Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum

Kiehl’s Retinol Skin-Renewing Daily Micro-Dose Serum is a premium anti-aging skincare product designed to promote cell turnover and improve skin texture. The brand's history dates back to 1851, when it began as a single homeopathic pharmacy in Manhattan's East Village, New York City. Since its founding by John Kiehl, the brand has built a reputation for using high-quality botanical ingredients and scientific innovation.

In 2000, the brand transitioned from a family-owned business to a global skincare powerhouse when it was acquired by L'Oréal. Today, Kiehl's operates as a key brand within L'Oréal's Luxe division. While many products are still formulated and manufactured in the United States to maintain the brand's New York heritage, the global supply chain of L'Oréal means that packaging and production may occur in various international facilities to meet global demand.
