Collagen has quickly become one of the most talked-about supplements in the wellness world—but does it actually live up to the hype, especially after 40? According to Dr. Asif Ahmed, the answer isn’t so simple. While emerging research shows promising benefits for both skin and joints, there are also important factors to consider before adding it to your routine.
Here’s what the science—and Dr. Ahmed—say:

It May Improve Skin Elasticity and Reduce Wrinkles
As collagen production naturally declines with age, many people turn to supplements in hopes of maintaining a youthful appearance. And according to Dr. Ahmed, there is growing evidence to support this.
Several large studies, including systematic reviews analyzing hundreds to over 1,700 participants, found that collagen supplementation can improve skin elasticity, boost hydration, and even reduce the appearance of wrinkles. Some results were shown to last up to 30 days after stopping the supplement.
This suggests that collagen may help strengthen the skin’s structure from within—making it appear smoother and more resilient over time.
It Could Support Joint Health
Collagen isn’t just about skin—it also plays a key role in joint function. As we age, cartilage naturally breaks down, which can lead to stiffness and discomfort.
Dr. Ahmed points to research on hydrolyzed collagen, which contains smaller peptides that may reach joint tissues more easily. In studies involving people with osteoarthritis, these peptides were shown to help protect cartilage and support joint health.
For adults over 40, this could mean improved mobility and less joint discomfort—especially when combined with other healthy lifestyle habits.
Safety Concerns to Keep in Mind
While the benefits are promising, Dr. Ahmed emphasizes that not all collagen supplements are created equal. One major concern is quality control.
Some investigations into supplement brands have found traces of heavy metals like arsenic, lead, and mercury. While small amounts can exist naturally in foods, the lack of strict regulation in the supplement industry means levels can vary—and consumers may not always know what they’re getting.
That’s why Dr. Ahmed stresses the importance of choosing products that undergo third-party testing to ensure purity and safety.
Collagen supplements may offer real benefits for skin and joint health—especially after 40—but they’re not a miracle fix. Consistency, quality, and overall lifestyle all play a role.
If you’re considering adding collagen to your routine, the key takeaway is simple: do your research, prioritize high-quality products, and view it as one piece of a broader approach to healthy aging.
