Reviews mention

  • Weightless, blurring complexion finishes
  • Creamy, brightening concealer formula
  • Natural‑looking, defining brow products
  • Hydrating, glossy lip oils
  • Occasional concealer creasing under eyes
  • Inconsistent, yellow‑leaning shade undertones
  • Clumpy, flaky mascara texture
  • Premature formula separation and odor

Kosas earns strong reviews for delivering natural, skin‑improving makeup that works—standouts like Revealer Concealer and Cloud Set powder blur, brighten, and wear weightlessly—while Air Brow and Wet Lip Oil draw repeat loyalty. Reviews also flag drawbacks: occasional creasing or dryness with concealer, overly yellow undertones for some complexions, clumpy mascara, glowy finishes that can run oily, and reports of products separating or smelling “off” over time.

  • For years, I’ve struggled with concealers creasing by midday, sometimes even an hour after application. The foundation is incredibly light, making it feel like I’m wearing no makeup at all. There was no settling into pores and the foundation stayed in place, flawless all day. The brightening powder did not amplify dry areas and gave me a subtle glow I am so impressed with the quality of products, I’ve finally found my holy grail, must have makeup.

  • I have switched to using other brands for makeup bug always comeback to a couple of tried and true kosas products. Maybe its partially cause I love the clear pink but they carry my go to eyebrow pencil. I recently purchased a bronzer but I am still not 100% sold on if I will be buying it again.

  • I feel like EVERY makeup video mentions Kosas as their holy grail concealer — so obviously, I had to try it for myself! I was already a fan of the brand (their wet lip oil in Unbuttoned is PERFECTION), so I went in with pretty high expectations. And honestly, their product met every one of them! The concealer blends beautifully, and provides so much coverage without being cakey or too thick. It’s natural, light, and a dream to apply. I get the hype!

  • I decided to try Kosas because it’s known for being a cleaner beauty brand with skincare benefits built in. My skin can be pretty reactive, and I had no issues with any of the products I tried, which was a big plus. I don’t usually wear foundation (or much makeup in general), but I liked that the Revealer Skin-Improving Foundation felt lightweight and didn’t get cakey like a lot of formulas do on me. My skin did feel a little dry by the end of the day, but that’s pretty typical for me with any foundation. I was kind of neutral on the mascara—it wasn’t bad, but not my favorite and did feel a bit clumpy at times. That said, I’m really impressed with the Tinted Air Brow. I’ve tried a ton of brow tints since the ends of my brows are much lighter, and this one really stood out. I’ve also been using other brow growth serums at the same time, but I do feel like my brows have filled in more, and the tint subtly darkened the lighter hairs, which is a huge win. Definitely worth trying, especially if you’re picky about brow products.

  • This Sun Show Moisturizing Baked Bronzer is so beautiful, it gives a sun-kissed glow and looks lovely. It is lightweight and applies very nicely, I get compliments on how natural my face looks but also has some color!

  • Kosas is a trend‑forward makeup and skincare‑meets‑beauty brand that focuses on “makeup for skincare freaks” — products that look good and feel good on the skin. The formulas are dermatologist‑tested and made without many controversial ingredients, aligning with a clean beauty ethos while still delivering performance. What most people love about Kosas is how lightweight and natural the products feel — items like Kosas Revealer Super Creamy Brightening Concealer blend seamlessly with skin and many of their color

  • I've used AHA serum deodorants for years and I've never found a better one than Kosas. I always come back to it for the ease of application, the clean scent, and the value of the bottle. It's also aluminum free which is a deodorant requirement for me. $18 is a little steep but I truly feel that I get a lot out of each of these tubes - they last me many months. I apply at night once I'm dried off after showering, then will apply a different more scented deodorant in the morning (also aluminum free). I feel that the Kosas is an essential first step to start working overnight and kill bacteria before it even starts smelling, which then sets up my morning application of a different deodorant for success.

  • I really loved my Kosas products. More than skincare, I prioritize skincare so that I can be less maintenance with my makeup routine, so I especially like that Kosas incorporates skincare into its cosmetic products. Moreover, the quality and performance of the products are fantastic! They're lightweight but very durable and effective and feel such high quality on my skin. For example, I've really been enjoying my Kosas lip gloss, it feels like nothing, hydrates my lips, but also makes my lip pop in a natural way.

