Retinol Skin-Renewing Daily Micro-Dose Serum

Retinol is an anti-ageing ingredient renowned for its ability to increase skin cell production, which surfaces new cells to skin's outermost layer. This helps to visibly reduce signs of ageing like fine lines and wrinkles, dark spots and dullness.

Although vitamin C and retinol cannot be layered directly on top of each other, the two ingredients make a powerful combination to improve skin clarity and protect against visible ageing. We recommend pairing the Kiehl's micro-dose anti-ageing retinol serum with the Clearly Corrective Dark Spot Solution to achieve youthful, glass-like skin. Apply the vitamin c serum in the morning and your retinol face serum at night. Always use SPF in the morning. Learn more about Kiehl's retinol percentages with our 'How much retinol to use' guide.
