According to WebMD, collagen is a protein vital for the proper functioning of our connective tissues, and it is the connective tissues that "give your body shape." Collagen keeps our skin firm, which is why our skin tends to sag as we age, per Byrdie. Instead of collagen creams, board-certified dermatologist Marie Hayag recommends adding retinol or peptides to skincare to boost collagen production and sunscreen to "prevent your collagen from breaking down" more. The best source for collagen is animal products like skin, joints, and ligaments, per Healthline.

If you eat an adequate amount of protein like poultry, beans, and fish, you should be good. Bone broth is an excellent source of collagen also. However, if that's not your thing, there are other delicious ways to add collagen supplements into your everyday diet.
