About the third point concerning the damaging skin care products: when a teenager, I used a product that, at the time, was a popular treatment for pimples and acne. However, I did not have acne, simply the occasional adolescent pimple. A couple of uses of the product caused a chemical burn that peeled at least one layer of skin off one side of my nose. It took years for my skin tone to even out.
Young adults need to be educated in proper skin care, and for their skin types. I spent a few years in the cosmetics industry doing just that by teaching a skin care class as part of our local high school health class, and, hopefully, saving a few kids from experiencing what I did at their ages.
Point 3 well-taken! I just wish I had known sooner.
