Advertencia: éste es un posteo “pesado” que puede sentirse como si estuvieras de nuevo en la escuela y no para lo más divertido (como el baile de graduación). No es necesario que lo leas, pero su objetivo es transmitirte la complejidad del metabolismo y la biología molecular de la piel y por qué nunca tenés que buscar un ingrediente “mágico” cuando de la juventud y la salud de la piel se trata. En resumen, la vida (VIDA) es complicada. Tu piel está viva. Debajo de unas pocas capas de células muertas en la epidermis, perfectamente diseñadas para el duro trabajo de proteger tu cuerpo de la contaminación y el daño,…

Warning: this is a “heavy” post that may feel to you like you are back in school and not in a good way (like for prom). You don’t have to read it but the objective is to convey to you the complexity of skin metabolism and molecular biology and why you should never look for a “magic” ingredient when it comes to skin youth and health. In short, life (LIFE) is complicated. Your skin is alive. Below the few layers of dead cells in the epidermis, perfectly designed for the tough job of protecting your body from pollution and damage, is the basal cell layer. Here is your stem cells…

Note: as usual, please feel free to skip stuff as you wish. There is a lot of “jargon” below. Do you remember the stories about sirtuins, resveratrol and the “French paradox”? Sirtuins are proteins with a very important role in the cell: they control the enzyme that converts acetate, a source of calories, into acetyl CoA, a key point of entry to cellular respiration. Because of this crucial role, it has been proposed that it may be possible to control age-related disorders in various organisms, and in humans. These disorders include obesity, metabolic syndrome, type II diabetes mellitus, Parkinson’s disease and the “ultimate disorder”: aging. What is the French paradox?…
