Pielea nu este o simplă „învelitoare”! Dr. Cezar dezvăluie cum funcționează „gardienii” invizibili care decid ce poate trece în organism

Dr. Cezar compares skin and intestines to fortress walls, emphasizing their barrier functions against external substances. He explains that while skin can absorb certain molecules, this does not imply toxicity. The skin's outer layer protects against water loss and environmental agents, while the intestines selectively allow nutrient absorption. He also discusses hair follicles as sensory antennas connected to the nervous system, explaining the physiological basis of goosebumps. The article highlights the importance of evaluating cosmetic ingredients based on their specific properties rather than assuming all absorbed substances are harmful.
