Kiehl’s Revolutionizes Retinol with Breakthrough Retinol Skin-Renewing Daily Micro-Dose Serum

Kiehl’s first retinol serum, formulated for daily use

Retinol is regarded by dermatologists as the holy grail of skincare ingredients for its unique and clinically proven ability to visibly improve wrinkles and other key signs of aging by increasing surface skin renewal and restoring skin density and firmness.However, because of its potency, products containing retinol can also cause a variety of uncomfortable side-effects, including dryness, visible redness, and peeling –especially in the early stages of use. In most cases, retinol products need to be introduced into skincare routines gradually or at varying strengths to first build up the skin’s tolerance to the ingredient before seeing transformative benefits. Without expert guidance, this process can be confusing, inconvenient, and frustrating for the consumer.

To that end, Kiehl’s is proud to introduce Retinol Skin-Renewing Daily Micro-Dose Serum; a breakthrough approach to retinol, formulated in a precise daily-dosage that delivers visible anti-ageing benefits, while minimizing the uncomfortable side-effects associated with traditional retinol formulas –even within the first two weeks of use. Based onclinical evaluation, the patent-pending formula brings clinical efficacy with 100% of users showing reduced wrinkles, 90% showing improved firmness, and 94% showing refined texture within twelve weeks of use.1

Inspired by the medical science of “micro-dosing,” or the administration powerful ingredients in low and precise dosages, Kiehl’s newest serum innovation contains a carefully calibrated dose of retinol that works to steadily promote surface cell turnover. With each daily-strength dose, new cells are gradually brought to the surface for a fresh, renewed look to skin.

Alongside hero ingredient pure retinol, Kiehl’s newest innovation also contains ceramides and peptide in the formula to help fortify the skin barrier and increase skin’s tolerance to retinol starting from the very first use.

Kiehl’s Global Scientific Director, Dr. Nancy Ilayaexplains, “Our research tells us that for a skincare product to be effective, consistency and compliance are required for results. We wanted to formulate a retinol product that could be used every day from the start with minimal discomforting effects, while still offering powerful anti-aging skin benefits. To do so, our formula includes peptide to further support and sustain the repair benefits of retinol, and ceramides that release vital skin barrier lipids to help build retinol tolerance and prevent against dryness. The precise dose of retinol can then be effectively delivered into skin to begin providing benefits without over-accelerating cell turnover or disrupting the skin barrier. The results are the maximum efficacy of retinol, with minimal to no discomfort.”

This gentle, yet targeted formula can be used day or night and is suitable for all skin types, including sensitive skin. To use, simply apply 1 pump to cleansed skin followed by a moisturizer and a broad-spectrum SPF during the day for best results. This product can also be used on other areas where signs of skin aging can appear including the eye area, neck, décolleté, and back of hands. It’s compatible to layer over or under other Kiehl’s serums and moisturizers, such as Powerful-Strength Line-Reducing Concentrate, Clearly Corrective Dark Spot Solution, Super Multi-Corrective Cream, Hydro-Plumping and Vital Skin Strengthening Serum.
