Hey Barbiedoll! I also want to give retinamicro a try but i hav had kind of bad experience with erythromycin, it also coontains tretinoin which made my skin very red and dry but i did notice improvement in acne. I only stayed on it for 6 weeks as i was expecting a better treatment. Do update your progress with retinamicro since they claim that the gel is released slowly and not at once thus not giving lot of peeling and redness. Did u notice any improvement yet?
