I remember reading awhile ago that injecting Hyaluronic Acid (HA) into a scar made it fade then come back, but injecting HA + CO2 made it go away. (https://pubmed.ncbi.nlm.nih.gov/37723352/). I think there's something about the combination that might be good even if you're not exactly dealing with scars. I'd look into carboxytherapy (it's a subcutaneous injection, but I think CO2 absorbs well enough through the skin even without that. there's little gels for a face mask you can get like from here
Otherwise I read that Vitamin A is needed in excreting calcium in the calcium cycle, so a topical vitamin A and D combo in coconut oil wouldn't hurt to try if you think calcification is involved.
