Collagen, skin and GHK-Cu: the reading list

Starting points

For the cellular starting point, the human fibroblast collagen experiment would be my first stop. The tissue-remodeling review widens the account to repair across the work it reviews.

The review of topical GHK addresses the delivery problem. Beside it sits the human skin penetration experiment, where copper was measured in skin outside the body.

For a controlled human experiment, there is the combination hair trial. The gene-data review moves to a much wider scale, and rewards attention to the threshold attached to its headline figure.
