Kiehl's Retinol Skin-Renewing Daily Micro-Dose Anti-Aging Serum is a precision-engineered formula that delivers all the benefits of pure retinol without the discomfort typically associated with this ingredient. Using microdose technology, this daily treatment helps reduce wrinkles, improve skin texture and firmness, and stimulate cell renewal, while strengthening the skin barrier and minimizing irritation.

Main ingredients

• Pure retinol
  It works by constantly and progressively accelerating cell renewal. It helps visibly improve signs of aging, such as fine lines, uneven texture, and dullness, revealing smoother, fresher, and more youthful skin.

• Peptides
  They promote skin integrity and optimize treatment effectiveness. Their action helps the skin adapt better to retinol, facilitating visible results without compromising skin comfort.

  Essential lipids found naturally in the skin. They strengthen the barrier function, improve treatment tolerance, and help maintain skin hydration and balance.
