Bioderma Sébium Night Peel is a specialized overnight treatment designed for combination to oily skin with blemishes. This smoothing concentrate works while you sleep to refine skin texture, minimize imperfections, and regulate excess sebum production through gentle exfoliation. The formula contains Bioderma's patented Fluidactiv™ complex that helps prevent pore clogging by regulating sebum quality. This night treatment should be applied to clean, dry skin in the evening. For optimal results, use as part of a complete skincare routine. The product comes in a 40ml airless pump bottle that helps preserve the formula's effectiveness. As with any exfoliating treatment, it's recommended to use sun protection during the day.
