Chemical free makeup companies?

I am a man. I have like three presentations at my uni per week that I have to give to 50+ people. I need to do something about my face, I think this is a pretty good excuse to use makeup since I have some nasty red marks all over my face.

So, I'm looking for a cosmetics company to cover my red marks. I've been googling for a few days and found very few companies that offer quality natural products. I am looking for a company whose products don't contain any ingredients that might aggravate acne or clog the pores. No parabens, mineral oils, fragrances and alcohol. In other words I am looking for natural products that do not have any possible skin irritants in them.

What would you recommend for a man anyway? Obviously I don't want anyone to realize I am wearing it. Only a concealer stick?

Is cooking with oilve oil a good idea?

I can't stand it's taste, so I just use it to cook. Is that a good idea? Someone said something about it losing its health benefits when heated or something like that.

"BP does not bleach eyebrows" - I TAKE IT BACK

BP has made my eyevbrows yellow/blonde. I didn't notice it before, but they have definitely changed color.

Is there any way to fix it? They should regrow faster if I plucked them right?

How do you deal with blackheads on the nose?

So, I'm pretty sure BP has caused the blackheads I have on my nose, and someone even explained why it happens.

What can I do about the blackheads? Should I just avoid putting BP on my nose? Whiteheads aren't any better to have...

Can you get away with skipping the regimen once?

Could skipping the regimen once lead to a breakout? I love clubbing and sometimes I end up sleeping somewhere other than my home and skipping the night regimen. (I haven't done that since I started the regimen). What do you think?
