelled
'mineral' are created equal. Some rely on vague phrases like
"mineral-based" or "enriched with minerals" while still leaning
heavily on chemical UV filters. Others may feature zinc oxide or
titanium dioxide in trace amounts, misleading consumers into
believing the formula is exclusively mineral.

Sun-Screener tool

Enter Sun-Screener. By pasting an ingredient list into the online
analyser, users receive a detailed breakdown of their sunscreen's
active components: whether it uses mineral or chemical filters (or
both), which UV boosters are present, and what role each inactive
ingredient plays. The tool also explains how each filter works,
outlines its strengths and limitations, and notes whether it's
approved for use in the US or EU.

Sun-Screener results

Developed in collaboration with cosmetic chemists Rebecca Perry and
Ava Perkins, Sun-Screener draws from peer-reviewed data to provide
insights into more than 35 UV filters, from zinc oxide and titanium
dioxide to avobenzone and octocrylene. An accompanying glossary
offers accessible explanations of sunscreen formulations, the
distinction between mineral and chemical filters, and the types of UV
radiation consumers need to be aware of.

Founded in New York City in 2020, Dieux combines expertise in brand
strategy, cosmetic chemistry, and community building to deliver a
science-driven, transparent approach to skincare. The brand champions
rigorous clinical vetting, ethical sourcing, and vegan, cruelty-free
practices, and is best known for its product transparency -- breaking
down each product's formula, clinical testing, recyclability, and
sustainability impact.

The brand's bestsellers include the Instant Angel Moisturizer, a rich
cream formulated to support skin recovery and maintain a healthy
barrier, and the Forever Eye Mask, a set of lightweight, reusable
patches that hold skincare products in place to enhance absorption
and maximise results.

Sun-Screener is now available at dieuxskin.com.
