Sample size of one here, but my skincare regimen consists of bar soap and water, and I appear to have healthier skin than people I know who have sinks and bathtubs FULL of plastic bottles and squeeze tubes of gunk that promises the cleaning power of [noun] or the moisturizing action of [noun].
I'm also pretty convinced that the special face washes they make for pizza faced teenagers are, at best, normal soap and/or detergent and have no special teenage hormone zit fighting powers.
Soap is a degreaser, lotion is a regreaser, sunscreen is a regreaser that has something in it that's opaque to UV, and anything that says it's got Vitamin Q and the moisturizing power of pumpkin spice is probably gunk, perfume and marketing.
