How Jane Iredale tests their products

November 30th, 2013 | Posted by LEARN in LEARN School of Esthetics

Apart from mandatory tests including Sunscreen, Stability, and Preservative Efficacy, we also conduct voluntary tests that include:

 

Human Repeat Insult Patch Test

The irritancy and sensitivity test is two-phased and conducted on fifty people per product. 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 a 48-hour evaluation. In every case, no sensitivity has been recorded for any of our products.

 

Comedogenicity Tests

All of our products, except lip and eye makeup, undergo this test and prove to be non-comedogenic. Non-comedogenic products are less likely to clog pores and cause acne and are more suitable for sensitive skin.

 

Heavy Metal Testing

We test all of our products and every single shade of our lip colors to ensure that trace elements fall below allowable levels for heavy metals including mercury, arsenic, barium, cadmium, chromium, cobalt, copper, lead, nickel, selenium, and silver

 

Photo sensitivity Testing

All of our sunscreens products and those products containing citrus extracts have been tested for phototoxicity. The test results have shown that no adverse effects or unexpected reactions of any kind were observed on a test subjects. We avoid ingredients with furocoumarins, the primary cause of photosensitivity.
