Interesting read! Mmm I suppose I'm in the minority that I have no problem whatsoever leaving the house or being seen without makeup on. These days I am usually wearing only mascara and lip gloss/tinted balm.
Now, that said, my goal is to look very natural because it adds an organic element to my look that is missing from my personal style in terms of clothing. So I do other things regularly for the health and beauty of my face/skin that I certainly wouldn't stop or skip: daily use of SPF moisturizer (no color), professional brow wax every month, LOTS of water to keep my skin hydrated, exfoliate all skin weekly, lavender-based face wash in the shower daily, keep teeth clean (sonicare+mouthwash+floss) and visit dentist regularly.
