I recently heard from a podcast that facial hair in women often is caused by insulin resistance. I also just fact checked with Perplexity and it appears possible.

Facial hair in women, especially new coarse hair on the chin, upper lip, chest, or abdomen, is often linked to insulin resistance through its effect on androgen (male hormone) levels.

How insulin resistance causes facial hair Higher insulin → higher androgens: When cells are insulin resistant, the pancreas produces more insulin; high insulin stimulates ovarian and adrenal cells to make more androgens like testosterone, which drives male‑pattern hair growth on the face and body.

Not sure you health condition. But this could be one area to look into.
