Black powder on skin after shaving.

My electric razor leaves my face black. I have changed the screens & the cutters, but it is still leaving my skin covered with a black coat. It washes off okay with soap & water & it is not oily. I've had the razor about 3-4 years. It is rechargeable. The problem just started about 3 weeks ago.

Re: Black powder on skin after shaving.

I have the same problem and the 2 previous answers are not even close .. my issue started when I replaced the screen and cutter on my razor .. I think it is just inferior metal used for the replacement screens. It is a smudge that is in no way related to metal shavings or dzrk hair ...

Re: Black powder on skin after shaving.

Pressing too hard causes the blades to wear away the screen & leave the tiny scapings of metal on your skin. Lighten up.

Re: Black powder on skin after shaving.

If you have dark hair, or dry skin, this could be the reason for the covarage on your skin. The shaver is cuting your hair, then "spiting" the hair back to your face.

How to use an electric shaver

If you are a using an electric shaver for the first time, I hope that this article will get you going. Proper techniques will ensure the best, closest shave possible. Maintaining the razor by properly cleaning and recharging it will also ensure that the razor works correctly and does not malfunction during use. Proper care and maintenance of the electric razor will also ensure that the razor will last for years to come. Consider this article as a shaving-best-practices template for your first electric shaver.<br /> <br /> Firstly, clean your face and dry it. Electric shavers do a better job when your face is clean. Turn the electric razor on and begin shaving against the direction of hair growth, moving the shaving head linearly and in circles. Circular motion Stretch the skin with your other hand to make the hair stand up straighter so the razor blades shave closer.<br /> <br /> After shaving, turn it off and rinse the cutting heads under warm water. You can also use jet clean system once a week to clean your shaver. Make sure that you charge it for the time specified in user manual. Overcharging may cause damage to the battery.

What does a flashing red light at bottom of display when you turn razor off mean looks lit the 3 rotary blades

It means they want you to buy a new shaver head. U dont need too, and the light will automatically go off after 7 shaves from when it first came on.

Helloi bought my boyfriend a Braun electric razer series 150 for Christmas. He has not used it too many times and now it has been scratching his face. Does he need to lubricate it or is there a problem...

try giving him an aftershave balm this will sooth the itchiness I use it and it works fine also if its the first time he's using it he must get use to it as electric razors offer a closer shave when used properly than normal razors.
ps ALWAYS use electric razors on DRY skin

Is the Braun Activator8595 a good shaver for extra sensitive skin

The Braun foil shavers are well designed and I find they work well for sensitive skin if you prepare properly. Make sure you apply a hot towel to your face followed by a shaving conditioner. When applying the shaver, press lightly. Don't be afraid to go over the same areas several times to get most of the whiskers. Once you do this for about a week, your skin should begin to adapt to the sensation of electric shaving. You'll then be able to use the shaver more aggressively and get a thorough shave.

Not shaving close enough.

This problem is usually cause by a worn out shaving head (foil and cutters). Braun suggests that you change these every 12-18 months for best performance. You will find replacements at for your model 4501 Braun shaver. See link below.

It is also possible that your shaver is running too slowly due to an old battery if you've never replaced it. If you require a new battery, it can also be ordered from See link below.

To change the battery you will need to be able to do a little soldering. Open the shaver by removing the two round screw covers on the bottom of the shaver and then the screws underneath. You will also need to remove the foil and cutters and then the swivel frame which is attached by two tiny screws. Once removed, you will be able to open the shaver from the bottom and seperate the front and back. Remove the circuit board to easily get to the battery.
Note: The tabs on this type battery will work for most applications however they may be slightly different than some original equipment. For these instances, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather that removing them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can them solder the tabs from the new batteries to the old existing tabs
