Hmm, then we would also need to get hypnotised to do something about spots and scars, even though we can't see them on our faces.
Or, why not hypnotise all the rest of the people so that they not be able to see scars and spots on other people's faces?
I personally think it works better when we overcome the psychological impact of acne ourselves, in our own mind, realistically; then we can feel we have achieved something useful.
All the Best.
The above is only my Personal Humble Opinion, Folks.
I am no expert on these matters. Please consult the (supposed) experts, and seek the advice of other people as well.
