F. Karfell, Medical Aesthetician
Period
March – June 2026
Observation log
Week 1–2
Nothing visible. All exfoliation withdrawn
No change in the photographs. No stinging, flushing or purge at any point. Client reported only that her skin felt more hydrated.
Week 4–8
Dry patches resolved and the grey cast lifted.
The recurring dry areas along her cheeks and around her mouth did not return, and the dull tone recorded at intake had lifted. On assessment the skin was firmer and more cushioned under the fingers.
week 4
Week 8
Week 8–12
The result held with nothing on the skin.
Hydration and surface plumpness were retained at each check, indicating the result was no longer dependent on product. Tone remained even across the cheeks with no recurrence of the dry areas. Skin felt appreciably thicker and more resilient compared in week 8.
