Apply Retinal Smooth to your night routine. If you notice any discomfort (redness or burning sensation), we recommend a retinization period: the first week, apply three nights a week, leaving 2 nights between applications; the second, one night on, one night off; and from the third week onwards, if there is no irritation, you can increase the number of applications.
