About Us

Product Testing

In the cosmetic industry, there are mandatory tests and voluntary tests. We do both. Because jane iredale believes in offering you the highest quality products possible, it has conducted tests not required of a cosmetic manufacturer, such as comedogenicity, photosensitivity and more. Your safety is important to us.

One thing we will never do is use animals in any of our testing. You can count on that!

Sunscreen – SPF (UVA & UVB Protection)

jane iredale conducts extensive testing of its sunscreen products to determine their efficacy in terms of UVA and UVB protection in compliance with both US FDA (Food and Drug Administration) and international requirements and testing methodologies.


jane iredale sunscreen products have always had excellent UVA and UVB protection and pass the new US FDA final sunscreen rule “Broad Spectrum” test which measures a product’s UVA protection in relation to its UVB protection.

Only sunscreen products that pass the Broad Spectrum test and have an SPF of greater than 15 may be labeled “Broad Spectrum” and make the additional use claims: “decreases the risk of skin cancer and early skin aging if used as directed with other sun protection measures.”

jane iredale sunscreen products have also been tested for their water resistancy pursuant to the new final rule which only allows “Water Resistance” claims if the sunscreen remains effective for 40 or 80 minutes while swimming or sweating. The new testing techniques have resulted in a 40-minute designation for all of our sunscreen products.


jane iredale sunscreen products are also tested pursuant to various international requirements, testing methodologies and rating systems, including those established in the EU (European Union) and by the JCIA (Japan Cosmetic Industry Association).

Our testing pursuant to EU requirements has resulted in a “UVA/UVB” claim which indicates that the UVA and UVB protection of the sunscreen are provided in a minimum 1 to 3 ratio. So, for example, a product with a UVB SPF of 30 requires a UVA rating of 10.

The JCIA PA rating system (also known as the “Protection Grade of UVA” rating system) reflects a sunscreen's ability to protect against UVA rays. The PA rating system designates a PA+, PA++, PA+++ to indicate lowest to highest UVA protection. The more plus symbols the label has, the more protection the sunscreen provides against UVA rays. Our testing pursuant to the PA rating system has resulted in a PA+++ rating for our Powder-Me SPF and a PA++ rating for all of our other sunscreens.

Testing of Sunscreen Actives

Each batch of our SPF products is tested to ensure that the sunscreen active it contains, either Titanium Oxide and/or Zinc Oxide, is present at its stated amount.

Stability Testing - Best Used by Date or PAO (Period After Opening)

All of our products have undergone stability testing, which includes various tests that measure a product’s shelf life. This testing helps to determine a product’s “best used by” date or PAO or Period After Opening date.

Products with a shelf life of 30 months or less include a “best used by” date. Currently, the only jane iredale products that bear a “best used by” date are our Hydration Sprays.

Products with a shelf life of more than 30 months include the PAO or Period After Opening, which is the number of months the consumer can expect to use the product at its optimal performance after opening the product. The PAO is indicated by the PAO symbol, an open jar and the lifespan of the product contents in months (indicated by a number followed by “M”).

Repeat Insult Patch Test

This is a sensitivity test conducted on 50 people per product. This is two-phase test which tests irritancy and sensitivity. During the first phase, the test is repeated three times on the same subject within a week. There is a ten to fourteen day break and then the subject is patch-tested for three consecutive days. There is a 24-hour evaluation and 48-hour evaluation. In every case, the results of being tested with our products were negative. No sensitivity was recorded to any of the products. The claims we can make are: dermatologist tested, non-irritating formula, allergy tested, clinically tested, and hypoallergenic.

PET – preservative efficacy testing

Preservative Efficacy Testing also known as Preservative Challenge Testing is performed on each product to prove the efficacy of the product’s preservative system to stop and prevent the growth of microorganisms. In a laboratory, the product’s preservatives are challenged by introducing microorganisms, including various bacteria, yeast and mold, into the product. Over a period of time, samples are tested at different intervals to determine the survival of the organisms. When the testing of our products is concluded no microbial activity is detectible.


jane iredale products are certified cruelty-free by PETA. To find out more about what this means, please visit our page on their site.

Comedogenicity Testing

All of our products, except for lip and eye makeup, have undergone comedogenicity testing and shown to be non-comedogenic. Non-comedogenic products are less likely to clog pores and cause acne and are more suitable for sensitive skin.

Heavy Metals

Heavy metals are ubiquitous in the environment and are found naturally in rocks, soil and water and therefore may be found in minerals, pigments and other raw materials used in cosmetics. Even after they are properly processed and purified under lab conditions, very low amounts, known as trace levels, may still be detectable in these ingredients or products. Testing allows us to detect heavy metals at very low levels and depending on the laboratory, technology utilized and material tested, these are measured in either parts per million or parts per billion. A detection of 1 ppm would represent .0001% of the total product formula.

We test all of our products for Mercury, Arsenic, Lead and Cadmium. If any trace amount of a heavy metal is detected it is below the permissible levels for cosmetics recommended by international public health agencies.

Particle Size

We have tested all of our minerals under laboratory conditions. Results show that there are no nano-size minerals in any of our products.


jane iredale has conducted tests not required as a cosmetic manufacturer, but it has done so because it believes in offering you the highest quality product line possible.
