The argument for starting earlier is not that you need treatment younger. It is that maintaining something takes less intervention than rebuilding it.
Smaller inputs, spaced further apart
A preventative plan tends to mean conservative doses at longer intervals, aimed at holding a position rather than reversing one. It is also easier to stop, because there is less to unwind.
Skin quality before structure
Hydration, collagen stimulation and sun discipline do more over ten years than any single procedure. Treatments that work on the skin itself are usually the sensible first move.
Prevention is not a subscription
A good plan has review points where doing less, or nothing, is on the table. If every review concludes that you need more, that is worth noticing.
