The internet is a treasure trove of cosmetic information—if you know reliable sources. Wikipedia offers raw details on molecules, from discovery and composition to their roles (beyond just cosmetics). It's a strong foundation, but the scientific depth can overwhelm. Two trusted resources cut through the noise: Noteo* and EWG Skin Deep**.
• Noteo rates everyday consumer products, including cosmetics from top brands, on health, environmental impact, labor rights, social ethics, and affordability. It provides an overall score plus breakdowns per category—revealing, for example, products strong on health but weaker ethically. A heads-up: the database hasn't updated in months, so it's ideal for legacy products.
• EWG Skin Deep is an encyclopedic powerhouse. Search any active ingredient (we've tested dozens!), and get its full profile: health risks, functions, synonyms, and cited studies. Technical yet unparalleled in depth.
