Overall, I believe the jet lag mask is reasonably sustainable and good for the planet as well as the user as the few ingredients that are included which are of slight concern in terms of harm to the environment, are only used in small amounts, therefore, do not to be worried about too much.
Whilst the Summer Friday’s Jet Lag mask is vegan, fragrance-free, gluten-free, paraben-free and contains no dyes, it has several ingredients such as Caprylic/Capric Triglyceride and PEG 100 Stearate that according to ewg.org’s ingredient search list come up as possible environmental toxins as well as be toxic to humans and cause some irritation. Most of these ingredients that would be of concern are not used in significant enough amounts to pose an alarming threat to humans or the environment.
Summer Fridays is a skincare brand started in 2018 by co-founders Marianna Hewitt and Lauren Gores Ireland. One of the reasons behind starting the brand and their products was that during the production process of the jet lag mask (their first product) Gores Ireland was pregnant so had to be very careful about what skincare items she could use that were safe whilst being pregnant. Majority of their products are vegan, sulphate free, gluten-free, paraben-free and contain no dyes. They also do not test any of their products on animals.
The production process of the Jet Lag mask is not explicitly stated, however, Summer Fridays as a brand cares about sustainability and makes that very clear. The boxes that products come in are fully recyclable and they created a recycling program so that you can return 5 empty containers and receive a travel size version of the Jet Lag mask. The ink and dyes used on the packaging whether it be tubes or glass bottles are made from a recyclable source.
