  • Weightless, blurring complexion finishes
  • Creamy, brightening concealer formula

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.

  • 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!

  • 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

  • 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 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.

  • 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 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!

  • I was really happy with most of the products I ordered from Kosas! Shipping was a little slow, but since it was free/low cost, I didn’t mind too much. Everything arrived in cute, minimal packaging, which I appreciated. I picked up the Revealer Concealer and absolutely love it. The coverage is great while still being creamy and glowy—perfect for the under-eye. My only note is that it does have a noticeable fragrance, so it may not be ideal for anyone with sensitive skin. I also tried the baked bronzer. The shade is beautiful and super buildable, but it’s more shimmery than it looked in the photos, which I'm not sure if I like yet. The standout for me was the gel eyeliner. I’m obsessed! It's smooth, easy to apply, and doesn’t transfer at all. Lastly, I bought the LipFuel Lip Balm. It feels nice on the lips and the cool pink shade is gorgeous, but I found that it didn't actually help with dryness at all, so it’s more of a cosmetic balm than a healing one. Overall, the quality is great across the board, with just a few small drawbacks. I’d 100% repurchase the concealer and the eyeliner.

  • Some of the products I find don’t work the best for me ( like the clear brow gel), but the brow pencil is fantastic. I really love the packaging design of all their products so I continue to buy and see what works for me.

  • As a male, I don't like to wear a lot of makeup but sometimes it is nice to have your skin looking a little extra fresh, especially when you have a little redness or oiliness. I found that the Cloud Setting Powder is great for that. It's really subtle and feels really clean on my skin. My skin doesn't break out afterwards. I use their powder brush which is fine. I don't really know much about brushes but it seems to be good. Then I've been using the brow pencil to just fill in my eyebrows a little bit, make them a little darker and more shaped. I tried to use it a little bit as like a kind of eyeliner to darken my lashes since they're blonde. Not sure how much effect it has but overall really happy seems to be a really good clean product

  • I love the eyebrow pencil. It’s very easy to make fine eyebrow like strokes to fill in any sparse areas of the brow without it looking too dark or cakey. I’ve been loyal to the same setting spray for 5 years now but I was pleasantly surprised by the kosas spray. The cloud set spray definitely helped the layers of my makeup melt together and stay put even while being out in the cold for hours with a runny nose. The concealer in 0.5 very light w/ neutral undertones was way too dark and yellow for me but thankfully the exchange process was very easy and painless and the replacement arrived quickly. I ended up replacing it with 0.7 very light w/ cool pink undertones which is still not my perfect shade match but might be usable in the summer. The formula of the concealer is fantastic and I love the skincare ingredients. If they come out with a wider shade range in their complexion products I would definitely try more.

  • The revealer concealer and cloud set powders are two of my favorites in their category! It took me a few tries in Sephora to find the shade I liked in the revealer but I’ve been buying online ever since. I appreciate the options in undertones to make sure it blends well! The powder is so light and doesn’t weigh down my skin, which I love as well! I haven’t tried other products but continue to buy these two.

  • 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.

  • The cloud set powder is easily my favorite face powder ever! It sets undereye concealer so smoothly and prevents creasing through the day. It is seriously the best undereye setting powder (and trust me, i've tried so many) The formula really is so smoothing that I've been complimented on my skin + stopped on the street multiple times! I'm on my third compact now, and I recommend it to everyone.

  • Revealer Extra Bright - Illusion Brightens and hydrates under-eyes without heaviness. Smooths fine lines and lifts subtly, though I still layer concealer for full coverage. Works best on mature or texture-prone skin. Lightweight, skin-friendly, and gives a naturally awake look. Revealer Concealer - Tone 3.8 N Creamy, buildable coverage that looks natural and luminous. Blends easily over or under makeup, keeping under-eyes fresh and hydrated. Slight setting needed to prevent minor creasing. Great for mature skin and anyone seeking a clean, polished everyday concealer.

  • Pleasantly surprised with these! I love the way it feels on my skin, and knowing that it's actually got benefits for my skin and won't leave me breaking out. I'm not a huge makeup person and weird about textures, and this feels like a win for me. It hides spots well, without looking cakey or anything like that. And their color matching/support is spot on. No pun intended. The one thing is I wish the packaging was more cohesive. The foundation looks great and premium with the yellow caps, but then the mascara is shiny and purple, the spray serum has blue type on a pink bottle, etc. This is absolutely not something most people care about it but it'd look so much better as a set if it matched better.
