Collagen has quickly become one of the most talked-about beauty supplements on TikTok—and for good reason. Neuroscientist Robert Love recently broke down the science in a viral video, explaining how collagen supplementation can improve skin health and even reduce visible signs of aging.
In his breakdown, Love referenced a 2022 article published in Dermatology Practical & Conceptual titled “Collagen Supplements for Aging and Wrinkles.” The paper reviewed 12 clinical trials conducted between 2010 and 2020 that specifically examined collagen supplementation and its effects on skin.

What the Research Shows
“The evidence from the reviewed studies suggested that collagen supplements improve skin moisture, elasticity, and hydration when administered orally,” Love explained. But perhaps the most exciting finding? Researchers also discovered that collagen “reduces the wrinkling and roughness of the skin,” making it a powerful tool in any anti-aging regimen.
Why Collagen Declines With Age
Collagen is the most abundant protein in the body, responsible for keeping skin plump, smooth, and firm. Unfortunately, starting in your mid-20s, natural collagen production begins to decline—leading to fine lines, sagging, and loss of hydration. External factors such as sun exposure, poor diet, and stress can accelerate this breakdown, making supplementation even more valuable.
The Beauty Benefits of Collagen
Based on the reviewed studies, here’s what collagen supplements may help with:
- Improved skin hydration – reduces dryness and rough patches
- Enhanced elasticity – helps skin “bounce back” more easily
- Reduced fine lines and wrinkles – promotes a smoother complexion
- Overall skin texture improvements – leading to a youthful glow
Collagen comes in several forms, but the most common are powders, capsules, and ready-to-drink beverages. Many experts recommend hydrolyzed collagen peptides, as they are easier for the body to absorb. Consistency is key: most studies show visible benefits after 8–12 weeks of daily supplementation. You can add collagen powder to your morning coffee, smoothies, or even baked goods for an effortless beauty boost. Pairing collagen with vitamin C-rich foods (like oranges, bell peppers, or kiwis) can further support collagen synthesis in the body.
The Bottom Line
As Love explains, the science is clear: collagen supplementation doesn’t just live up to the hype—it’s backed by clinical research. By supporting hydration, elasticity, and reducing wrinkles, collagen can help keep your skin glowing and youthful for years to come. If you’ve been on the fence about adding it to your routine, this might be the sign your skin has been waiting for.
