Ask Your Pharmacist: Should You Be Taking Collagen as Part of Your Skincare Routine?
A pharmacist breaks down what collagen really does for your skin, and what the science says about it.
The Question
My Dad recently asked if there is anything he could take to improve his skin. Naturally, the first thing I did, was go down the collagen rabbit hole because this question comes up a lot, especially as we age.
So What is Collagen Anyway?
Collagen peptides or hydrolyzed collagen are tiny pieces of protein that come from animal collagen. They are the main protein that gives structure to your skin, joints, and bones. These small peptides are what most supplements use, because they’re easier for your body to absorb.
Cautionary tip: Collagen peptides are not to be confused with Native Collagen Type I and Native Collagen Type II, which have longer collagen peptides and different uses.
How Does it Work?
When taken by mouth, collagen peptides seem to build up in the skin and cartilage, where they may help improve some skin and joint conditions.
Topical collagen, on the other hand, has limited scientific backing; current studies are small and inconclusive. While it may hydrate the surface temporarily, evidence for deeper or long-term skin benefits is still minimal. There’s definitely more research to be done!
What is it Used For?
Collagen peptides are used for dry skin and aging skin. They are also used for brittle nails, muscle strength, and many other purposes.
So, What is the Truth? What Does the Evidence Say?
For Aging Skin
Research suggests that taking collagen peptides orally can help improve skin hydration and elasticity as we age. Some studies also show a modest reduction in fine lines and wrinkles, though results may vary, and the visible difference isn’t always dramatic.
Multiple studies and comprehensive reviews have found that collagen peptide supplements can enhance skin hydration and elasticity.
Collagen Source Matters: The source matters when choosing which Collagen may be right for you. One study found that Collagen derived from fish was shown to support both skin hydration and elasticity, and Chicken-based collagen peptides appear to offer a mild boost in elasticity, though they have little effect on hydration. Meanwhile, bovine-sourced collagen has not consistently shown measurable improvements in either hydration or elasticity.
“As always, whole food sources should come first before adding supplements. One of the best natural sources of collagen peptides is homemade bone broth, especially when made from fish or chicken bones.”
When to Consider a Collagen Supplement
While whole foods should always come first, supplements can be a practical option if you:
Don’t regularly eat collagen-rich foods like fish skin or bone broth
Have increased skin or joint needs due to aging, hormonal changes, or high physical activity
Want a more consistent daily dose for visible results
Collagen supplements come in powders, capsules, or liquids, but not all are created equal. The best formulas are hydrolyzed collagen peptides that list their source (fish, bovine, or chicken).
