Can I go deeper than 10 microns for microlaser peel for Asian skin?

I had microlaser peel done But after, I was told they can only go up to 10 microns deep on my skin because of the shade of my skin (I’m Fitzpatrick skin type 3 or 4). I’m disappointed. That’s the same depth as a microdermabrasion. I wanted a deeper resurfacing than a microdermabrasion. If this was the case then I wouldn’t have paid so much more for an MLP if I’m only getting a microdermabrasion result. Is this true? That MLP cannot go deeper for my Skin type?
