No Professional Photography

I think what you should do is keep the professional and highlight with him/her, what your insecurities are, and ask him to photograph in a way that hides them. For example, when it comes to your skin tone, you could ask him to edit and retouch the photos in a more muted fashion as opposed to a bright contrast. I mean you could also ask him to purposely make your skin tone lighter, even though I'm highly against changing your natural beauty. In regards to your negative feelings about your forehead, you could ask your hair stylist to mask them with some bangs and so on.

I'm aware that for you, photos aren't exactly all that big on your wedding list. Ultimately, it's your choice what you want to do with them. I mean if the only thing you want to remember your wedding day is a few photos taken on someone's cellphone, than by all means go for it. However, I will say this, at the end of the day, and as years pass by, eventually all you'll have left are photographs.
