Sardine trend boosts sales online

A new skincare trend, dubbed the "sardine glow," has gained traction on social media platforms like Instagram and TikTok. The trend suggests that eating sardines can improve skin radiance, leading to increased sales of sardines in retail stores and some products running out of stock.

Influencer promotes sardine benefits

TikTok influencer Diane Skincare, who has 3,200 followers, has posted multiple videos promoting the health benefits of sardines. She highlights their omega-3 content as a key factor in achieving a glowing complexion, contributing to the trend's popularity.

Dietitian explains sardine benefits

Sandra Ferreira, a dietitian-nutritionist, explains that sardines contain long-chain omega-3s (EPA and DHA), which support skin cell function and reduce inflammation. They also provide proteins rich in amino acids that aid in skin renewal. However, she cautions against calling sardines a "natural botox" or miracle food.

Sardines not a substitute for skincare

Ferreira emphasizes that while sardines contribute to skin health, they are not a cosmetic product or a replacement for medical treatment. She notes that skin health is influenced by factors such as genetics, sun exposure, sleep, and stress, and that no single food can replace proper skincare or medical advice.

Experts recommend balanced fish intake

According to the National Agency for Food Safety (Anses), consuming fish twice a week, including fatty varieties like sardines, salmon, mackerel, and herring, is recommended. A reasonable weekly intake is around two portions of 100 g each.

Sardine sales rise among younger consumers

Sales of sardines have increased by 7% since the start of 2026, with a 27% rise among those under 35, according to a report from Le Monde published on October 18. Ferreira advises consuming a variety of fish to avoid excessive exposure to contaminants while still benefiting from their omega-3 content.
