The answer, of course, is to adjust your topical routine. Still, not everyone wants to swap their favorite moisturizer for a heavier cream, so here’s one tip you may be overlooking to keep your skin dewy year-round. For those with oily or acne-prone skin, using an astringent toner with ingredients like witch hazel, gentle exfoliants, or tea tree may help ease the shine. However, these astringent toners aren’t going to help you out in the winter. “Be careful not to overdo it, as astringent toners often contain alcohol and can be overly drying and disruptive to the skin barrier,” board-certified dermatologist Rebecca Marcus, M.D., FAAD, once told mbg. Instead, opt for a hydrating essence: This type of toner often comes free of drying ingredients, instead packed with powerful hydrators like hyaluronic acid, niacinamide, ceramides, and aloe vera. And if you want to take your cold weather skin care a step further, opt for a hyaluronic acid supplement in the wintertime as well. That way, you can hydrate your skin from the inside out; in fact, one study found that people who took 120 milligrams of hyaluronic acid a day for eight to 12 weeks experienced better skin aging1 (fewer wrinkles and more supple skin) compared with those who took a placebo. If you’re not ready to commit to a year-round practice, feel free to snag an HA supplement as your winter go-to—here’s a curated list of the best 13 options if you’re on the hunt.
