Brand Overview

Kiehl’s Powerful Strength Line-Reducing & Dark Circle-Diminishing Vitamin C Eye Serum contains 10% vitamin C (ascorbic acid) in a waterless, ultra-silky cream that has strong potential to visibly lighten dark circles due to sun damage. Of course, a 10% concentration of vitamin C also brings firming and line-smoothing benefits!

The fragrance-free formula for all skin types is packaged in an interesting manner: an opaque, cylindrical container is “double-walled”, meaning it’s placed inside a translucent brown bottle. Since the inner component that holds the product is opaque, light exposure isn’t an issue. And that’s great, because vitamin C is highly susceptible to breaking down with daily exposure to the elements.

More on the packaging: the bottle is topped with a smooth-action pump (dispensing this just feels more elegant compared to many other pumps), making it very easy to control how much you use.

In use, whether you dab or blend this across the undereye area, it goes on smoothly minus any pilling, and it layers well with other products. We tried this over and under various serums, eye creams, and moisturizers and never had an issue. As a bonus, the silicone-enhanced texture makes fine lines and wrinkles instantly look less apparent; in fact, our fine lines were “filled in” and this smoothness remained for hours.

Along with 10% vitamin C, eye-area skin is also treated to the cell-communicating adenosine, the anti-wrinkle amino acid lysine, hyaluronic acid, and a blend of anti-aging peptides. All told, it’s a very good mix that keeps this from being a one-note vitamin C treatment.

The sole drawback is the buffering ingredient hydroxyethylpiperazine ethane sulfonic acid, also known as HEPES. Though there isn’t any direct research showing it hurts skin, some studies show it can generate free-radical damage in the presence of oxygen. The high amount of vitamin C this serum contains likely counters this, but if you decide to try it, make sure all of your leave-on skin care products contain a robust mix of antioxidants.

Despite our obvious enthusiasm for this product, we have to say that not everyone needs a special serum for the eye area (see More Info). For example, if you’re already using a high-strength, well formulated vitamin C product on your face, it’s perfectly fine to also apply this around your eyes. But if you feel your eye area needs some special attention, particularly for sun-induced dark circles, this offering from Kiehl’s is ready to help!

Pros:
  • Contains an amount of vitamin C likely to fade dark circles from sun damage.
  • Silky, line-smoothing gel-cream texture instantly makes eye area look younger.
  • Packaged to keep the vitamin C stable during use.
  • Layers well with other products.
  • Fragrance and irritant free.
Cons:
  • None.

Why You May Not Need an Eye Serum: There’s much you can do to address signs of aging around your eyes, but it’s not mandatory to use a product that’s marketed specifically for the eye area. Any product loaded with antioxidants, emollients, skin-repairing and skin-brightening agents, and skin-soothing ingredients will also work well in the eye area. Those ingredients don’t have to come in a product labeled eye serum—they can be present in any well-formulated facial moisturizer or serum.

Most of the products designated as exclusively for the eye area are not really necessary because they contain nothing special for the eye area, they come in packaging that will not maintain the effectiveness of their key ingredients, and/or they are poorly formulated with fragrance or other irritants.

Just because a product is labeled as a special eye-area treatment does not mean it’s good for the eye area, or for any part of the face; in fact, many can make matters worse.

It’s staggering how many eye-area products lack even the most basic ingredients to help skin. For example, most don’t contain sunscreen, which is a serious problem because it leaves skin around your eyes vulnerable to sun damage—and that absolutely will make dark circles, puffiness, and wrinkles worse. Of course, for nighttime use, eye-area products without sun protection are just fine. If you opt to apply an eye cream without sunscreen during the day, be sure to apply a sunscreen rated SPF 30 or greater over it.

Any product you use in the eye area must be well formulated and appropriate for the skin type around your eyes. You might prefer to use a product specially labeled as an eye cream, but you might do just as well by applying your regular facial moisturizer and/or serum around your eyes. Experiment to see what combination of products gives you the best results.

Kiehl's At-A-Glance

Kiehls has been around for quite some time, with its origins in a New York City-based pharmacy established in 1851. The brand is perhaps best known for its apothecary-style packaging and its best-selling (and celebrity favorite) Lip Balm #1.

Though the brand claims its products are made with the finest naturally-derived ingredients, most of its formulations include synthetically-produced ingredients as well. Like most skincare companies the line contains both good and not-so-great offerings; Kiehls main misstep is that many of its products contain fragrance ingredients that could irritate skin, particularly sensitive skin.

Note: Kiehl's is categorized as a brand that tests on animals because its products are sold in China. Although Kiehl's does not conduct animal testing for its products sold elsewhere, the Chinese government requires imported cosmetics be tested on animals, so foreign companies retailing there must comply. This requirement is why some brands state that they dont test on animals unless required by law. Animal rights organizations consider cosmetic companies retailed in China to be brands that test on animals, and so does the Beautypedia Research Team.
