Who is the Manufacturer of Kiehl’s Powerful-Strength 10% Vitamin C Eye Serum?

Many people are already aware of the company Kiehl’s because their products are sold in major department stores all across the country. The company started as a single pharmacy location in 1851.

They slowly grew to a national and international company and today, are one of the most sought-after skincare and beauty brands in the country. The company is said to have been founded by a man named John Kiehl.

How Does Kiehl’s Powerful-Strength 10% Vitamin C Eye Serums Work?

A lot of people have been using Kiehl’s Vitamin C Eye Serum specifically as an eye serum because many of the claimed effects have to do with the skin around the eyes. For instance, Kiehl’s is supposed to reduce puffiness under the eyes.

There are also claims that Kiehl’s Vitamin C Eye Serum will work to reduce the appearance of fine lines on the skin and prevent new ones from appearing. Some studies have validated some of these effects but not all claims are substantiated.

For instance, Kiehl’s Vitamin C Eye Serum is claimed to contain hyaluronic acid which may increase skin hydration; but only if there have been multiple molecule sizes of hyaluronic acid used in the formula which remains uncertain.

This supplement is designed to support skin hydration and elasticity from within, complementing topical treatments like vitamin C serums.

Kiehl’s Powerful-Strength 10% Vitamin C Eye Serum Key Ingredients in Kiehl’s Vitamin C Eye Serum

In the following section, we will discuss the possible effects of the Kiehl’s Vitamin C Eye Serum ingredients:

Hyaluronic Acid

Hyaluronic acid is a molecule that is known as a humectant – a substance that can attract and bind water to itself. So it’s supposed to be able to increase the hydration of the skin. However, there are different sizes of hyaluronic acid molecules. The larger molecules are effective for skin hydration but they don’t permeate the skin well because of their size.

So smaller hyaluronic acid molecules are also required to achieve the desired effect. There is no indication as to what size molecules of hyaluronic acid are contained in the Kiehl’s formula.

Vitamin C

Vitamin C is a natural antioxidant which means that it may be beneficial for minimizing the effects of oxidative stress on the skin. Oxidative stress can cause a myriad of blemishes including wrinkles, redness, and other kinds of irritation. For the most part, vitamin C application does not appear to be unsafe. However, the Harvard Health staff has stated the following about vitamin C for topical use:

While no serious side effects were reported with vitamin C use in any of these studies, it is important to note that there are only a handful of clinical trials that have studied the effects for vitamin C, and more studies are needed to confirm the findings presented here.

Tri-Peptide

Tri-peptide is a type of protein fragment that has been linked to increased collagen production and skin skin resilience. Tripeptide has been claimed by some authorities to be essential for skin health as it seems to have an effect on the very structure of the skin itself. The National Institutes of Health has stated that:

The present study showed improvements in facial wrinkles, skin elasticity, and density without any adverse effects after use of the topical CTP (Collagen Tripeptide).

Skin Protection – It’s possible that the vitamin C content of the Kiehl’s Vitamin C Eye Serum formula may help protect the skin against common signs of sun damage which can include dark spots, hyperpigmentation, and fine lines.*
