Delivers Remarkable Immediate Effects, Both Internally and Externally

Kiehl's new whitening serum, Kiehl's Clearly Corrective Dark Spot Solution, features a flawless, thorough whitening approach that not only suppresses melanin production but also targets existing melanin. Its star ingredient is "Active C," a next-generation active vitamin C. It delivers remarkable immediate effects, working effectively both inside and outside the skin.

Catching existing melanin means preventing dark spots before they form. Kiehl's highly anticipated whitening active ingredient, Active C, is said to efficiently block the process by which melanin transforms into dark spots. Furthermore, its rapid absorption, superior stability compared to conventional vitamin C derivatives, and immediate action upon application make it a highly attractive whitening ingredient. This ensures that the whitening effect is more powerful and lasts longer. In addition, the synergistic effect with natural ingredients "Peony Extract" and "White Birch" further enhances its whitening action! The immediate effect is truly astonishing. "Active C," which activates within the skin, is a reliable next-generation active vitamin C that exerts its maximum power from the moment it's applied.

The transparent bottle, made possible by the ingredient's stability, is a testament to its clarity. Its pristine appearance is symbolic of the clear, translucent skin it helps achieve, inspiring a sense of motivation. The slightly viscous texture glides onto the skin and absorbs smoothly, leaving a comfortable finish. This "transparent serum" deeply improves dark spots and dullness while providing ample moisture, leading to radiant, bright skin. It's destined to become a signature item for Kiehl's.

The Kiehl's Clearly Corrective line also includes a facial cleanser, a scrub cleanser, a medicated whitening lotion, and a medicated whitening emulsion, for a total of five products.
