Is the over usage of single Gillette bla

Respective doctors my question is nothing but How many times should we use the Gillette handle Razer to shave our beard cleanly for a month ? Because I'm a man who has been habituated to use it for 16 times in a month with day left another day and I keep on continue the same Gillette handle Razer for three months continuously. It means that I've been using only one Gillette Razer handle blade for 48 times in three months. Now I'm asking u that is it good to use a Gillette Razer blade for 3 months continuously to our skin like that ? And I use a black colour dye to my hair once in a month. Meanwhile I got some black stains in my facial skin very ugly way as I showed u in photo below then I doubted that  whether it was because of over usage of the single Gillette handle razer for 3 months r black color hair dye that I apply for once in a month? Please clarify my doubts the black stains which I got on my face because of back hair dye r 48 times use of the Gillette Razer in 3 month
