How Often Should You Really Change Your Razor Blades?
Most skincare experts recommend replacing your razor blades regularly to avoid skin irritation, razor bumps, and ingrown hairs. Depending on the body area, hair density, and shaving frequency, the ideal interval usually falls between 5 and 10 shaves per blade. A sharp blade glides smoothly over the skin, requires less pressure, and reduces micro-injuries, the main cause of razor bumps.
Different Body Areas, Different Needs
Face
Thicker, denser hair makes blades dull more quickly. Many sources recommend replacing them every 5–7 shaves. If you have sensitive skin or are prone to razor bumps, switching even earlier can help.
Legs
Hair is typically finer, so blades last a bit longer. A change every 7–10 shaves is commonly suggested. If the blade starts tugging or you need multiple passes, it’s time for a new one.
Underarms
Hair here grows denser, and the skin reacts more easily. Changing blades every 5–7 shaves can help prevent razor bumps and irritation.
Bikini Area
This delicate area benefits from the sharpest possible blade. Many recommendations fall between 3–5 shaves per cartridge, since dull blades can quickly cause redness or inflammation.
Why Dull Blades Cause Razor Bumps
Dull blades no longer cut cleanly, they tug at the hair, causing tiny skin injuries. These micro-cuts make it easier for bacteria to enter, which leads to razor bumps, redness, and sometimes ingrown hairs. Fresh, sharp blades minimize friction and keep your skin smooth and calm.
The Environmental Impact of Frequent Blade Changes
Every blade replacement creates waste, and conventional razor cartridges are made largely from fossil-based plastics. They cannot be recycled, and their abrasion releases microplastic into the environment, where it can accumulate and potentially impact human health.
Razeco tackles this problem directly. Our blade heads are made from 99% bio-based material, entirely free from fossil plastics, and can be disposed of CO₂-neutral. They cause no microplastic abrasion and significantly reduce environmental impact, even when you change blades regularly for the sake of your skin.
The Bottom Line: Good for Your Skin, Better for the Planet
Clear guidelines help you avoid razor bumps and irritation: depending on the body area, you should replace your blades every 7 to 10 shaves. Fresh blades protect your skin and with Razeco, you protect the environment at the same time.
