Kiehl's Since 1851 Powerful Strength Line Reducing Concentrate

A serum with 12.5% Vitamin C that visibly reduces wrinkles. Now formulated with even more Vitamin C, Dermatologist Solutions™ Powerful-Strength Line-Reducing Concentrate is infused with 10.5% L-Ascorbic Acid and 2% Ascorbyl Glucoside.

The formula offers extensive skin benefits:

• Visibly reduces the appearance of fine lines and wrinkles, boosts skin radiance and improves texture
• Helps visibly minimize pores over time for smoother skin
• Infused with Hyaluronic Acid, our formula helps diminish the appearance of lines and wrinkles and improves skin texture
• Dermatologist-tested for safety
• Carefully-formulated for all skin types, even sensitive skin

Key Ingredients:

• ​Vitamin Cg - Vitamin Cg, or Ascorbyl Glucoside: A Vitamin C derivative that activates once absorbed into the upper layers of the skin’s surface. With antioxidant benefits, this form of Vitamin C is frequently used in anti-wrinkle skincare products to help reduce facial lines over time.
• Fragmented Hyaluronic Acid: This fast-absorbing form of Hyaluronic Acid is known for its ability to hold up to 1,000 times its weight in water. Acting like a sponge, it draws moisture into skin’s surface layers and expands as it absorbs. Hyaluronic Acid is known to help smooth and plump and is commonly used in skincare products intended to visibly reduce facial lines and refine texture.

How to Apply:

• STEP 1: Cleanse skin thoroughly prior to application
• STEP 2: Apply Vitamin C serum over entire face, avoiding the eye area
• STEP 3: As the formula blends into skin, you may experience a feeling of warmth
• TIP: Can be used twice a day, morning and night

The original Kiehl’s apothecary first served patrons in 1851, at the corner of 13th Street and Third Avenue in New York City.

In 1894, after honing his trade as an ambitious apprentice, pharmacist John Kiehl purchased the apothecary. John Kiehl & Co. began operations under “Kiehl Pharmacy.”

Mr. Irving Morse, John Kiehl’s apprentice, took over the business in 1921 and expanded the offerings to a full-service pharmacy, stocking teas, herbs, tinctures, honeys, and the first-ever Kiehl brand products, including the Original Musk Oil, our signature scent.

In 1924, Kiehl’s became one of the first companies to proudly list ingredients on its product labels — even before the U.S. government mandated it — to help customers make more informed and confident purchasing decisions.

Kiehl’s Pharmacy began introducing bold new products in 1962, such as Calendula Herbal-Extract Toner, Blue Astringent Lotion (loved by Andy Warhol), Kiehl’s Lip Balm #1, and Ultra Facial Moisturizer — all still among our best sellers today.

In 2006, Kiehl’s introduced Dermatologist SolutionsTM, a collection of advanced skincare formulated by Kiehl’s chemists (and developed in collaboration with an advisory panel of leading dermatologists) to address specific skin concerns.

Today, our nature-inspired, scientifically-proven formulas are powerful yet safe and help improve overall skin quality for visibly healthier-looking skin.
