Focus on skin type differences and enhance the ability of targeted care: Explain the key points of "dry skin" care (using high-hydrating essence in combination, applying moisturizing masks 2-3 times a week to relieve dryness and flaking, avoiding products containing alcohol that cause constricting effects); "oily skin" care logic (using oil-control cleansing products + salicylic acid toner to regulate water and oil balance, cleaning pores with a mud mask once a week to prevent acne, avoiding frequent oil control that leads to imbalance of water and oil); "combination skin" area-specific care (placing emphasis on oil-control and cleansing in the T-zone, strengthening hydration and moisturization in the U-zone, adjusting the frequency of care as needed); "sensitive skin" protection points (choosing non-irritating repair products, establishing a gradual tolerance-based care process, avoiding alternating between hot and cold temperatures and excessive cleansing).
