Retinol is a powerful skincare ingredient derived from vitamin A that encourages skin cell turnover, helping to visibly reduce signs of aging such as fine lines, wrinkles, and uneven texture. Within the Kiehl’s Retinol Skincare collection, this ingredient plays a central role in promoting a smoother, more youthful-looking complexion.

Retinol is typically introduced into a skincare routine when early signs of aging, such as fine lines, dullness, or uneven skin texture, start to appear. Kiehl’s Retinol Skin-Renewing Micro-Dose Serum , for example, is suitable for daily use and can be applied in either your AM or PM routine, depending on your preference.

Whether you're using a serum, cream, or treatment, consistency is key, and daily sun protection is essential when using retinol.
