Are Laser Treatments Preventative or Should I Wait?

You're already engaged in one excellent practice of using a retinoid for cell turnover. And sun protection is also a great prevention tool (Anyone who compares buttock skin to arm skin can clearly see what the sun can do to you!)

Heat based treatments are a nice way to keep the collagen cycle going. Collagen production naturally slows down and collagen degradation speeds up as we age. Intervening along the way prevents having to deal with bigger issues later.

Fractional lasers like Fraxel keep the collagen factory operating well - but anyone with moderate to high levels of pigment need to be careful. Fractional radio frequency like eMatrix is more specific to skin that has higher levels of pigment.

Chemical peels can be helpful too, but work generally at a much more superficial level.

Non-ablative treatments such as IPL or Clear+Brilliant laser will stimulate collagen, make your skin radiant and slow down aging.  Continue with your retinoid and sun protection and use topical antioxidants such as vitamin C.  Consult a dermatologist who offers laser treatments and can assess your skin and formulate a program of treatments for you.
