How do skin care products penetrate the skin?

Chemicals can be absorbed into the skin, that is how nicotine and HRT (hormone) patches work. Many chemicals are delivered into the blood stream. There have been many studies showing to side effects on the body of absorption from chemicals from plastics, pesticides, cleaners, paints, skin and personal care products. The skin is not impermeable. For more information see free reports at www.nochemicalcosmetics.com

Skin Care products are not absorbed by the skin. They work on the skin's surface to moisturize it, exfoliate (cause the top layer to peel) it, firm it, etc. Your skin is an impermeable shield that protects you from germs and viruses.
