My daughter took accutane. It cleared her skin beautifully, but she still has side effects 10 years later, but not bad.. mostly dry eyes and nose. She’s now 26. My sister , who is 62 did it about 3 times I think.
I think accutane works by reducing the parathyroid hormone.
One can reduce the parathyroid hormone by
having a good level of vitamin d
sun exposure
consumption of potassium and calcium
if one has excess retinol, reducing it. drinking beer, yogurt, smoking cigarretes and sun exposure reduce it.
