Tretinoin (Original Retinoid) For Improvement Of An Indented Nose Scar?

I recently had a dermatologist prescribe Tretinoin 0.1 Retinoid Cream to me in an experimental effort to see whether it might help to improve the skin textural differences, and provide some slight improvements, for a notched and indented scar that is located at my upper nostril rim. The scarring itself is of the indented type but does not appear to be all that deep. Could the regular use of a collagen building retinoid, over time, truly provide any conservative improvements in this situation?
