Use: Before shaving, it is recommended to rinse your face and neck with warm water, thoroughly cleansing the skin of impurities. For a better effect, you can steam the skin during a hot shower or with a warm towel applied to the face and neck for 2-3 minutes. The blades are excellent for use with shaving foams and gels. The razor does not require strong pressure; avoid it to prevent skin injury. Gillette Mach3 replacement cartridges are compatible with all Mach3 razor handles. One cartridge is designed for approximately 13-15 comfortable shaves. The moisturizing strip on the cartridge serves as a wear indicator: if it turns white, it's time to replace the cartridge. Contraindications: Avoid strong pressure on the razor to prevent injuries. Do not use dull blades, as this not only reduces shaving quality but also increases the risk of irritation and cuts.
