What is the 4-2-4 Rule in Skincare?

The source provides an extensive guide to the 4-2-4 Korean skincare cleansing rule, a structured method emphasizing thorough facial hygiene to achieve radiant skin. This technique, rooted in K-beauty philosophy, is a form of double cleansing that allocates specific durations for three phases: four minutes of oil-based cleansing, two minutes of water-based cleansing, and four minutes of rinsing using both warm and cold water. The episode explains that the process ensures the removal of both oil-based and water-based impurities, promoting better product absorption and skin circulation. While the method is generally beneficial for most skin types, the source advises that individuals with sensitive skin should exercise caution due to the extended timing and temperature changes."Fashion fades, only style remains the same." – Coco Chanel
