There is hope, thanks to Sarah. I have been doing the subcision procedure on myself with good success- the improvements are incremental and steady. (Living in the states, it was difficult to find a supplier of sterile, injectable saline and 28 gauge syringes, but I eventually found I can get them on-line from Allegra Medical, no questions asked.)
I never use the same syringe twice during one session of subcision, so I go through several syringes every 3 wks but they, and the saline, are inexpensive. I have been needling using dermal stamp, and rolling my face with a 2mm roller every 6 wks, and performing subcision every 3 wks, so that every 6 wks I am combining the rolling and stamping session with needling and subcision. I have had no problems, which may be because I use very good aseptic technique, washing everything down with alcohol before starting the procedure, filling the syringes using sterile technique, and cleaning my face and hands repeatedly with alcohol before each injection. I must admit, it takes some bravery to do this to one's self, and I say this as a RN, but it can be done. I have decided to pull out my 1.5 mm roller, which can be used every 3-4 wks, and start doing the entire combined procedure every 3 wks just to push it along a little faster.
Also, I love Alcare Plus, which can be bought on-line- I rub it into my skin many times per day on the days after I roll. It is an alcohol foam product used in hospitals to cut down on staph infections- it has an emollient which keeps the skin from drying out.
I am so empathic with anyone who struggles with acne scarring, having lived with it for 44 yrs before I started working with Sarah and her products, so I hope this advice will be helpful. Sarah is a gift from above!
P.S. I feel I actually "hear" the scar tissue releasing most when I am using the dermal stamp, which I do 6-8 times per scar each session, rotating the stamp slightly clock-wise after each punch. (My advice is to repeatedly clean the skin with alcohol soaked cotton balls throughout the procedures. I do not know if everyone agrees with that, but it works for me.)
