No, as I stated already, the reason why I don't have beauty products is that they wouldn't do anything to benefit me.
Anti aging creams aren't aimed at you as you're male, therefore you don't think they would benefit you. They rarely have a benefit, they're usually overpriced crap sold as the elixir of youth - it's about focusing on women's insecurities.
You haven't had a lifetime of socialisation reducing you to your looks and playing on your insecurities. You don't buy beauty products because they're marketed at women. The beauty industry is predominantly about women.
The fact that they are aimed at women is irrelevant. If they were aimed at men, I still wouldn't buy them, because again, they wouldn't do anything.
You think that because the sexes are socialised differently and these products aren't relentlessly marketed at you. Beauty products do do something, make up is used to enhance your attraction, hair products are used to style your hair.
As for why some women buy makeup and beauty products, I can't answer that because I'm not those people.
I've already answered it because they're aimed at people like me.
If the goal of bulking up was to take up more space, then most men would be opting for the "strongman" build. Most gym rats aim to be like bodybuilders (muscular with a low body fat %), but clearly bodybuilders are not nearly as big as strongmen.
It depends why you're working out. Many men want bigger muscles and visible abs, hence the low body fat. They don't do weights to get smaller, they do weights and take protein to get bigger. Men also take steroids to bulk up quicker.
Whereas women are perceived as more attractive when they're thinner. Skinny men aren't seen as particularly attractive.
