Collagen: Do you drink it? Inject it? Rub it on your skin? And does it work?

Collagen is a vital protein in the body, aiding skin plumpness and joint and bone strength. While there is anecdotal evidence of benefits from consuming collagen orally, experts remain skeptical about its efficacy. Collagen creams are unlikely to penetrate beyond the skin's outer layer. Marine collagen is recommended for oral consumption, while vegan options may be less effective. Overall, evidence supporting the substantial effects of collagen supplements on skin health remains inconclusive.
