Most people won’t bother to do proper research and actually understand how can it “theoretically” work, for most people doing a conservative amount of filler it’s the best option, way more convenient for people who are not willing to have to deal with the sides of Winstrol or any other steroids that supercharges collagen synthesis, also learning to DIY fillers is not that hard, orka, dior, veridic and other users have managed to do this without any issues, and the migration risk is low when the supraperiosteal injection is done properly, also HA fillers are relatively cheap, 60$ plus the needles and syringes, the numbing cream and if u fucked yourself the hyaluronidase, ofc fillers are not a long term solution, but you could probably get some good results injecting and after 12 months dissolving and repeating, till you manage to get the money for implants ofc.
