Paste time, lemon and sugar, and what to do after you scrape.
Keep the paste on for 6 to 8 hours or overnight. Dab it with lemon and sugar so it stays moist. After scraping, avoid water for the first hours and rub on a thin layer of oil. The colour usually peaks after 24 to 48 hours. It varies from person to person, so we never promise a shade.
