A member asked:

Collagen topical how often do u use on face weekly/ daily?

A doctor has provided 1 answer

Collagen...: ...In a topical preparation does not actually penetrate the skin; other ingredients (glycerine, lanolin, mineral oil, etc) have more effect on the skin, and it is they that determine how often you can use it, so you need to look at the actual label for instructions.
