Retin A (tretinoin) : Is best as it promotes fibroblasts which lay down collagen.

Growth factors: We have known since the 70s that retinoids and retinols are great collagen stimulators (which equals wrinkle fighters). In this century, we developed collagen growth factors which are derived from actual human skin and are necessary for collagen to thrive, thus reducing and eliminating wrinkles. Note i did not say "appearance of wrinkles". Skinmedica is my favorite product to contain these.
