Regrets

Frankly, I find that hard to believe. When I was a teenager and had acne, I noticed a strange phenomenon after a while: the more often you shower, the fewer pimples you have... Need I say that shortly after this discovery, I almost had zero acne?

I don't know how rarely you used to shower, but I've never had any problems with the frequency of washing. However, for example, my sebaceous glands are very active, so pimples all over my body (yes, all over!) still bother me to this day (although, of course, the frequency and size are significantly different from what they were in my teens), and my hair gets dirty very quickly (the roots get dirty quickly and don't look great, although the rest of the hair is fine). But, of course, there is a downside: my skin never cracks in the cold (although many people have to use various moisturizing creams), my hair is in great condition immediately after washing (and sometimes even on the second day!), and I don't suffer much during good seasons (for example, in late spring, early autumn, and on cool summer days).
It's a different story when people neglect themselves. Then, yes, it's disgusting.
