Gillette Fusion5 Power Replacement Razor Blades rely on five anti-friction steel blades to shave your facial hair while still offering top support and comfort. In fact, these also feature a Flexible Microfin Comfort Skin Guard to protect as well as stretch/smooth sensitive areas and a wider lubrication strip. You're likely to achieve effective results thanks to soothing micro-pulses that allow the blades to glide easily over the skin. Moreover, each refill provides up to 20 close and long-lasting shaves considering they also feature a wide lubrication strip. Although the precision styling trimmer is not a novelty, these replacements suit a powered alternative of the Fusion5 razor. Hence, they come with a unique stabilizer positioned right in the middle of the blades, keeping the right distance between them. For optimal results, use in conjunction with Gillette's Fusion5 Ultra Sensitive Shaving Foam or other options from the same range. Characteristics Contains: eight refills; Razors per blade head: five; Blade head features: lubrication strip, precision styling trimmer, blade stabilizer, Flexible Microfin Comfort Skin Guard ; Compatible with: all five-blade razor refills, except GilletteLabs' models. How to use Before using the Gillette Fusion5 Power Replacement Razor Blades, cleanse the face and spread your preferred shaving foam. Switch for a new blade when the lubrication strip's color starts to fade or each razor stroke feels duller than usual. Press the button at the back of the cartridge for a smooth release. Then, slide the handle into the replacement refill and wait for a clicking sound. Finally, proceed with your grooming routine and wash/rinse the blade carefully.
