Anti-aging efficacy: Science vs. hype in supplements and skincare

The longevity and anti-aging market is seeing significant growth, though scientific evidence for many popular products remains limited. Research into taurine, once thought to extend lifespan based on studies in mice and worms, has faced more complex findings in human studies published in the journal Science.

Dermatologists note that while collagen powders are popular, there is a lack of long-term clinical studies proving they effectively build human collagen after digestion. Instead, experts recommend proven topical ingredients like retinol, which stimulates collagen production and cell renewal. Combinations such as retinol and bakuchiol are noted for their effectiveness, particularly for sensitive skin.

Product testing of anti-wrinkle creams shows that high-quality ingredients—including retinoids, Vitamin C, and peptides—are essential for efficacy. Some consumer tests indicate that more expensive products often provide better results than cheaper alternatives, with certain popular brands failing to show significant active anti-wrinkle effects.
