Fine Lines: Prevention Beats Treatment
Only three ingredients have solid scientific backing against visible aging.
What causes lines
Collagen loss starts around age 25 at roughly 1% a year, accelerated by sun, smoking, excess sugar, and poor sleep.
Ingredients with real evidence
- Retinoids: the strongest evidence for collagen stimulation.
- Vitamin C: protects existing collagen and supports its synthesis.
- Sunscreen: prevents the damage in the first place — the most important of the three.
Habits that matter
Sleeping on your back reduces compression lines, hydration softens surface lines immediately, and quitting smoking halts an ongoing decline.
