I've pretty much used most of the shaving options on the market such as beard trimmers, high end foil shavers, rotary shavers, straight edge razors, and traditional store razors with a badger brush kit. I'm the hairiest Asian alive, I can grow a full beard in about 4 days, the typical 5 o'clock shadow arrives at noon for me, it's a blessing and a curse, however it gives me great variety. My skin is incredibly sensitive, plus my neck hair can grow in many different directions, so below is my perfect setup.
I subscribe to Dollar Shave Club. I use the highest end blade they offer which is The Executive, and it has five blades, plus a straight edge blade on the reverse side for lining up the sideburns. It blows the Gillette's out of the water from a quality, and price point. It's $9 per month with free shipping. You get a pack of blades, and the handle, with some pretty cool packaging. You can delay shipments to stretch your dollar, but it's truly worth every penny. Their shave butter is fantastic, however I opt for Cremo Cooling Shave Cream at the local market.
Routine:
1. Hot shower to open up those pores and loosen up the facial hair.
2. Light lather of my face with Cremo peppermint shave cream, a little goes a long way.
3. Get my DSC blade hot, and make one pass going with the grain, second pass against the grain for closeness.
4. Rinse the cream and hair off, then apply cleansing facial scrub.
5. Repeat every other day.
This method keeps my shave close with absolute minimal irritation or cuts. I've dropped a decent amount of money trying all types of shavers and shaving methods, however the above works the best for my skin and my facial hair in general. I use a standard beard trimmer with a guard to trim the beard length and manscape. Being clean shaven definitely gives me a younger look, and having the option to rock a confident man look with a full (but well groomed) beard is great.
Note: I have not tried the Oneblade, however I feel like with foil trimmers, I won't get the closeness I want. I'll have to do more research to form a more educated opinion on it.
