LANCOME Genifique Advanced N 100ml Serum A serum used on bare skin after lotion. This serum targets 10 signs of skin quality—radiance, clarity, smoothness, luminosity, a healthy-looking appearance, refined texture, elasticity, softness, firmness, and hydration—guiding skin toward a more youthful look. It helps refine the skin for a soft, polished, and finely textured appearance. The texture is fresh, lightweight, and crystal clear. How to Use: Morning and evening, immediately after cleansing, take an appropriate amount (3 to 4 drops) and gently apply over the entire face and down to the neck.
