What can happen quickly is a change in hydration, skin-barrier health, inflammation, sun exposure, stress, sleep, skincare habits, hormones, or environmental conditions that suddenly makes existing signs of aging much more visible. And sometimes, what looks like “sudden aging” is actually your skin telling you that your current routine isn't giving it what it needs anymore.

While the name may sound like another social media buzzword, the concept is rooted in real skin biology: stimulating and protecting your skin's collagen before significant signs of aging appear. Experts generally agree that while you can't literally "store" collagen, you can consistently encourage collagen production and slow its breakdown through proven treatments and healthy habits.
