I know that L'Oreal and Lancome are owned by the same company, who also own Garnier, Maybelline, Kérastase, Redken, Matrix, Shu Uemura, Biotherm, Helena Rubinstein, Kiehl's Shu Uemura, Giorgio Armani, Ralph Lauren, Cacharel, Viktor & Rolf, Diesel, YSL Beauté, Vichy, Skinceuticals and The Body Shop!
Estee Lauder owns all these other companies, Clinique, MAC, Prescriptives, Origins, Creme de la Mer, Bobbi Brown, Aveda, Jo Malone, Bumble and Bumble and Darphin. And a whole lot more.
I am 30, and I use By Terry's Gelee de Rose as my main moisturiser, its gorgeous! Don't know who that belongs to though
