About Us

It Began with Healing Water and Calendula...from our inception in September of 2008, we have developed our formulas seeking the best natural ingredients with unique skin healing benefits. In fact, our original formulas still originate in Hungary where we first began with key ingredients of Hungarian Thermal Water and Hungarian Calendula Officianalis Extract, a natural herb indigenous to Eastern Europe known for reducing inflammation and redness naturally.


Specially Formulated for Skin Side Effects of Breast Cancer Treatments

Our products came into being out of a need for a better standard of comfort due to the side effects of breast cancer treatments that affect the skin. Our founder, Theresa Keresztes is a breast cancer survivor who treated her skin discomfort with Calendula after she developed radiation dermatitis while undergoing breast cancer treatments at Massachusetts General Hospital in 2007. Ms. Keresztes used the unique calendula cream she discovered in Hungary when her skin became unbearably itchy and red due to the skin side effects of radiation therapy. She later refined the cream for others experiencing radiation-induced dermatitis, a common side effect of radiation.
