I had 2 TCA cross treatments with a dermatologist and between the cost and getting out to his office (which required me to rent a car) and cost of the treatment, I decided to do a cross treatment myself.
I had trouble ordering a pre-made 100%tca solution, and I was also learly of ordering it online in case the quality wasnt reliable. So I made my own. I ordered pure ACS Reagent TCA crystals (this is very important...since the purity and high grade of the crystals is essential), bought a sensitive small weigh scale at the science store (which can weigh fractions of a gram), and dissolved 9.41grams of the crystals in 10ml of pure steam distilled water.
This gave me some wiggle room for a solution between 90-100% pure tca.
I store the crystals in their jar inside a freezer bag in the freezer. I have enough to treat myself and probably 100 other people for years! All of this (including the scale, small beaker, dark glass storage container for the mixed solution, and glass stir stick) for much less than the price of a single visit to the dermatologist!
I did my first treatment on myself 3 days ago, using a wooden toothpick. I sharpened the tip a little and it was the perfect size. I'm a little nervous that I used too much of the solution in a couple of small spots (since being more conservative is better than not when applying TCA), but overall things look good so far. I am keeping all treated areas coated in Vaseline for a full week, possibly even 9 days depending on how things look in a few days.
Unfortunately I did not take before photos. The icepick scars are mostly on and beside my nose. They have always really bothered me, so I am very anxious to see the results. But the full results won't be fully realized for another 4 months.
