Context after the answer

Why this structure works

The useful part of a protocol is the dose you can repeat. This version deliberately starts conservatively, gives you a clear stopping rule, and leaves room to progress only after the routine feels stable.

Evidence labels describe the body of research behind the broad practice—not a promise that every person will get the same result. Where research is observational, indirect, or limited to a specific population, we treat that as a constraint rather than filling the gap with certainty.

Safety note

Know when the protocol is not the move.

Do not look directly at the sun. Follow professional advice for eye conditions or medicines that increase light sensitivity.
