Nivel facil A red onion skin hydrolate, the same pigment that gives the skin its color. Medium level Anthocyanins are natural pigments responsible for purple/red color; purple skins must be used, not white ones. Advanced level The final color outcome depends mostly on the rose variety's genetics, not just on nutrition. Preparacion Boil red onion skins in water for 10 minutes, let cool covered, strain and discard the skins. Keep refrigerated for up to 4 days. Limites The Library teaches physiology and reasoning; this bio-hack is a complementary homemade practice and does not replace Yolia's main formula or imply a guaranteed result.
