Hello and merry Christmas to everybody.

The topic is not entirely new, I am aware of that

I am asking if someone figured out a dosage equivalnce between Vitamin A and Isotretinoin.

Let me explain.

I am aware that they are not at all equivalent things.

In any case they have a thing in common which is the capability to reduce the sebum excretion rate.

So with reference to this specific action one can make a comparison.

In technical terms the question is how many IU of VitA / kg of body weight equal 1mg Isotretinoin / kg of body weight in terms of sebum reduction ?

Please refrain from warning me about the risks of Vitamin A on the liver.

It is obvious that if the answer to the question brings about a toxic dosage of Vitamin A, one should not take such a regimen.

Just focus on the very specific question of the topic, even if it might seem merely theoretical.

Thank u.
