Can dietary intake influence perception of and measured appearance? A systematic review.

Abstract in brief

• The review found that many studies show a link between what people eat and their skin appearance, such as skin color and signs of aging, with most research focusing on dietary supplements rather than real food.
• Evidence suggests that dietary improvements, especially through supplements, can positively impact perceived or actual skin features like wrinkles and elasticity, particularly in women.
• More high-quality research is needed, especially involving actual food intake (not just supplements), to better understand how diet influences appearance and to confirm these effects with reliable measurements.]
