hot take: most "biohacking" skin devices are placebo + LED

looked at the clinical data on 6 popular at-home devices. LED masks in the right wavelength + dose: real but modest. microcurrent: weak evidence, mostly temporary. 'collagen activating wands': nope. the marketing budgets are larger than the studies. save your money, go get a real in-office treatment every 6 months if you want actual results.
