Review Overview

Amazing Base Loose Minerals SPF 20 contains titanium dioxide and zinc oxide as the active sunscreen ingredients and these definitely contribute to the powder’s opacity, cling, dry finish, and long-wearing capabilities. This loose-powder foundation is talc-free and has a very smooth texture that tends to get drier in feel and appearance the longer it’s worn. You can use it dry or can mix it with a moisturizer to approximate a liquid foundation or to allow for easier application over drier skin. (Keep in mind, however, that mixing it will diminish the powder’s sunscreen properties.) Either method can be messy, which is true for any loose-powder application, and that’s a definite drawback. Amazing Base provides medium to full coverage. The smooth, dry texture and comparatively lighter finish (though it still looks like powder makeup) with a faint bit of shine is preferable to many other mineral makeups. It is much less shiny than the bareMinerals foundation from bare escentuals. Most of Iredale’s 17 shades are superbly neutral, but some go on a bit lighter or darker than they appear, so testing them on your skin is imperative. The only shade to be careful of, due to its slight peach-rose tone, is Honey Bronze. The shades for darker skin tones are worth considering, but careful testing is a must because the high mineral content can cause these shades to look ashen on some skin tones. Despite some minor drawbacks discussed above, this is still worthy of our highest rating because it is great for sensitive or rosacea-affected skin.


Active: Titanium Dioxide (14%), Zinc Oxide (6%) Other: Mica, Boron Nitride, Zinc Stearate, Plankton Extract, Algae Extract, Punica Granatum (Pomegranate) Extract. May Contain: Iron Oxides, Ultramarines, Chromium Oxide Greens

Brand Overview

Jane Iredale At-A-Glance

Strengths: Lip balm with SPF 15 (a rare find); some impressive makeup, particularly the powder-based products; most of the makeup brushes are good.

Weaknesses: Skincare isn’t Iredale’s strong suit; mostly bad concealers; PureMoist LipColours SPF 18 contain irritating peppermint; some superfluous specialty products.

The Jane Iredale line primarily features its mineral makeup, along with several other cosmetics. The skin-care selection from Jane Iredale is limited to a few ancillary products, although a couple of them are definite options if you're a fan of this line.

Iredale's color line is advertised as "The Skin Care Makeup," but it isn't skin-care-like at all, at least not in the way you may imagine. Ingredients like boron nitride, mica, and zinc stearate (also known as zinc soap) have no benefit for skin, and they are the primary ingredients of Iredale's loose powders. A few of the products do include mineral-based, gentle sunscreens and a smattering of antioxidants (though the packaging will render them unstable after opening). The ingredient lists are also relatively short, which is beneficial for those with sensitivities, but that's about as skin-caring as this line gets.

You do need to be wary of some of Iredale's questionable claims, such as "Because our bases are concentrated pigment, the coverage we can achieve is far superior to normal makeup with a minimum amount of product. This is why mineral makeup should always look sheer and natural." These powders can be applied sheer, but the very nature of these ingredients results in products that are heavy-textured and that, like it or not, can look powdery and "made-up" on the skin. This is especially true if you have any dry patches, because these mineral powders, which also claim to "trap moisture," will exacerbate any dryness and can look caked and change color over very oily areas. Actually they do trap moisture, but they trap it away from the skin. That's the nature of any powdered mineral - they are absorbent and as a result can be drying.

Iredale denigrates talc, dismissing it as cheap filler material and an irritant, but talc is the essential backbone for a number of the most luxurious-feeling powders you will find, some of which have a softness and virtually seamless finish on the skin that other lines (including Iredale's) should envy. And talc is not irritating, at least not any more than the mica Iredale chose to use in its place. Even more significant, talc is a natural ingredient and a mineral. Despite this, all of Iredale's claims revolving around how mineral makeups are better for skin are marketing hype to the max. The most important element of her mineral makeup is the overall gentle, fragrance-free formula that provides outstanding sun protection.

If the concept of a powdered makeup different from the traditional talc-based powders you've seen at the cosmetics counters or drugstores appeals to you, then this line presents some fine choices. We would recommend using caution when you read (or are told) about the inflated benefits of some rather ordinary but nevertheless effective ingredients. However, with a few exceptions, there is certainly nothing in these straightforward formulations that’s harmful or irritating, and that's always beneficial.

Best foundation I've ever tried

I learned about this make-up after enduring a brutal skin cancer surgery on my face. Jane Iredale products were sold at the office next to my skin cancer surgeon, and were also recommended by the dermatologist I see regularly. Aside from a skin cancer scar, I have sensitive, aging skin. Amazing Base surprised me with how well it covered flaws and scars, as well as how it improved the overall appearance of my complexion. It also provides the sunscreen my doctors insist I use daily. Wonderful.
