Product Details

The Kiehl's Retinol Fast Release Wrinkle-Reducing Night Serum features a potent 0.3% pure retinol in a unique powder-to-serum format. It is designed to be freshly mixed upon first use for maximum efficacy, visibly reducing fine lines in just 5 days and deep wrinkles in 2 weeks. [1] How It Works Fresh Activation: The innovative packaging isolates pure retinol powder, which you freshly mix into the serum base upon first use to ensure maximum potency. Deep Penetration: The 0.3% formula accelerates skin surface cell renewal and penetrates up to 15 surface layers deep. Visible Results: Clinically shown to improve both fine lines and deep wrinkles while leaving skin visibly renewed and smoother. [1, 2, 3]

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
