Especial 8.- La piel también se enferma, las señales que no debes ignorar - Dra. Ana Cantú

The episode centers on how certain chronic skin conditions arise from immune system dysregulation rather than external factors alone. Dermatologist and clinical immunologist Dr. Ana Cantú explains that the skin often acts as the visible reflection of internal processes, where immune cells misfire and produce ongoing inflammation. She distinguishes these disorders from purely cosmetic concerns and stresses that they require targeted medical assessment instead of home remedies or concealment.

Immune-Skin Communication and Chronic Patterns

The immune system functions as a continuous defense network that normally identifies and removes threats while maintaining balance. Skin cells participate in this dialogue by signaling irritation or damage, prompting immune responses. When genetic or environmental factors disrupt this balance, immune activity accelerates or misdirects, attacking the skin's own structures. In psoriatic disease, this leads to rapid turnover of keratinocytes, shortening the normal 28-day skin renewal cycle to roughly three days and producing visible plaques. Atopic dermatitis instead involves a weakened skin barrier that allows external triggers to activate inflammation more easily. Both conditions fluctuate because immune regulation occurs in cycles rather than a simple on-off switch, which explains why symptoms can appear, fade, and return without resolving
