Topical Collagen and Derma Rolling?

[mykhel]

Is there any evidence that topical collagen creams-lotions are effective either by themselves or in conjunction with derma rolling?  I've read that the collagen molecules are too large to be adsorbed through the skin .  I was wondering if "science" has conquered this barrier, or if a  cream containing collagen can somehow be made effective when used  immediately before or after derma rolling?

Thank you. 

PS.  Sarah, this is a wonderful website, made all the more wonderful by your thoroughness and obvious integrity.  Thank you, again.

Thank your compliment on our website!

Dermal collagen is a huge molecule and it is not able to penetrate when topically applied. If you decide to apply it, do it after dermarolling. However, even if you manage to get it deeper into the skin with dermarolling or some new nano-method, this externally-supplied collagen will be eventually broken down and metabolized just like it happens with collagen injection fillers.

Dermaneedling will trigger production of your own collagen and that is the best.
Consuming collagen orally may be beneficial nevertheless there is no consensus concerning bioavailability of orally taken collagen.
