Duration of acne scar treatment that firmly fills indented marks

The spots on my cheeks where I had forcefully squeezed out pustular blemishes with my hands in the past have become deeply indented, resulting in an unsightly skin texture resembling an orange peel.
I get tired and have reached my limit every morning of filling in my blemishes with primer and pot concealer, so I am looking for information on dermatological acne scar treatments like Fraxel or Subcision.
I heard that the principle is to shave off the skin with a laser to make new skin grow, but I suddenly wonder how long the skin that grows back after all that effort will last.
I would like to know in detail and accurately about the duration of acne scar treatment results, specifically whether the scar area will sink in again as time passes and I get older.
Given that I endured excruciating pain that brought me to tears and spent a lot of money, I have a very strong desire for the acne scar treatment to be permanent and last a lifetime.
For those in the community who suffered through acne scar treatments a long time ago, are you still maintaining smooth, firm skin without any pitting even now, several years later?
I would also like to hear the opinions of experts or those with experience on whether applying a generous amount of expensive regenerating cream and performing thorough home care after the procedure can keep the smooth effect as if it were my own skin for a lifetime.
Even though the downtime is long and I have to wear a mask for a long time in the middle of summer, I am going to summon a huge courage this time for smooth skin, which has been my lifelong dream.
I earnestly request honest and candid factual feedback regarding the meticulous post-procedure regeneration care and the firm retention of the plumped-up skin.
I want to completely break free from the deep frustration I feel every time I look in the mirror with my makeup off, and go around confidently and proudly with a bare face.
