If you are on the look out for a quick, visible reduction in fine lines and wrinkles, you might want to check out Kiehl’s latest Retinol Fast Release Wrinkle-Reducing Night Serum—a clinically tested formula that is said to be able to penetrate up to 15 surface layers deep to begin accelerating skin surface turnover, visibly improving skin’s appearance in as little as five days! 

Regarded by dermatologists as one of the most researched and highly efficacious anti-ageing ingredients in skincare, retinol is widely recognised for its proven ability to help visibly diminish wrinkles and firm the skin’s appearance.

Unlike many over-the-counter retinol formulations, which can take several weeks or even months to start seeing improvements, Kiehl’s newest skincare innovation prioritizes speedy results. Featuring a cutting-edge ‘fast-release’ delivery system that contains 0.3% pure retinol, the fast-absorbing serum penetrates up to 15 skin surface layers deep accelerating skin renewal, helping to rapidly bringing fresh new skin cells to the surface for a more revitalized, youthful-looking complexion. 

In a clinical product study, skin showed visible improvement in the appearance in fine lines in just five days, as well as a reduction in wrinkles, and refined texture after two weeks of nightly use. In an eight-week consumer perception study, 80% of participants visibly demonstrated a reduction in wrinkles, including deep-set and stubborn wrinkles. 

Kiehl’s newest retinol advancement comes uniquely packaged in a dual-sided component that allows you to freshly activate their formula by releasing a pure retinol powder capsule into an ultra-lightweight serum base. To activate, the bottom bottle cap is replaced with a pure retinol capsule which is pressed down to release the powder into the serum. 

With this packaging and formula release method, retinol is preserved and protected from degradation to ensure optimal potency and efficacy from the very first use. This enables the formula to be rapidly delivered into the skin and accelerate skin surface renewal and in turn expedites visible results,” – Dr. Nancy Ilaya, PhD. Kiehl’s Global Scientific Director

Kiehl’s Retinol Fast Release Wrinkle-Reducing Night Serum is recommended for nightly use on skin that is already acclimated to retinol, so if you are a retinol newbie, you might want to patch test first to ensure you don’t breakout, or have an adverse reaction.
