480cc & 520cc Boost Mentor high profile 6 months ago, when do they soften?

I had mentor memory gel for 20 years, then removed implants for 10 months, had new BOOST high profile 480 put in. It’s been 6 months … when do they soften?! It’s hard to lay on my stomach, they have softened some but not much. I had to do the z wave to get the left one to drop and it’s still high. Quasi double bubble but regardless of that I feel they should be softer at this point. My fear is that the implant type itself is more firm. I am 5’1 and 110lbs implant 480 R side and 520 left side
