When Does Aging Really Begin?

Uncover the real timeline of aging — and what to do before the signs appear.


Your Skin Has a Clock — And It Starts Sooner Than You Think

Most people think aging starts in their 40s — but biologically, it begins much earlier. By your mid-20s, collagen production already starts to slow, and subtle changes begin in the deeper layers of your skin before you ever see a wrinkle.

Key Stats:

  • Collagen production declines ~1% every year after age 25
  • Elastin production essentially stops after puberty
  • Skin hydration and cell turnover begin to drop by age 30

This means preventative care isn’t a luxury — it’s the key to long-term youthfulness.
