Kiehl's Powerful Strength Line Reducing Concentrate is a vitamin C serum formulated with 12.5% vitamin C and hyaluronic acid. This serum was found to boost radiance and smooths skin texture to help visibly minimize the appearance of enlarged pores. 

According to Kiehl's, this product visibly reduces lines and wrinkles in 2 weeks, while helping firm skin over time. Additionally, the stabilized vitamin C penetrates the skin's deeper surface layers and remains effective in the skin for up to 6 days.

Key Ingredients include:

  • Vitamin C: L-ascorbic acid is an efficacious antioxidant known for its ability to improve the appearance of skin aging.
  • Vitamin Cg: Ascorbyl glucoside, a vitamin C derivative that activates once absorbed into the upper layers of the skin's surface. With antioxidant benefits, it is frequently used in anti-wrinkle skin care products to help reduce facial lines over time.
  • Fragmented hyaluronic acid: This fast-absorbing form of hyaluronic acid acts like a sponge and draws moisture into the skin's surface layers and expands as it absorbs. Hyaluronic acid is known to help smooth and plump, and is commonly used in skin care products to visibly reduce facial lines and refine texture.

Ingredients:  Propylene Glycol, Dimethicone, Glycerin, Ascorbic Acid, Ethylhexyl Palmitate, Cetyl Peg/Ppg-10/1 Dimethicone, Dimethicone Crosspolymer, Ascorbyl Glucoside, Cyclohexasiloxane, Hydroxyethylpiperazine Ethane Sulfonic Acid, Lauroyl Lysine, Acrylonitrile/Methyl Methacrylate/ Vinylidene Chloride Copolymer, Polysilicone-11, Adenosine, Hydrolyzed Hyaluronic Acid, Limonene, Isobutane, Citrus Aurantium Dulcis (Orange) Peel Oil, Citrus Limon Peel Oil/Lemon Peel Oil, Citral, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate.
