Tinted Face Oil Foundation
KOSAS Tinted Face Oil Foundation offers lightweight coverage with a smooth glide. The problem is that unless your skin type is smack dab in the perfectly normal range (as opposed to showing any signs of dryness or oiliness), there will be issues that lead to it not wearing well, greatly limiting the audience who can use it.
Housed in an opaque plastic bottle and dispensed via needle-nose tip, you’re instructed to shake Tinted Face Oil before application to mix the pigment and oil. After doing so, it spreads effortlessly across skin, offering sheer, ‘you-but-better’ type of coverage that helps even out skin tone. Because the shades are sheer, they’re adaptable across a wide variety of fair to deep skin tones.
The assortment of oils, silicone, and kaolin (an absorbent ingredient) are an interesting mix with this tinted formula, but there are some opposing forces that make it tricky to work with. While the non-fragrant, antioxidant-rich oils (including jojoba, avocado, and meadowfoam) would normally be great for dry skin, the way they’re combined with the drier finish ingredients + pigments results in the formula highlighting any sort of dryness or flaky patches.
On the other hand, it’s not a slam dunk for oily skin either, as the coverage tends to break down and separate in oily areas, which leaves skin looking overly shiny.
The brand also cautions that applying Tinted Face Oil Foundation over “serums or skincare containing silicones may cause pilling,” and we found that to be 100% true.
Because of all the nuances, we’re giving Tinted Face Oil Foundation just a so-so rating, but if you’re one of the lucky few to have perfectly “normal” skin without any of the issues mentioned above, Tinted Face Oil Foundation can look great, offering breathable, natural coverage. The performance really comes down to your skin type with this one!
Note: The rosemary extract this contains may have a fragrant component depending on which part of the plant was used and how it was extracted. However, we could not detect its scent and as such are not concerned about its potential to irritate skin in this form.

With application that takes as little as 10 seconds, imperceptible all-day wear, and true nourishment, Tinted Face Oil Foundation is the new definition of the flawless face. The breathable, silky-clean formula evens the look of skin tone, minimizes pores, and erases imperfections, while supporting the health of the skin underneath. Shake well—the pigment and oil have to emulsify before application so you receive the perfect amount of both. The formula doesn’t contain silicone, so it works best on exfoliated skin. Layer over moisturizer or sunscreen to allow skincare to soak in before applying. Serums or skincare containing silicones may cause pilling.
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.
