In order to use your Philips electric shaver for a long time, you need to maintain it well. You do this by regularly cleaning the shaver head with a cleaning agent. That way, you'll remove fat, skin flakes, and bacteria. Unfortunately, it doesn't prevent wear. You can't prevent the shaver head for wearing, so we recommend that you at least replace the shaver head every 12 months. You'll need to know what type of electric shaver you have at home, though.
