History
Jean-Noël Thorel, a French pharmacist and cell-biology expert, founded the company NAOS and the brands Institut Esthederm, Bioderma and Etat Pur. From the 1970s he envisioned a new generation of cosmetics designed to interact with skin biology for lasting results, and conceived the first sun care products that activate melanin, the skin's natural protective pigment. The brand's history page lists founding products: in 1980, No Sun Soin Protecteur, a 100% mineral high-protection sun cream for skin intolerant or allergic to the sun, and Osmoclean Crème Douce Désincrustante, a cleansing product described as a founding step of Institut Esthederm's skin-preparation routine; in 1986, Bronz Repair Soin Protecteur Anti-Rides Fermeté, an anti-wrinkle sun care and tanning optimizer; and in 1999, Eau Cellulaire Brume, an antioxidant, energizing, hydrating booster mist.
