Do Care by Stella McCartney products contain chemical preservatives?
No. We have run all necessary tests to anticipate potential allergies (clinical tests under the supervision of dermatologists). According to the results of different tests (in which each product is used for three weeks on 20 women with a dermatological exam at day 0 and day 21), we certify that all the products are safe for a cosmetic use in normal conditions. Granted, the essential oils used in our products do contain allergens, but they are listed on the product label so that you can easily avoid ingredients that may cause you irritation.