  • Kosas makes excellent products. Their tinted air-brow is my holy grail item, much better than brow gels from similar brands that I've tried. Their products are all cruelty free and great for sensitive skin. The Chemistry AHA serum deodorant is the only aluminum free kind I've found that works for me. I ordered their "bright eyes" set and love the two concealers, they have good coverage without a heavy feeling. The extra makeup blender is a plus- all their products are easy to apply without specialty tools, but the blender is fun to use. Overall I'm really happy with my order, they even thew in a free compact mirror.

  • This is my absolute favorite tinted brow gel. The shade selection is great, and the gel makes my brows look defined yet natural. It also does a great job of keeping them in place throughout the day. It does not flake. Will continue to repurchase.

  • The shade selection was great in my opinion and I was able to find a shade that worked well for my skin tone. I did really enjoy this concealer but at times, I feel like it was a little drying or it would look a bit creased under my eyes.

  • Before purchasing the Kosas Revealer Skin-Improving Foundation, I had been using the same Tarte foundation for a decade. When I ran out, I decided to try something new with these criteria: clean-er/ish formulation, makes me look dewy and adds moisture, affordable, contains SPF, buildable coverage. I tried a few (one from Saie) but once I tried Revealer, nothing else compared. I'm not a big foundation-wearer (or even makeup wearer), but I do have uneven skin tone and some redness and wanted to have something that felt light and left my complexion looking markedly improved. What makes it stand out: it delivers on all my criteria and then some. I even blend like a quarter pump with my daily SPF lotion (currently using La Roche-Posay Anthelios Face 60 SPF) and apply them at the same time. I cannot explain how easy it is to apply just with fingers. Without any other product, I'm 70% done. TLDR: No notes.

  • The Kosas Cloud Set Mist is a dream for sensitive skin — no irritation, no harsh ingredients, just clean beauty that actually performs. A few spritzes and my makeup is locked in all day and night without ever feeling heavy or cakey. It’s genuinely the easiest step in my routine — point, spritz, go. My skin looks smoother and more airbrushed without any effort. Clean, effortless, and it lasts forever? Yeah, this one’s a keeper.

  • The Kosas Revealer Concealer is my absolute holy grail — I’ve tried countless concealers and nothing comes close. It blurs, brightens, and actually improves my skin over time thanks to the peptides and caffeine. It feels weightless but gives real coverage, never creases, and somehow looks better as the day goes on. I wear it under my eyes, on blemishes, everywhere. Friends always ask what I’m doing differently — it’s this. If you’re on the fence, just get it. You won’t go back.

  • This is the product that helped me finally committed to daily sunscreen after resisting for years due to hating the sticky, tacky, white-cast standard SPF in the US. I love the subtle glow of the Golden Glow shade, which I find to be just enough subtle color to go without foundation most days. It is definitely a glowy finish, which is something to be mindful of if you prefer a more matte look, but absorbs really nicely and also provides a great base for makeup on the days I do go for a more coverage look.

  • I was on the hunt for a new bronzer, and I stumbled upon the Kosas one, and it was EXACTLY WHAT I WAS LOOKING FOR!! The formula is very nice and easy to apply. It adds a beautiful, natural, but slightly shimmery tan to my skin.

  • I have tried SO many concealers and this is one is by far the best and the one that I just keep coming back to. It has the perfect coverage and weight, the shade options make it really easy to find one that works, and it's gentle on my sensitive, eczema-prone skin!

  • I bought the brightening shade buttery and LOVE IT. I use it almost every day, both for no make up and full make up looks. It's such a great multi-purpose product. Also, as a pale olive skin girl it's really hard to find products that don't look too white/pink or too orange. The yellow in this makes all the product underneath look like the perfect shade for me. Highly recommend!!

  • Very hydrating! Like the slight hint of color and the benefits that come from it. Color can sometimes be draining on the lips and you have to choose between treat vs look, it is nice to have 1 product that can do both.

  • The best deodorant! I've been using it non stop for the past 2 years. Great with the sweating and lightens my underarms. Love how it's a clean product as well!
