Fraxel is one option in collagen induction therapies, which work by stimulating more collagen production in the body to rejuvenate the complexion. Microneedling is another. You can also combine microneedling with platelet-rich plasma (PRP) to further enhance the restorative process. Your age will not be as critical as the condition of your skin in determining the best treatment for you. I recommend an appointment with a board-certified plastic surgeon who can assess your skin and create a customized treatment plan for you.
Fraxel is a wonderful treatment that works on any age. Many of my Fraxel patients are ages 45+ and specifically use the treatment for age spots, pigmentation, and fine lines and wrinkles. You can get Fraxel at 90 if you want to, it is extremely beneficial, especially on aging skin.
