Before we get into nan specifics and wide-ranging benefits of carotenoids, it’s important to understand tegument health, really your tegument shows signs of aging, and really nan ingestion of carotenoids helps to slow down aliases reverse this process.

Skin aging occurs arsenic a consequence of some intrinsic (or internal) and extrinsic (or external) factors.“Intrinsic factors are related to your property and genetics, while extrinsic factors see manner factors specified arsenic sun exposure, cigaret smoking, aerial pollution, [and] nutrition,” says Carmen Castilla, MD, a board-certified dermatologist successful New York City.

Unlike your soul organs, your tegument is straight exposed to nan elements, which makes it highly susceptible to nan aging effects of biology stressors. “Most of what we admit arsenic aging of nan tegument results from nan deleterious effects of UV radiation from sun exposure,” says Richard Granstein, MD, chair of nan section of dermatology astatine Weill Cornell Medicine and a technological advisory committee personnel astatine Elysium, a supplements brand.

UV harm causes inflammation, which leads to nan statement of extremist oxygen type (ROS) that disrupt nan people occurring chemic reactions that your tegument cells request to usability properly. This, successful turn, causes nan breakdown of collagen and elastin successful nan tegument and stimulates nan accumulation of melanin, which results successful visible signs of tegument aging for illustration good lines and wrinkles, tegument laxity, and hyperpigmentation.

Adding carotenoids to your regular tin thief combat these effects from nan wrong retired acknowledgment to their antioxidant activity, which fundamentally allows them to gobble up those ROS’s earlier they tin origin damage. “Carotenoids tin forestall immoderate nan UV-induced harm done nan absorption of UV rays and usability arsenic a free extremist scavenger,” says Dr. Castilla.

Dr. Grandstein explains that ingesting carotenoids tin chemically neutralize—or, stop—the effects of UV radiation connected nan skin, staving disconnected signs of aging.

Shapiro’s champion proposal is to “eat nan rainbow”—specifically red, orange, and yellowish varieties of plant-based foods—in some earthy and cooked form. “The type of processing will impact nan bioavailability of nan carotenoids,” she explains, meaning that definite preparations let for amended carotenoid absorption wrong nan body.

Additionally, because carotenoids are fat soluble, they’re astir effective erstwhile taken pinch a repast that contains fat. “This is existent for some nutrient and supplement sources," adds Shapiro.

Speaking of supplements, you tin besides get your carotenoids successful capsule shape “Generally, supplements incorporate higher concentrations of carotenoids than are consumed from a normal diet,” says Dr. Granstein. “The magnitude successful supplements is geared towards circumstantial endpoints.”

Shapiro recommends 2-3 servings of dietary carotenoids per time (or 20-50mg per day) for 3-6 weeks to spot visible changes successful nan skin. “It’s difficult to devour excessively overmuch pinch dietary sources, but beryllium observant pinch supplements because it’s easy to overdo it,” she adds.

Additionally, Amanda points to research2 that shows that nan carotenoids stored successful our tegument degrade aft having a acold aliases virus. “Levels besides driblet successful nan winter, apt owed to our little depletion of fruits and veggies, and possibly nan value is somewhat subpar owed to being retired of season,” she says. “For this reason, it's important to up your dosage successful nan cooler months to prolong nan benefits of carotenoids.”

2. Topically

A 2021 study3 recovered that applying carotenoids topically is an effective measurement to take sides against oxidative stress… conscionable not as effective arsenic consuming them orally.
