Kiehl’s, Powerful-Strength Vitamin C Serum, 75 ml, vitamin C face serum

This Kiehl’s face serum uses vitamin C as the main active substance, and its concentration is pretty high. Owing to this, the skin care product is good at reviving and brightening skin up. Also, when used regularly, Powerful-Strength Vitamin C Serum evens out skin tone and visibly improves complexion.

In addition, this face serum with vitamin C is expected to handle two tasks: reduce fine lines and improve skin appearance within a month. If vitamin C is applied regularly, the effects produced are highly satisfying since this essential nutrient is able to penetrate skin’s deeper surface layers and contribute to their regeneration. When it comes to the formula, apart from the already mentioned vitamin C concentrate, Kiehl’s face serum also contains hyaluronic acid that is responsible for replenishing skin with moisture and making it more supple. This dermatologist-tested cosmetic is safe for sensitive skin.
