No, I'm afraid there is no substance that has been demonstrated to stimulate collagen production as an ingredient in a topical cream.
There are complex chemical compounds that have been shown in many in vitro studies and some in vivo studies to potentially stimulate collagen production, but these substances are extremely expensive and there are great technical difficulties in making them available in a cream formulation. Unfortunately, most of the claims made for these creams are based upon these studies.
The cosmetic industry has a reputation for not being as rigorous in respect of R&D as other industries and they do tend to latch on to any piece of research in other industries that will give credence to their often outlandish theories. As a result, beauty products are frequently marketed with very little scientific fact in their support.
