Nutrition is a core component of overall health and has an indirect link to skin appearance. Skin is the body's largest organ and is affected by general health. A balanced, varied diet supports overall health, including the skin.
Water intake, a diet rich in fruit and vegetables, and balanced healthy fats are generally recommended as part of a healthy lifestyle. But avoid absolute, exaggerated claims like "this food beautifies skin" — appearance is affected by many combined factors.
Skincare and nutrition complement each other; neither replaces the other. Barrier-friendly care from outside, balanced nutrition from within, and general healthy living form a whole. For specific nutrition questions, consult a physician or dietitian.
