New York, NY – As pioneers in Vitamin C skin care, Kiehl’s has long understood the benefits of the ingredient and demonstrates extensive expertise in incorporating this potent ingredient at its most beneficial concentrations.

In 2005, Kiehl’s Powerful-Strength Line-Reducing Concentrate was launched as a cutting-edge product with 10.5% pure, stabilized Vitamin C – a formula that has remained one of the most popular, highly efficacious formulas on the market for over a decade. The original Powerful-Strength Line-Reducing Concentrate, which boasts hundreds of 5-star reviews online and numerous awards, sells at a rate of one per minute around the world, with more than 5 million bottles sold to date.

After 89 trials and years of perfecting, Kiehl’s is proud to announce the next breakthrough in Vitamin C, and the Company’s largest formula renovation in 166 years. This advanced formula has a heightened potency of 12.5% Vitamin C (10.5% Pure Vitamin C [LAscorbic Acid] and 2% Vitamin Cg [Ascorbyl Glucoside]), and is now made with Hyaluronic Acid, making it more effective than ever before. The new powerful, antioxidant-packed formula provides clinically-demonstrated1 performance and now has an even more pleasant application experience, featuring a fast-absorbing, non-oily texture. The product, which warms as it activates on the skin, now features a pleasant citrus scent as well, from the addition of essential oils.

The powerful, fast acting, anti-aging serum has undergone a state-of-the-art reformulation that amplifies the efficacy of the original, making it work better and faster. The result is an anti-aging serum clinically demonstrated1 to provide intensified results, including visible improvement on lines, wrinkles, radiance and texture, faster than ever before.

“Powerful-Strength Line-Reducing Concentrate has been a standout favorite amongst our customer base since its initial release in 2005. As anti-aging serums have become an integral part of skin routines around the globe, we have remained vigilant in developing efficacious products for our customers,” says Chris Salgardo, President of Kiehl’s US. “It was important to us to maintain the qualities of the original formula that our customers already loved, while simultaneously delivering an improved formula that would stand up to our clinical study standards.”

“Our renovated formula, now with Hyaluronic Acid and a greater amount of Vitamin C, provides faster, better results,” says Dr. Geoff Genesky, Scientific Director at Kiehl’s. “While Vitamin C is difficult to stabilize within a formula, the team worked meticulously to stabilize even more Vitamin C and deliver our most efficacious Powerful-Strength Line-Reducing Concentrate formula to date.”


12.5% Vitamin C:

  • 10.5% Pure Vitamin C (L-Ascorbic Acid) When used as part of a topical skincare routine, this ingredient is known to contribute to helping diminish the appearance of fine lines and wrinkles while visibly improving skin’s radiance and texture2
  • 2% Vitamin Cg (Ascorbyl Glucoside) This ingredient is activated once it absorbs into the upper layers of the skin’s surface and is used in skincare products targeted to boost visible wrinkle reduction over time

In addition to being an essential vitamin in our diets and a prominent antioxidant, Vitamin C is an efficacious topical skincare ingredient.3 Our formula, with 12.5% Vitamin C, helps to provide the following benefits:

  • Anti-Aging: reduction of the appearance of fine lines and deep set wrinkles
  • Radiance: visible improvement of skin brightness
  • Skin texture boosting: visible and tactile improvement of skin’s surface quality.

Fragmented Hyaluronic Acid This fast-absorbing, small sized class of hyaluronic acid is famous for its ability to hold up to 1000 times its weight in water.4 Hyaluronic Acid acts like a sponge by drawing moisture in to skin’s surface layers and expanding as it absorbs and is commonly used in skincare products that are targeted to visibly reduce lines and refine skin texture.
