Kiehls A醇精華4ml

$38@5, $60@10 This Kiehl's A醇 serum is like a "time machine" for your skin! Formulated with a golden ratio of gentle yet effective A醇, it precisely smooths fine lines, tightens pores, restores skin's smoothness and elasticity, and reveals a youthful glow. Even sensitive skin can safely experience the power of advanced anti-aging. How to use: Use after cleansing: In the morning or evening, apply after completing cleansing and toning steps. Apply an appropriate amount: Dispense about 2 to 3 pumps into the palm, gently spread evenly, then apply uniformly to face and neck. Enhance sun protection: A醇 increases skin's sensitivity to light. If used during the day, be sure to apply sunscreen with SPF 30 or higher. Maintain hydration: To minimize potential dryness or peeling, follow up with moisturizing products after use. Initial adaptation: For first-time users or those with sensitive skin, it is recommended to start 2 to 3 times per week, gradually increasing frequency as the skin adapts.
