Retin-A and, to a lesser extent, Retin-A Micro, produce symptoms of peeling, itching, redness, dehydration and photosensitivity.
Gernetic Synchro and Gernetic Nuclea provide alternative sources of active Vitamin A without these symptoms, and are suitable for rosacea.
Gernetic Cytobi can also be used in place of Synchro, for even more concentrated ingredients, and is preferable in case of very sensitive skin, such as that thinned by inappropriately prescribed or overused steroids.
