You can try using a heated razor with a hydrating blade, like the one below.

Warm skin is more susceptible to razor bumps and burn, but the experience of a hot shave feels far superior. They’re designed to be thrown away once the razor blades wear down. “And they have a much more forgiving learning curve than a straight razor (although those can be great too if you are willing to put in some practice).” Disposable Razorĭisposable razors come in one piece. Our expert stresses that if you plan to invest in a good razor, consider switching to a single-blade safety razor: “They give you the most control as far as following the grain of your facial hair,” he says. As for its construction, there’s a safety mechanism that locks in a disposable razor blade. Safety razors are easier to use than regular razors, and, in fact, they’re what first helped men shave beyond barbershops. Once worn, the head can be thrown away and a new one can be attached back onto the body. Types of Razors Cartridge RazorĬartridge razors come in two parts: the reusable body and the disposable razor head. For folks with thin or wispy facial hair, just about any razor will do, but it’s important to pick one that works well for your skin type, too. Safety razors, for example, and especially Bevel’s, are gentler on coarse, curly hair and help prevent ingrown hairs. “Shaving with the grain won’t get quite as close of a shave but is far less irritating and much easier on your skin.” Hair TypeĬertain razors will work better for different hair types. “Shaving against the grain will get the closest shave, but is also the most irritating and can lead to ingrown hairs and inflammation if not done carefully,” our expert says.
That being said, as much as a good razor will help you, proper technique can prevent irritation, too. Razors with hydrating heads, gel coatings or weighted blades help reduce friction, resulting in a smoother shave with fewer hiccups and less of a headache afterward. A regular razor will wreak havoc on sensitive skin. I’ve labeled them to the best of my knowledge.Folks with dry or easily irritated skin need specialized razors. Looking at the back of the board, there is not much there with the exception of the ICSP pads, which may be handy if you are inclined to try reprogramming the thing. In both cases additional signal diodes are added to intentionally raise activation voltage for the LED in series.

To turn both on, a normal full swing pulse is needed, but for LED2 only mode the line gets driven high and then switched to input. LEDs for the second and third speed segments are driven similarly (Waveform 2).
To drive green on, the output is driven high and then switched to an input (or Hi-Z state), so that lower voltage ends up somewhere between battery voltage and supply voltage. Since the same pin is also used as an ADC input, the battery voltage could be sampled at that stage. The most obvious optimization was done by grouping things together- lower LED is always on with the motor- might as well drive them at once. The red/green signal (Waveform 3) is more involved- to drive red the microcontroller switches to open drain mode and only pulls down, generating pulses between Vbat and 0 V. The razor uses 4 green and 1 red LEDs, but PIC10 here only has 3 pins available for all of them. It gets a bit more interesting with the LED multiplexing. Speed is adjusted by varying duty cycle of the PWM signal (It goes in steps of 40%, 60% and 97%). The motor is powered directly from the battery voltage and is controlled via an NPN transistor. The design is somewhat predictable- we have a 3V boost power supply feeding the PIC microcontroller.
