Period
March – June 2026
Observation log
Week 1–2
Nothing visible. No reaction.
No change in line depth or skin density in the photographs. No stinging, flushing or flaking at any point. Client reported only that her skin felt more hydrated.
Week 4–8
Fine lines begin to fade. Skin density increased.
The fine, fanned lining around the eyes and around the mouth was measurably less. Skin over the cheekbones and orbital area was palpably thicker and better supported than at intake. The forehead were unchanged, as anticipated; these are muscle-driven and outside what this protocol addresses.
week 4
Week 8
Week 8–12
The result held with nothing on the skin.
The crepey texture recorded beneath the eyes and along the upper cheeks were no longer present at rest, and lines that had previously remained visible with the face relaxed were no longer distinguishable at conversational distance. Skin was appreciably denser and more resilient on palpation than in week 8, consistent with structural change rather than surface hydration. Expression lines on movement were unchanged throughout, as anticipated.
