Here’s another one you might want on your radar: sulforaphane glucosinolate (SGS, or commonly referred to simply as sulforaphane). Quite a mouthful, but scientists agree this antioxidant is quickly becoming the next juggernaut of skin care. Here’s what you need to know about this sought-after ingredient. For years, researchers have loved this compound for supporting your body’s natural detoxification systems; one study even shows sulforaphane from broccoli sprouts activated enzymes in the body that picked up pollutants from the bloodstream and flushed them out via urine.* But while the benefits seem pretty gut-health-heavy, they seem to be making their way to skin care; in fact, new research keeps cropping up touting sulforaphane as the next up-and-coming antioxidant for skin.* “But that’s not quite how sulforaphane works,” explains registered dietitian Molly Knudsen, M.S., RDN. Rather, sulforaphane activates the protein Nfr2, which in turn activates certain antioxidant genes in your body. In other words, SGS doesn’t just stabilize free radicals the same way consuming vitamin C might—it activates the body’s natural detoxification and antioxidant enzymes. Essentially, sulforaphane can support your skin in the same way it does your body’s detoxification processes, flushing all the harmful players out.* Sulforaphane has also been shown to reverse photoaging by protecting against UV-induced skin damage. According to a study on sulforaphane’s protective effects2, using broccoli sprout extract for three days in a row prior to UV exposure helped manage skin cell damage.* What’s more, sulforaphane can provide healthy aging benefits; according to that same study, sulforaphane also helped maintain inflammation, which may spur the healing process for inflammatory skin conditions (like acne, for one).* Another study investigating sulforaphane as an antioxidant agent demonstrated similar protective effects against UV-damage, touting sulforaphane as a “very promising ingredient.”* That said, find a supplement that extracts sulforaphane from cruciferous veggies (like mbg’s grass-fed collagen+, for example) to promote your SGS absorption—and support plump, glowy skin3, to boot.* In terms of topicals, the jury’s still out on whether your skin can absorb the SGS the same way you can internally. According to Koffler, “There are some ointments and lotions on the market that contain broccoli seed oil, but research on their effectiveness is limited.” So even though massaging in formulas that boast SGS can’t hurt, you may want to stick to supplements and veggies for now. After all, a truly lit-from-within glow starts from the inside out, no?*
