In this eye-opening conversation, Dr. Teo Soleymani, Stanford-trained, double board-certified dermatologist and skin cancer surgeon, joins us on our regenerative farm (under the sun) to unpack some of the most common misconceptions about sun exposure, skin cancer, and the products we’ve been told to trust. 



Dr. Teo shines light (literally) on why the most deadly skin cancers don’t come from sun exposure at all. He breaks down the risks of chemical sunscreen ingredients, the truth about their absorption in the body, and how holistic sun protection starts from within.
