Highlights

Description

This is a serum from Kiehl's formulated as an anti-aging treatment. The brand says it contains a 10.5% concentration of vitamin C alongside hyaluronic acid, a humectant that attracts water to the skin. Per the brand, the formula has been clinically demonstrated to improve skin texture, tone, and radiance while reducing the appearance of fine lines. The hyaluronic acid helps maintain moisture so skin doesn't feel dry—a condition the brand notes can accentuate the look of wrinkles.

The serum comes in a 100 ml pump bottle and is alcohol-free, dye-free, and paraben-free. Per the brand, it is suitable for all skin types, including sensitive skin, and is dermatologist-tested and non-comedogenic. You can use it morning and night as part of your routine. The trade-off is that targeted serums are an additional step; this works best alongside a consistent sunscreen regimen and other foundational skincare habits.
