In this episode, my guest is Dr. Teo Soleymani, M.D., a double-board-certified dermatologist and specialist in skin cancer and reconstructive surgery. We discuss science and clinically supported protocols to improve skin health and give your skin a more youthful appearance and structure, reducing premature aging and skin cancer risk. We discuss the impact of sun exposure on skin appearance and aging and the surprising relationship between sun exposure and skin cancer. We explain how mineral-based (inorganic) sunscreens differ from chemical (organic) sunscreens, whether sunscreen can minimize premature skin aging, reduce cancer risk, and if there are any health risks associated with sunscreen use. We discuss skincare routines to significantly improve skin appearance and how to select skincare products. We discuss how caffeine, nicotine, alcohol, and stress impact the skin and describe how nutrition and anti-inflammatory diets can improve skin health. We also discuss the causes and treatments for common skin conditions, including dandruff, acne, rosacea, eczema, psoriasis, and vitiligo. Our conversation also covers topics such as the use of retinoids, laser treatments, red-light phototherapy, supplements, and how to best monitor for skin cancer. This episode provides numerous actionable protocols, most of which are zero-to-low cost, for improving skin health and appearance, reducing cancer risk, and treating skin problems.
