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.

  • Cute packaging and great products. They're vegan and the creamy concealer works really well.

    Feedback

    The packaging of the concealer can make the product go all over and a little messy when you're not careful.

  • Kosas can take all my money. All of their products have been fantastic, and have wonderfully natural finishes. It's definitely an upgrade to someone who has used Glossier for a long time, but wanted longer staying, cleaner products. I would highly recommend Kosas and their products.

    Wish they had more color options for more inclusive skin tones.

  • Like many, I’ve tried what feels like a million natural deodorants…. Their deodorant is one of the only brands I actually like and continue to use. When it’s high stakes I do tend to break out the Secret gel, but most days I’m using this. It applies super easily (it’s a liquid in a rollerball, so it’s not pasty like other natural deodorants). Love and will continue to repurchase.

  • I've been using Kosas Chemistry AHA Serum Deodorant for about 3 months now. I purchased it because I wanted an aluminum free deodorant that has an easier application. Although it doesn't stop you from sweating, it seems to work in terms of odour control. It also dries relatively quickly.

  • I love love love Kosas they have a good shade range for skin tones but also a wide range of products. I would say they are on the more natural side of makeup they remind me of Glossier with branding and audience. But I have used their air brow gel and I am absolutely in love and dont use anything else at the moment.

  • Everything I’ve tried from this brand was terrible. O don’t know how they’re so popular. Shocked

  • Got their face powder to keep me from ~glistening~ in the summer humidity. Works amazingly, lasts from morning to night.

  • I've been using the Revealer Concealer in shade 2.5 for almost a year now and it is my favorite concealer! I use it for light make up days and more coverage days. I really love that its a clean product and since I use it mostly under my eyes, I do not have to worry about any ingredients or scents irritating my eyes. Its creamy and has great, buildable coverage. I use a setting powder and there is still minimal creasing but it is not very noticeable. I also started using the Revealer Skin-Improving Foundation with SPF25 in shade 180 for about six months. Its medium coverage which is my preferred type of coverage. I wear an SPF regularly so the added SPF in this is not that important to me. There is creasing at my smile lines, so I try to set that area very well. Both products have lasted longer than I expected them to for how frequently I use them!

    I have golden undertones but the shades for golden undertones are too yellow for my skin, so I actually use the shades that have cool undertones. If someone has naturally cool undertones, they might find all of the shades to be too yellow for their skin. There is also some creasing for both the foundation and concealer.

  • One win, one loss. Best deodorant! Love the deodorant for sports and just everyday! Concealer was not my favorite, nice formula, but I just could not get it to blend out nice. Could be a me problem.

  • I LOVE the skin-improving foundation serum. It goes on so easily, and adds such a nice glow (granted, it can be a little too much if you don't set it with powder, unless you reallyyy want that dewy look). I also like that they seem to have more yellow undertones which works really well for my skin tone-- a lot of other brands tend to be too orange/pink.

    Feedback

    Maybe slightly less glow so you don't have to set it, but I still love it!

  • The Kosas concealer is a lightweight product and has a wide variety of shades!! I love their inclusivity

  • The best concealer- no need for foundation. Their lip gloss in unzipped is my ultimate daily go to. Bronzer, setting powder are both phenomenal. Brow gel is amazing. Can’t say enough good things about these products!

  • I’ve had a great experience overall with the brand. I love their packaging and branding. I think the tinted face oil is excellent, a little goes a long way and it leaves you with a more evened out tone and a radiant finish. It holds up when putting other makeup over it. I also love the concealer! It has great coverage but feels light. The Wet lip oils are my favorite product from the brand.

    Feedback

    The only thing I dislike is that it seems that the cream products like foundation, concealer, face oil tend to go “off” before the shelf life printed on the packaging. After just a couple of weeks of having them they sometimes begin to separate and smell off. You don’t get to use the entire thing before it prematurely expires yet you’re paying quite a bit for the product. I thought it may have been a one off thing but it’s happened to me on three separate occasions.

  • Looking for a concealer for my dry under eyes I came across their product. This stuff if amazing. It does take a little trial and error to find a color as the ones recommended by their color matching quiz were too dark but once I found my match this stuff is my ride or die.

  • I have the Kosas concealer. It's very creamer and applies really well. I like that it doesn't dry out my under eyes. I don't notice any creasing either. I really like the product!

  • I have their full coverage concealer stick. As someone that has oily skin in my t-zone area, this provides a beautiful shining touch without drying out my skin. I can use it full coverage with a very small amount. I don't need too much of it which is great because it lasts a longer time and saves me some money.

    affordable. perfect for gifts.

  • The take-home kit is SO good. It comes with samples of all their hits, the sizes for some of which (concealer, lip tint, and eyebrow gel) are SUBSTANTIAL...like you can get 4-5 uses out of every shade, and they give you a solid selection to try out. It also comes with two deluxe sample tubes of their clean mascara and clear brow gel. And the best part is you get the amount you spend on the sample kit back in credit to use to purchase any full-size items from the website.

    If you're considering trying this brand, the take-home kit is really the way to go!

  • Love this brand so much!! Their concealer is so good at covering dark circles and they have so many shades

  • Love the Kosas highlighter. It makes me skin look hydrated and really healthy.

  • I've used Kosas for a couple of years. I like the concealer. I use it under my eye. The color blends well with my skin, thus not requiring a lot of blending. I can go out with just the concealer in place, if needed. My new favorite project is the Plum & Juicy spray. It provides a nice finish to the skin. I've gone out more than once without makeup because the spray gave me freshness and a glow. So, I do not need to use makeup to get that look. I often use it in the evening because it feels good on the skin. I love the bottle it has a beautiful luxe feel to it.
