We love Dakota Johnson for many things, including her espresso “liquid hair” (aka the shiniest strands in Hollywood), her impeccable street style, and the wide-ranging portfolio of characters she’s added to her résumé throughout her storied career. So when she arrived at the New York City premiere of the hotly anticipated book-to-film adaptation of Verity, written and coproduced by Colleen Hoover, our group chats were instantly aflutter with oohs and aahs over her beaded-fringe two-piece from Calvin Klein, blood-red lip, and half-up, half-down hairdo spotlighting those iconic bangs. When her makeup artist told me that the secret to her red carpet–ready skin was the exact same brand my mother uses religiously, I had to press for more.

After discovering the brand at the behest of her dermatologist, my mom became a devout fan of Drmtlgy’s medical-grade formulas at affordable prices—relying on everything from the collagen-spiking growth factor serum to glow-enhancing peel pads and shocking facialists with her age along the way. Seeing her fast results, her friends quickly jumped on the bandwagon, and apparently, Johnson is in on the secret too.
