Is there a specific target audience for anti-aging treatments?

Now that I've passed my mid-thirties, wrinkles are starting to appear one by one, so I've become interested in anti-aging treatments. By any chance, what is the typical age range recommended for anti-aging procedures? I'm worried that starting too early might render them ineffective later on, so I'm wondering if I should start taking care of myself now.

I've heard that it's best to get anti-aging treatments as a preventative measure. Is the answer to tighten my skin before it sags further? I'm curious at what age you usually start serious lifting or skincare treatments. I feel like I need to hurry up and do something before my wrinkles get too deep.

I really want to get an anti-aging treatment before it's too late. Please help me.
