Other treatments available for SP.

All will need doctors referrals, and the more efficient they become, the harder these treatments are to receive - money wise.

DO NOT  use TCA Chemical Peels.
Putting acid on your penis is never a good idea, and this will only lead to a temporary fix, severe infections, and intense scarring which will look A LOT worse than my day two picture for several months. Costs $30-$250
You may / may not need a referral to a skin doctor, if your GP is prepared to perform this.
However I do not encourage getting this in the slightest.
STAY. AWAY.

Hyfraction, electrolysis, (or anything else with electro in the name)
Cost: $25 - 150
This is what I am having performed, painful without anesthetic, worth every cent, inexpensive.
You will need a referal from a doctor to a dermatologist to have this performed.

Co2 Laser Treatment:
Cost: Upwards of $175
There has been reported success, but there are also reports of this treatment not lasting, this is where a laser burns the skin and glans, in an attempt to destroy the follicle.
Leaves extremely visible scarring.

Pulse Die laser treatment:
Cost: upwards of $200 per session - usually up to 5 sessions required (depending on seriousness of your condition)
This will work every time guaranteed, but is very expensive, you will need a referral from your dermatologist to a cosmetic surgeon to have this performed, and it is not widely available, if you are able to get this done and have the money to spare.
Do it.
