Glass Skin Routine

What does an ingredient name mean? How do toner, essence and serum differ? What goes on first? Glass Skin Routine gives you quick, simple K-beauty explanations in a calm, magazine-inspired guide. Start with ingredient clues, compare product types, or explore a morning and evening layer-order diagram. You can browse without adding any products. • Read familiar ingredient names and label clues, with limitations and supporting sources. • Compare toner, essence and serum by role and texture. Extra steps are optional. • Understand basic morning and evening layer order, including when product-specific instructions take priority. • Explore skin goals and save ingredient guides to revisit. • Keep names and notes for products you already own on a local Shelf, with a small routine map. • Send optional feedback without an account or email field. Feedback is stored privately for up to 90 days to help improve the app. Available in English, Korean, Japanese, Chinese, Polish and Persian/Farsi. Guide content and saved products work offline; ads and sending feedback require a connection. The full privacy policy is available inside the app in English. No account, camera, face scan, skin score, reminders or streaks. Shelf products and notes stay on your device. Free, supported by banner ads. Glass Skin Routine provides general cosmetic education. It does not diagnose conditions, provide medical advice or guarantee results. Ingredient names alone cannot determine how a complete formula will work for your skin.
