The MUDMASKY Leave Me On Winter Mask has been awarded the Seal of Acceptance™ from the National Eczema Association today!
This seal is considered the hardest recognition in the skincare world. To qualify, a product must go through years of independent testing, strict ingredient reviews, and scientific approval from leading dermatologists and allergists. For the Winter Mask, the process lasted more than five years and involved more than one thousand people across multiple countries.
The result is a moisturizer that is now one of the most carefully studied skincare products ever created.
Independent Testing on an Unprecedented Scale
Most skincare brands test their products internally or with small groups of volunteers. What makes the Leave Me On Winter Mask different is that every stage of testing was carried out by independent laboratories, without influence from MUDMASKY.
Over the course of five years, the formula was subjected to
- Patch testing on sensitive and eczema prone skin
- Repeat Insult Patch Tests that confirmed long term safety
- Clinical studies in both Europe and the United States, measuring hydration, barrier repair, and comfort
- Toxicological reviews of every ingredient under European Union and United States cosmetic law
- Real world trials with doctors and nurses who applied the product daily under surgical masks during exhausting shifts
The scale of this process is almost unheard of for a moisturizer. With more than one thousand participants included in independent trials, the Leave Me On Winter Mask has likely become the most tested moisturizer in the world.
From Innovation in 2018 to Lifeline in 2020
The Winter Mask was first launched in 2018 as the world’s first moisturizer designed for deep hydration during cold weather. Its rich and protective formula quickly attracted people searching for long lasting hydration, not just in winter but throughout the year.
When the COVID 19 pandemic struck, MUDMASKY made a bold decision. In the summer of 2020, the company donated more than € 100,000 / $ 120,000 (excluding shipping costs) worth of Winter Mask to hospitals across Europe and the United States. Doctors and nurses wore the moisturizer daily under protective masks and found much needed relief for dry and irritated skin.
Hospitals That Benefited
Among the many hospitals and hospices that received the donations were
- Lenox Hill Hospital in New York, United States
- Kingsbrook Jewish Medical Center in Brooklyn, United States
- University College London Hospital in London, England, United Kingdom
- Van Weel Bethesda Ziekenhuis in Dirksland, Netherlands
- Amsterdam UMC in Amsterdam, Netherlands
- UZ Leuven in Leuven, Belgium
- Centro Hospitalar Tondela in Viseu, Portugal
- St Anne’s Hospice in Little Hulton, England, United Kingdom

- Choctaw General Hospital in Alabama, United States
- University Hospital of Louis Pasteur in Kosice, Slovakia
- Sandwell General Hospital in West Bromwich, England, United Kingdom
- Royal Surrey Hospital in Guildford, England, United Kingdom
These donations reached thousands of healthcare workers at the moment they needed it most.

From Hospitals to Homes
The story of the Leave Me On Winter Mask is unlike any other moisturizer. It was created in 2018 as a winter skin essential. It became a lifeline for healthcare workers in 2020. And today, after five years of independent testing on more than one thousand people, it carries the highest recognition possible: the Seal of Acceptance from the National Eczema Association.
With this seal, the Winter Mask is no longer just a moisturizer. It is proof that skincare can provide safety, comfort, and trust for even the most sensitive skin in the world.
