I feel for your sister!
She not only has a dryer climate against her, but also the higher elevation!
After living out west for nearly 2 years…and then moving back east…I see dramatic changes in my skin and body.
My hair and nails would break off, my facial wrinkles we’re more noticable, my skin was dry, flaky and chapped, and I felt very light-headed and had headaches MOST of the time.
After moving back east I feel as though my body is flourishing…hair and nails are healthy and growing, wrinkles seem to be MUCH less noticable,. It’s almost like an aging reversal.
I will have to find pictures to illustrate this.
