Everyone’s skin is different. This means that everyone’s reaction to MONO’s products is going to be different. How quickly and effectively your skin responds to MONO products depends on the severity of the skin issue and other mitigating or aggravating circumstances. Some of our customers who suffered from skin inflammation reported positive results in 2-3 weeks of regular use. If you are having a serious outbreak of acne, rosacea, or eczema, or, if you are using prescription medications for any of these conditions, please consult with your physician.
