Vitamin C FAQ

How does Vitamin C help your skin?

Vitamin C, the skincare super ingredient. When ingested orally it acts as an immune booster and when applied topically it shows it's true strengths. Vitamin C skincare serums serve multiple roles surrounding the protection and production of your collagen. It protects and preserves as Vitamin C is a powerful antioxidant which reduces oxidation and forms of hyperpigmentation caused by environmental stress on the skin.

These environmental stressors come in the form of harsh free radicals caused by air pollutants, sun damage and stress. Vitamin C helps the body shut down these toxic molecules and as a result reduces the aging signs left behind by the accumulated free radicals. Vitamin C does more than combat everyday free radicals, prevent brown spots and reduce inflammation from acne, but it also helps to fade your existing skincare concerns as well.

Vitamin C Skincare builds as much as it preserves by enhancing the production of the collagen protein. Collagen is a key component in reducing the signs of aging, acne scars, dull skin and wrinkles. Vitamin C will not only help your skin deal with today and tomorrow, but it will also help clear up its past.

Does Vitamin C help acne?

As Vitamin C becomes more broadly used for more than just oral consumption, we learn more about it's powerful effects when applied topically. Acne, derived from environmental stress and clogged pores from excess sebum, will be reduced as Vitamin C helps reduce inflammation, scarring and discoloration.

Vitamin C, when applied directly to the skin, promotes collagen synthesis, inhibits melanin production, and scavenges free radicals. These factors contribute to restoring and brightening damaged skin as a result of an acne breakout. Using Vitamin C to help increase the protective army of collagen protein on your face will help battle the pollution based acne you face everyday while improving skin texture and reducing the scars from any battles prior.

Does Vitamin C lighten your skin?

Vitamin C acts in many ways to help reduce dark spots and other forms of hyperpigmentation. More specifically, this super ingredient helps to treat skin pigmentation, acne blemishes, age spots, skin discoloration and blotchiness. Vitamin C acts preventatively through its antioxidant properties and can reduce the harsh rays your skin is forced to deal with when enjoying the sunshine!

On its own, Vitamin C will work to lighten your skin. However, the improvements are drastic when Vitamin C serums are introduced with other key ingredients such as hyaluronic acid. With the combined anti-aging benefits of Hyaluronic Acid and the collagen growth inducing powers of Vitamin C, Kiehl's Vitamin C Serums rank among the best for skincare.

Which form of Vitamin C is best for skin?

Vitamin C can be delivered to your body in two ways: orally and topically. The benefits for either methods of delivery are unmatched. From immune boosting to lowering cholesterol and combating stress, ingesting Vitamin C remains dominant as a super ingredient.

Here at Kiehl's, we have tapped into that super ingredient and created a Vitamin C serum. This serum has allowed us to maximize the skincare benefits of Vitamin C by combining key ingredients such as Hyaluronic Acid with it. That being said, the form of Vitamin C which is best absorbed by the skin topically is the chemically active form called L-ascorbic acid. This chemically active substance is what makes the topical application of Vitamin C Serums that much more effective for skincare concerns than ingesting orally.

It is important to note that while this is an active ingredient, it is most effective when fresh and loses it potency. Vitamin C serums are also reactive to sunlight and for that reason Kiehl's packages them in tinted bottles. Make sure to store them in dark and cool places for the best results.
