If your skin looks dull, tired, or has lost its natural luster, you’re not alone. While high-end serums and creams can work wonders on the surface, real, lasting radiance starts from within.
The truth? No topical treatment can fully compensate for a nutritional gap in your body. If you want that “lit-from-within” glow, you need to feed your skin the right nutrients.
Here are the top 5 science-backed supplements that support hydrated, youthful, and vibrant skin—along with the best picks you can find on Amazon.
1. Vitamin C — The Brightening Powerhouse
