Kiehl’s Dermatologist Solutions Retinol Fast Release Wrinkle-Reducing Night Serum is a powerful anti-aging treatment formulated to target visible signs of aging with fast-acting results. The innovative two-step system includes pure retinol powder and a lightweight serum base, which are freshly mixed upon activation to preserve potency and maximize performance.
Designed for nighttime use, the formula penetrates deeply to accelerate surface skin cell turnover, visibly reducing the appearance of fine lines, deep wrinkles, and uneven skin texture. The concentrated retinol works to firm the skin and smooth its overall appearance while supporting long-term improvements in skin clarity and elasticity.
Despite its strength, the formula is developed to balance efficacy with tolerability, making it suitable for experienced retinol users or those gradually building a routine. With continued use, skin feels firmer, looks smoother, and appears more youthful.
The packaging includes 0.94 fl oz (28 ml) of serum and 0.03 fl oz (1 g) of pure retinol powder, activated by combining the two before the first application.
