Skin care products are required to get no government cetification on their claims. Hence its mostly marketing and giving/taking advantage of people with self image issues. Its the next step in consumerism to take advantage of mens wallets in the same way the beuty industry has been doing to women for years.
Soap and water will clean practically anything and if ya need it maybe some dirt cheap moisturiser for literally any part of your body will do the trick. Hell u can probably find something in ur kitchen that will do just as good of a job as any bullshit product.
Dont buy into the marketing mens beuty marketing is perfectly correllated with self image issues its all designed to make u a good little consumer.
Honestly the best thing u can do for your skin is go swimming in the ocean once a day.
