Lingonberry is packed with phenolic compounds (natural plant chemicals) that showed antimicrobial, anti-inflammatory, and antioxidant properties in lab and some human studies. When fermented, lingonberries appear to support healthier skin microbiome by encouraging good bacteria growth. However, the researchers are honest: most evidence is from lab work, and we need way more actual human studies before we can make real claims about skin benefits.

This is a review paper that analyzed existing research on lingonberries—both lab studies using human cells and actual human trials. The authors looked at whole berries, juices, and isolated compounds to see what the science actually shows.
