You know the saying: Good things take time. Unfortunately in the skin care world, we often forget that simple fact—and demand a flawless appearance mere days (or hours!) after starting a new routine. Now, this is partially the industry and media's fault: Our relentless messaging about how "This magical find can fix all your problems overnight!" has given unrealistic expectations to consumers. 

Honestly, that's unfortunate: Because when people stick to routines, with consistency and care, actual skin care wonders can happen. The best beauty routine is one you'll actually do. Now, this is true of all products—like topicals and tools—but is especially the case with supplements. 

When you start a new supplement regimen, it's vital to know the time frame in which you should expect to see results—especially when your new supplement du jour is a much-buzzed-about item. And what skin care supplement is more buzzy nowadays than collagen, no?* 

How long it takes to see changes in the skin during a collagen regimen. 

The way we come to a conclusion about how fast a supplement works is through studies. In clinical trials, researchers are able to keep track of changes in the body and skin to evaluate what's happening and when. 

Skin care supplement clinicals usually span several months: Within this time frame, we're usually able to see if something is effective—and to what extent.* See, your epidermis renews itself every 46 to 50 days1 through a process called desquamation, so within three months, you should be able to see how the new skin cells being generated respond to the new routine. Many people say this process happens every 30 days, but that's been proved to be a misconception. 

For skin benefits, 12 weeks (i.e., three months) is a common duration in which you can see full results according to robustly designed research. For example, this 12-week study found that the patients taking a collagen supplement experienced enhanced skin elasticity, hydration, and density2.* Another found that respondents experienced smoother skin texture3.* This additional study measured skin-related outcomes (such as hydration, elasticity, and wrinkles) at both six and 12 weeks, with significant results4 at the latter duration.* 

Some studies suggest you may be able to see results sooner. This research investigation reported statistically significant skin elasticity enhancement5 at four weeks.* Another suggests that results were even greater at eight weeks6.* Finally, this clinical trial measured skin markers at two, four, six, and eight weeks—with noticeable results at six and eight weeks7 but not before.*  

Essentially, the scientific evidence to date indicates you may see improvements within the second month of use, but for full results, you should stick with it until at least three months. 

The takeaway.

Achieving your healthiest skin is about consistency—and this is vitally important in the case of supplements. If you are diligent with your intake, you'll reap the benefits: Just give it enough time to work properly.*
