Hi,
Scar remodeling and collagen stimulating procedures as listed by you will work just as well in older and more mature patients.
In addition, older patients undergoing such resurfacing procedures will benefit from improvement in fine lines, skin clarity and reduction of superficial pigmentation such as age spots.
A personal assessment and thorough discussion with your preferred aesthetic doctor will help determine which of the available procedures will best address your key concerns and which combination will best help you achieve your expected treatment outcomes.
Hope this helps!
