To really kick things off with a bang, I am composing a tribute to soap. Soap is amazing. It's simple, effective, and altogether incredible. Don't listen to those stupid Dove commercials.
Contrary to what this Unilever brand would like you to think, soap does not, in fact, leave residue. For those not in the know, many of bars of soap-like material found in grocery stores and other shops (including those most likely used in this commercial) are not actually soap. Rather, they are detergents mixed with lathering agents that strip your skin of healthy oils and our natural protective layer of cells and moisture. These products might be labeled as beauty bars, cleansing bars, facial bars, etc. They may give you that "squeaky clean" feeling in the short term, but in the long run they dry out your skin and cause a number of other maladies like increased oil production, acne and blemishes, wrinkles and fine lines, and generally dull-looking skin. It's good news for the companies though, because then they can hock expensive greasy creams and other snake oil products to us.
While natural, well-made soaps are composed of healthy fats and oils, herbs, milks, and other shiny, happy ingredients, beauty bars like Dove are made of petrochemicals and things like BHT, Sodium Lauroyl Isethionate, Cocamidopropyl Betaine, Tetrasodium EDTA, and Fragrance. Even if all of those ingredients aren't terribly harmful, they definitely don't sound so fresh and clean, now do they? To top it all off, these "beauty bars" are the ones that actually leave more residue! Here's another way to look at it: soap has been used for thousands upon thousands of years to cleanse our skin. Detergent has always been used for dishwashing and laundering. Only recently has it invaded skin care as a faster, cheaper alternative to soap.
In short, detergent is for dishes, laundry, and kitchen counters. Not for skin.
