Protocol
YURSLF PDRN · Daily
Documented by
F. Karfell, Medical Aesthetician
Period
March – June 2026
Observation log
Week 1–2
Nothing visible. No reaction.
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 fine, papery roughness recorded along the cheeks and perinasal area at intake was no longer palpable at the week 6 assessment and did not return. Skin was measurably more cushioned under the fingers and restored hydration in the deeper layers rather than surface polishing.
week 4
Week 8
Week 8–12
The result held with nothing on the skin.
Hydration and surface plumpness were retained at each check. The skin surface was even enough to reflect light uniformly across the cheeks rather than scattering it. No lightening of pigment was observed or expected. Skin read as fuller and more cushioned on palpation than in week 8.
