In any case, although cosmetics give you an undeniable advantage when it comes to controlling your appearance, they come with the burden of deciding when and where their use is appropriate. The following points explain what men think about seeing you done up or in your natural state, so that you can better choose between the two when that decision proves difficult.
5. He loves a woman who is confident in her own skin. Confidence is a character trait that both sexes find incredibly attractive in the other (even if women value it more than men) because confidence is rooted in a healthy self-perception and acknowledgement of one's own self-worth - which all diligent and contentious people have. The attractiveness of your confidence is much more important than whatever advantage you sacrifice by occasionally being seen without makeup.
7. There is something intimate about seeing a girl without makeup. When I've seen my ex-girlfriends without their hair and makeup done, I've had two thoughts: (a) she is less attractive, but (b) it is nice that I get to see this side of her. It is an expression of intimacy - and her confidence - that she can be herself in my presence, and this is worth something. Don't use this as an excuse to ignore point #3, but allow it to help you if you struggle with point #5.
8. He isn't expecting you to be as hot without it as you are with it. Men understand that you aren't going to be as beautiful without your makeup on and hair done. This is expected, and it is factored in to their evaluation of your attractiveness. Yes, there are some women who get more benefit from makeup than others, and it is possible for a man to be surprised by how much less attractive a girl looks without it. You can avoid falling into this category by understanding your complexion and wearing makeup that is compatible with your natural look; but regardless, know that men definitely hold you to lower standards when you aren't made up.
A final point is worth noting: a genuinely feminine woman loves looking her best. She takes great pleasure in adorning herself and amplifying her internal beauty via her external beauty. You don't need to be a supermodel to enjoy this; you simply need to know that you are looking your current best. The more you allow yourself to enjoy looking beautiful, the less you will resent the "need" to do so, and the more comfortable you will feel when you don't.
