TikTok is loaded with skin-care knowledge, but it's important to remember that it's no substitution for a doctor's personalised expertise.
"These days, I see people assuming that what works for a friend, coworker, or stranger on TikTok will work for them," said Dr. Hartman. "Everyone has unique skin-care needs, issues, and goals. Just because someone that you know used a product and had phenomenal results doesn't mean that the product is well-suited for you."
His advice: take everything you see on social media with a grain of salt, and when in doubt, ask a doctor. "Next time you're tempted to tell the girl on Twitter with the perfect skin to 'drop the skin-care routine,' ask yourself if you know anything about the road that it took to get her there."
