Either skin science has been progressing rapidly and consistently for decades or they're lying to us. Every couple of months there is a "new revolutionary breakthrough in the fight against aging", but what actually changes? Are the creams, lotions and moisturisers you use today that much better than what you had a year ago? Five years? How about what your mother used? I call shennanigans on the whole industry.

PS - If every breakthrough was truly so, today's skin care would be orders of magnitude more impressive than in the past.
PPS - That's not to say there aren't good products, but not every one of them can be "revolutionary".
