What This Study Did, in Plain Language
What Was Tested
Researchers studied Copper (Supplement) in this randomized controlled trial publication.
Chronic exposure to the sun causes the skin to prematurely age.
Photodamaged skin is characterized by progressive damage to the dermal extracellular matrix with loss of collagen and degradation of elastin.
Who Took Part
PubMed indexes the participants as adults, middle-aged adults and older adults, women only.
Clinical assessments were performed at screening/baseline and at week 8.
Standardized digital photographs were taken and self-assessment questionnaires were conducted.
How the Study Was Run
The design is described as randomized, double-blind and pilot.
The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.
Neither the participants nor the staff measuring them knew who was on Copper (Supplement), so expectations could not easily colour the readings.
It is described as a pilot, a small early test of whether a larger Copper (Supplement) study would be practical.
What Was Measured
Salts of copper chlorophyllin complex are semi-synthetic naturally derived compounds with anti-oxidant and wound healing activity that has not been previously tested in photodamaged skin.
Topics PubMed links to this paper include Administration, Topical, Chlorophyllides, Dermatologic Agents, Face, Pilot Projects, Radiation-Protective Agents and Self-Assessment.

Our Notes on the Compound
Copper (Supplement): The active site of cytochrome c oxidase is described as containing copper ions that are essential for electron transfer.
