The best foundation!!!
Style: Refill, Color: Golden Glow
10/10 powder foundation. If you’re on the fence, just do it. I have used this product since 2014 and haven’t ever bothered to try and find anything better. There’s simply no need. I’ve used the color Golden Glow almost every time, and it has always managed to match my skin throughout all the seasons. It is lightweight but full coverage. It’s magic. I mostly wear this on its own, with just moisturizer as a base. It’s so easy to apply with a large brush, and run out the door feeling like you have a full face of makeup on. It does pair beautifully with my liquid foundation for when I’m looking for maximum coverage. The price point is fair in my opinion. Each refill last me about 6 months. You do have to purchase the compact case which is an addition $25 but that’s a one time fee. I have never been happier or purchased a skincare product more frequently than this one. You seriously won’t regret it.

Flawless Full Coverage
Style: Refill, Color: Warm Silk
My absolute FAVORITE foundation for anyone with extremely oily skin. Honestly, this foundation is great for all skin types. The clean ingredients are a huge plus. I have tried every oil control makeup combination possible over the past two plus decades that I’ve worn makeup. I can’t get over how amazingly flawless and silky smooth this product makes my skin look. It’s lightweight yet 100% full coverage foundation. I live in the most humid climate possible and appreciate the fact that I’m not having to reapply more powder anytime I step outside for more than five minutes. After using this powder for the last few years I realized that I needed to make a change in my products and have slowly started purchasing more and more Jane Iredale products. I cannot recommend this powder foundation enough for anyone who has oily skin and wants a full coverage foundation that looks and feels natural!!!

Simplicity
Style: Refill, Color: Golden Glow, Style: Refill, Color: Golden Glow
All time favorite powder of 15 years 🫶 doesn't clog pores, stays on well all day, and is smooth to apply. A little goes a long way with a moisturizer and toner. Hope to see the pad applicators included in the refills in the near future, I used a teardrop sponge that worked great to cover pores and even tone. I didn't cover my cheek bones to allow natural pigment. Thanks for the wonderful quality over the years 🤗

Wonderful mineral powder foundation
Style: Refill, Color: Warm Sienna, Style: Refill, Color: Warm Sienna
Wow this powder foundation blew all the other powder foundations I’ve tried out of the water. I have this strong yellow undertone to my skin and always struggle, I purchased warm sienna and by all means it’s not dark at all. This foundation leaves a soft natural glow that makes my skin look natural yet covers imperfections very well. It also feels light weight on my skin and lasts 8 hours before it starts to break down with my oily skin but the Danessa Myricks yummy skin blurring balm powder that I use as a primer in universal helps with all that. Highly recommend on mature skin since I’m in my 40’s those pesky fine lines look smooth.

Best foundation ever!!!
Style: Refill, Color: Suntan
I was upset with my old powder foundation that is from another name brand that is advertised a lot for women over 40. I asked my dermatologist to see what she recommended. She said they use Jane iredale. I tried it and I’m so very happy. It actually covers my face and I’m not as self conscious anymore. The color match is great, and the foundation feels so light on your skin.
