Reveal a smoother, brighter, and more youthful-looking complexion with Kiehl's Powerful-Strength Line-Reducing Concentrate 3.4 oz (100ml). This potent facial concentrate is designed to visibly improve the appearance of fine lines, wrinkles, uneven skin tone, and texture while providing hydration with hyaluronic acid. Kiehl's describes it as a powerful anti-wrinkle serum formulated with Vitamin C and Hyaluronic Acid.

The current formula combines 10.5% L-Ascorbic Acid, 2% Ascorbyl Glucoside, and Hyaluronic Acid, delivering antioxidant Vitamin C benefits while supporting smoother and more hydrated-looking skin. Kiehl's describes the concentrate as a patented, water-free formula and highlights its ability to address visible signs of aging and uneven skin tone.

Vitamin C is a popular skincare ingredient for improving the appearance of dullness and uneven-looking tone, while hyaluronic acid helps support skin hydration. The combination makes this serum a strong choice for customers seeking an advanced daily anti-aging skincare treatment.

The 3.4 oz / 100ml size is a generous full-size format and is ideal for customers who use facial serums regularly. Its concentrate texture fits easily into a morning or evening skincare routine, alongside moisturizer and sunscreen.
