The Gillette Venus Smooth replacement head features 3 curved blades surrounded by protective elastomer comfort pads that smooth skin for a quick shave with results you can count on! The swinging head responds to subtle changes in the contours of your body. The moisturizing belt enriched with aloe vera improves the glide of the device on the skin. The heads also feature a blue indicator strip that disappears to alert you that you are no longer shaving optimally. Based on shaving twice a week, each head will last you up to 1 month.
