I don't have much to say about personal hygiene items or cosmetics. I use a moderate amount, and I buy mid-range brands from the drugstore or Target. What I spend on these items doesn't add up to a whole lot, and I'm satisfied with my spending in this area. It's not rock-bottom, but I'm satisfied with my cost-to-reward ratio.
However, I can add a valuable comment on skin care:
Around the time I turned 40, I developed some facial skin problems. Down the middle of my face (especially on my cheeks) I had red, raw-looking skin. Think about a movie where you've seen a stereotypical Irish drunk -- red, almost raw-looking skin as if he or she has been standing by a fire. That's what I looked like. Add to that large, nothing-will-cure-them pimples along my jawline. At the same time, my super-oily skin changed to ultra-dry, but only in patches. The dryness was actually painful, and my skin came off in small-to-medium flakes. I was very self-conscious about this, it was unprofessional at work, and other people definitely noticed.
I wasted about two years trying all sorts of remedies. Cheap store brands, expensive moisturizers, home remedies. Every single one of them worked, some to a greater degree than others, for a week at most . . . then the problems'd creep back, and the dryness was growing worse in spite of using moisturizers multiple times a day. Plus, as I said, the dryness was actually painful.
Finally, exasperated, I went to the dermatologist. He immediately diagnosed Eczema and Roseacea. With a couple prescription creams, he cured the Eczema and got the Roseacea under control. He also clued me in to a specific type of make-up that covers the bit of redness that sometimes comes through, and he told me to use a specific type of over-the-counter moisturizer that's appropriate for my skin. In one visit, he fixed what I couldn't fix in two years.
The cost:
I don't know what I spent in the two years that I was trying all sorts of over-the-counter products. Typically, on a day when my skin was really flaring up and I was feeling horrible about my looks, I'd go to the store and pick out some skin care product that was new to me, and I'd buy it. Sometimes it was cheap, sometimes it was expensive. Since they never worked long-term, I rarely finished using the bottles, so it was very wasteful AND expensive. I'm sure I spent several hundred dollars per year -- and for no result.
When I began going to the dermatologist, I had three visits over the course of three months ($30 copay each) and several tubes of medication. Today I have one doctor visit per year. I keep one tube of the $25 Eczema medicine, though I rarely use it. I use a $25 tube of Roseacea medicine about every 2.5 months. The foundation make-up he recommended costs $21 and lasts about 9 months. The moisturizer is $7.50 and lasts about 2 months. While this isn't super-cheap, it WORKS to keep my skin conditions under control. I no longer am embarrassed by my skin, and the Eczema pain is gone. This is MUCH LESS than I was spending when I was stabbing in the dark, trying to find a cure in the drugstore.
The moral: When you have a skin problem, just go to the dermatologist.
