i had my first ever de shave last nite with a merkur 37c long handle and i used the blade that came with it, with that i also purchased a sampler of about 20 diff blade manuf. the sides of my face turned out great bb smooth but my neck turned out not so good. i had alot of nicks you may call them i dont think they are true cuts as they were very small dots. didnt bleed much at all, i have had the same problem before with a cartridge razor as i have sensitive skin. my neck feels very irritated today and almost painful to touch, that being said i never shave everyday due to the fact it hurts to much. any help would be appreciated. how long should i wait before i try again?
