Revealer Super Creamy + Brightening Concealer
Kosas’ Revealer Super Creamy + Brightening Concealer excels in some ways but falls short in others, leading us to a somewhat mixed review.
On the positive side, the liquidy-cream consistency works well around the eye area, where it’s substantial enough to offer long-lasting coverage, while resisting creasing and settling into fine lines. It strikes a nice balance that doesn’t leave skin looking parched or cakey, nor is it so emollient that it slips, slides and fades away.
As the its name implies, the natural finish is ever-so-slightly brightening with an ultra-subtle sheen (it’s not overtly noticeable but it’s there if you look closely). This wouldn’t be our top pick to cover imperfections like a pimple, but it can be used for such in a pinch.
Ignore KOSAS’ claim that this doubles as an eye cream. It’s not hydrating enough to qualify for that and although it contains some good ingredients, it also contains some iffy ones. Case in point, the arnica extract that KOSAS touts as being “healing” can actually be sensitizing to skin. Granted, the concentration is here is low enough to minimize that concern, but it’s coupled with another ingredient known to be irritating to skin, fennel oil. Simply put, the formula would be better off without these ingredients (see More Info to learn why you don’t have to see or feel irritation for it to be happening).
We must also point out that it can be a challenge to find the right shade (especially when ordering online) because the descriptors and swatches depicted don’t always match up to reality. For example, the 03 shade is billed as “fair light with cool undertones” but leans on the yellow end of the color spectrum.
We noticed a handful of customer reviews mentioning similar issues—although there are also plenty that mention finding a perfect match (if you’ve tried this concealer share your experience in the Community Reviews section). At the time of this review, there are 16 colors to choose from ranging from porcelain to deep.
Shades aside, were it not for the irritants we’d be happy to recommend Revealer Super Creamy + Brightening Concealer for the way it delivers lasting coverage in a natural looking way. With a couple tweaks this could easily be a top contending concealer.
- Provides lasting coverage that looks natural (not cakey).
- Resists creasing/settling into fine lines.
- Ever-so-slightly brightening with an ultra-subtle sheen, ideal for eye area.
- Contains known irritants.
- Can be a challenge to find the right shade.
Irritating Ingredients: We cannot stress this enough: Sensitizing, harsh, abrasive, and/or fragrant ingredients are bad for all skin types. Daily application of skincare products that contain these irritating ingredients is a major way we unwittingly do our skin a disservice.
Irritating ingredients are a problem because they can lead to visible problems, such as redness, rough skin, dull skin, dryness, increased oil production, and clogged pores, and they contribute to making signs of aging worse.
Switching to non-irritating, gentle skincare products can make all the difference in the world. Non-irritating products are those packed with beneficial ingredients that also replenish and soothe skin, without any volatile ingredients, such as those present in fragrance ingredients, whether natural or synthetic.
A surprising fact: Research has demonstrated that you do not need to see or feel the effects of irritants on your skin for it to be suffering, and visible damage may not become apparent for a long time. Don’t get lulled into thinking that if you don’t see or feel signs of irritation, everything is OK.
Generally, it’s best to eliminate, or minimize as much as possible, your exposure to ingredients that are known to irritate skin. There are many completely non-irritating products that contain effective ingredients, so there’s no reason to put your skin at risk with products that include ingredients research has shown can be a problem.

Launched in 2015, Kosas prides itself as a no-fuss makeup line infused with beneficial ingredients. The brand’s founder, Sheena Yaites, says the name Kosas was inspired by the philosophy of the five “kosas” of self: “A physical layer, a vitalizing layer of energy, a sensory mental layer, a discerning intellectual layer, and a layer of truthful bliss.” As she puts it, “Beauty lives in each of these layers, not just in the physical.”
The brand leans heavily into a clean beauty focus, which as they claim utilizes, “the best of molecular biology to create better products that are not only safe and non-toxic, but truly effective and beneficial too.”
While we applaud the concepting behind producing safe, effective products, Kosas tends to veer off course by formulating with fragrant botanicals that haven been proven to irritate skin. On the other hand, they also use some great antioxidants and replenishing ingredients, so it’s truly a mix of good and bad.
While some formulas fare better than others, the actual aesthetics and performance of the makeup tends to live up to the hype, and Kosas’ ethos of “effortlessly applied, flattering across skin tones” products reigns true for the most part.
All in all, Kosas is one of those lines that leaves us with mixed feelings. Judging simply by looks, it’s great. But a deeper dive into the formulas can be disappointing at times.
