Is there any evidence that proves consuming collagen peptides can help with collagen production/skin health?

I've been using tretinoin for the past year and I've seen collagen peptides powder at the market a lot. I've heard how it's great to add to coffee and can help with improving skin texture (because collagen can't be absorbed topically, we have to eat it). This sounds like it would be perfect to combine with daily tretinoin.

I've also heard that it's broken down by the body and the amino acids are used wherever the they're needed, meaning not necessarily the skin. This makes it sound like an expensive subpar protein powder.

Is there any scientifically proven evidence that shows eating collagen peptides can help with anti-aging?
