New year, new you. The first step: your skin. If year-long New Year's resolutions aren't your thing, we've put together a step-by-step skincare plan that shows results after a short month-long stint. Our staffers tried four regimens, all of which made for brighter, smoother skin—and they can't stop gushing about them! Are you ready to start gushing too?

THE RX: Consider glycolic acid the MVP of this regimen. In a cleanser or moisturizer it will help "remove dead skin and speed cell turnover, so skin looks less wrinkled over time," says Dr. Alexiades-Armenakas. During the day, she suggests a vitamin C serum to increase the production of skin-firming collagen, and then a moisturizing sunscreen to protect from cell-damaging free radicals caused by the sun. At night: a retinol lotion—spiked with hydrating hyaluronic acid and firming peptides—to (gently!) stimulate collagen.
