For magnificence and trend influencer Toni Bravo, the key to glowy pores and skin isn’t a Ok-beauty serum or a triple-digit skincare machine — it’s a tin of sardines.
“Everybody desires a skincare routine till I convey up sardines. Would you like it or not?” Bravo mentioned in a Feb. 10 TikTok to her 930,700 followers. “I’ve eaten sardines my whole life … so I’ve identified the facility, the wonder that’s fish.”
The idea of “consuming your skincare”— particularly fatty fish like tinned sardines, salmon and mackerel — isn’t new. Lengthy embraced in wellness circles as a type of “nature’s Botox,” sardines are wealthy in omega-3 fatty acids, high-quality protein, calcium, nutritional vitamins, selenium and iron. They’ve been linked to enhancing pores and skin barrier operate and decreasing inflammatory responses, each of which might contribute to healthier-looking pores and skin over time.
However the development has as soon as once more taken maintain on TikTok, the place customers are experimenting with “sardine diets” for every thing from weight reduction to clearer pores and skin, whereas others are merely including the salty snack to their routines after seeing the outcomes — or not less than the promise of them — on Bravo and different influencers.
“Ms. Toni Bravo has single-handedly satisfied me to strive a can of sardines,” one person mentioned on TikTok earlier than attempting sardines for the primary time. In one other video, a TikToker mentioned that when she discovered that Bravo’s factor was sardines, she thought, “It’s going to be my factor now too.”
“When my pores and skin begins breaking out or wanting uninteresting … I eat sardines as a result of clear pores and skin begins from inside,” one other person wrote in a video.
Specialists say that sardines are undeniably nutrient-dense and have lengthy been linked to general well being and hydration, in addition to to sustaining an anti-inflammatory stability and supporting pores and skin boundaries. However the fatty fish is just not the skincare and weight-loss savior some influencers recommend.
“The draw back is that canned sardines could be excessive in sodium, and a few folks might not tolerate them nicely on account of reflux, migraines triggered by histamines, or just style choice,” Amy Goodson, a registered dietitian, advised NBC Information. “So nutritionally they’re nice — however they aren’t a ‘magic’ meals, and so they don’t work for everybody.”

Dr. William Li, a doctor and scientist who focuses on the connection between well being and meals, additionally famous that there’s “no historical past of sardines as a meals for pores and skin magnificence” — simply the omega-3s the tiny fish are filled with.

“Human research present these omega-3s scale back inflammatory biomarkers and are protecting in opposition to oxidative stress and cell harm,” Li mentioned. “Omega3: additionally helps vascular well being, which is essential for pores and skin well being,” he added.
That’s the place the TikTok narrative concerning the “sardine weight loss program” and even “sardine quick” hit a dietary wall.
The viral dietary quick, which is so simple as consuming solely sardines for a set interval, guarantees to assist with pores and skin points, fats loss and decrease blood sugar. Dr. Annette Bosworth, an American doctor often called “Dr. Boz” on TikTok who focuses on metabolic well being, even referred to as it a fast technique to increase blood ketone ranges — a chemical the physique produces when it burns fats for vitality as an alternative of carbs.
“You can’t ‘detox,’ reset hormones, or dramatically remodel pores and skin from one meals in a number of days,” Goodson mentioned. “Pores and skin modifications usually happen over weeks to months, not days, and so they rely upon whole way of life — weight loss program high quality, sleep, hydration, stress, and solar publicity.”
As an alternative, specialists agree that sardines needs to be handled as a wise add-on to a broader weight loss program, comparable to including them to salads or on high of avocado toast, and that limiting them to a single meals may even have antagonistic results.
The web, nonetheless, nonetheless can’t appear to get away from the reasonably priced salty tinned fish.
