Somewhere in the last year, the produce aisle has made several attempts to annex the skincare section. Scroll Tiktok long enough and you’ll find carrot salads captioned like serums, bone broth made for the same purpose as a nightly retinol, and more than one creator eating tinned sardines for breakfast like it’s a light facial treatment.
The trend has a name: eating your skincare. And a founding text: a shredded carrot salad from creator Lainie Kates, tossed with sesame oil and lime, that racked up nearly a million views on the promise that beta-carotene could do from the inside what a serum does from the outside.
It’s a creative idea, and creative ideas move fast online. It’s also, like most things that move fast online, a little bit exaggerative. The more useful version of this story, and I’d argue the more interesting one, is about something we’ve been avoiding: a good deal of what we’ve outsourced to topical treatments could’ve been accomplished from the inside out.
THE PART THAT’S TRUE ABOUT SKIN & FOOD
Skin is an organ, and organs are downstream of what you feed them. This isn’t a Tiktok discovery; dermatologists have been saying it for decades with considerably less enthusiasm for lighting.
Vitamin C is a cofactor in collagen synthesis. No vitamin C, no collagen, regardless of how much peptide serum you’re layering on top. Omega-3s, the kind found generously in sardines and other oily fish, support the skin’s integrity and have a real, published relationship with inflammation.
Leafy greens and berries bring antioxidants that help offset the oxidative stress your skin racks up simply by existing in sunlight and city air. Collagen peptides (the whole premise behind the bone broth moment) show modest but real evidence for skin elasticity in some studies.
None of this is new information. What’s new is the framing: instead of “eat vegetables, it’s good for you,” it’s “eat this specific salad, it’s your retinol.” The rebrand works because it borrows skincare’s promise of control – the idea that a routine, precisely followed, produces a guaranteed result – and applies it to food, which has never once in human history behaved that predictably.
THE PART THAT’S MORE COMPLICATED
Where the trend gets a little ahead of itself is in the promise of speed. Nutritionists who’ve actually studied this are consistent on one point: diet affects skin gradually, through habits repeated over months, not through any one hero food eaten with enough conviction.
Which is, in its own way, good news. It means you don’t need a perfect plate. You just need a fridge that’s stocked with a few of the right things, most of the time.
HOW TO ACTUALLY EAT YOUR SKINCARE
The best version of “eating your skincare” isn’t a hack. It’s just cooking well, on purpose, with your skin as one beneficiary among several. Consider it less a regimen and more a standing grocery list – the well-known staples, plus a few the algorithm hasn’t fully caught onto yet.
Something orange. Carrots, sweet potato, pumpkin. Beta-carotene converts to vitamin A, which supports cell turnover. Roast them with olive oil; fat helps you absorb it.
Something oily and finned. Sardines, salmon, mackerel, twice a week, is a real and unglamorous habit with real and moderate benefits.
Something bitter and green. Spinach, arugula, kale; folate, vitamin C, lutein. Dress it up; bitterness improves with a good vinaigrette.
Something with collagen. Bone broth as a base for soup, or stirred into rice. Treat it as a cooking ingredient, not a supplement regimen, and you’ll actually keep doing it.
Something red and cooked, not raw. This is the one nobody talks about: lycopene, the antioxidant that gives tomatoes their color, becomes more bioavailable once cooked, not less. A slow-simmered tomato sauce with olive oil does more for your skin’s natural resilience against UV stress than the same tomato eaten raw in a salad.
Something fermented. Yogurt, kimchi, a good miso. The gut-skin axis is one of the more legitimately exciting areas of current research. A balanced gut microbiome is increasingly linked to less inflammation showing up on the surface.
Something small. Pumpkin seeds, sunflower seeds, a spoon of tahini. Zinc gets almost none of the attention niacinamide does, despite doing adjacent work; regulating oil production and supporting the skin’s repair process from the inside.
Water, before the serum. The most unglamorous fact in all of this: dehydrated skin looks dull no matter what you eat or apply. Consistent hydration and electrolytes matter more on a hot day than any single skin food ever will.
None of this replaces sunscreen. None of it replaces a dermatologist if something’s actually wrong. What it replaces is the exhausting idea that your face is a project requiring twelve steps and a shelf of serums to maintain. When sometimes it’s just asking you to eat like someone who plans to enjoy being in this body for a while, and let the glow be a side effect, rather than the whole point.
