The Benefits of Vitamin C in Skincare

From boosting radiance to helping diminish the signs of aging to antioxidant protection, Vitamin C is a highly efficacious skincare ingredient with a wide range of benefits. Skincare products with Vitamin C can offer something for pretty much everyone.

Topical Vitamin C products can make skin appear brighter and more even toned, fine lines less noticeable, and even help prevent premature aging. Because of its popularity, Vitamin C is used frequently in skincare products. It can be confusing to know what you should be using and how. Learn more about what Vitamin C can do for skin and how to choose the best Vitamin C products to use in your daily skincare routine.

Like any good skincare ingredient, Vitamin C is an overachiever. There are so many benefits to this molecule for skin’s appearance. From post-acne dark marks to fine lines, Vitamin C has got you covered.

What makes Vitamin C treatments so versatile are that L-Ascorbic Acid (the scientific name of the molecule) can function as both a preventative and reparative ingredient. Because of its antioxidant properties, it can help to protect your skin from dangerous free radicals, plus it has anti-aging benefits that make it a great ingredient to address the appearance of wrinkles less.

At Kiehl’s, we like to include Vitamin C in a wide variety of products, from eye creams to moisturizers to serums. In combination with other powerful ingredients, Vitamin C can have a visible impact on how your skin looks and feels.

To better help you understand just what L-Ascorbic Acid can do, we put together our list of the top Kiehl’s Vitamin C treatments for a range of skin issues. Below are the four most common problems that this multi-tasking molecule can help improve the appearance of.

Dark Spots

Photodamage and acne can lead to dark marks appearing on the skin’s surface. These are caused by an increase in melanin production to the affected areas. In our formulas, White Birch Extract and Vitamin C help to visibly correct dark spots over time.

Fine Lines & Wrinkles

Vitamin C’s ability to help protect the skin’s outermost layers from the free radical damage that can cause premature signs of aging, like fine lines and wrinkles, is one of its most powerful preventative benefits. When used with other key anti-aging and hydrating ingredients, Vitamin C can help minimize the look of fine lines and wrinkles over time.

Crow’s Feet

Vitamin C can also provide a noticeable difference for the fine lines around your eyes, a.k.a. crow’s feet. Vitamin C has been shown to help minimize the appearance of fine lines and wrinkles. In fact, with its brightening capabilities, it makes for a potent treatment to restore the appearance of youthful-looking eyes.
