Hi Stephh,
Obviously I'm not Sarah but I've came across your post a couple of times while I was as you call it "lurking" on this forum as well. LoL. Just like you, I've started to take serious steps to improve the scarring that was left from my many years of acne. I've been left with some mild to moderate scars on my upper cheeks that sounds like they could be similar to yours. Straight on the scars aren't that noticeable but at an angle and in certain lighting...OMG! It also has negatively affected so many areas of my life
anyway no need to feel sorry for ourselves let's do something about this right?!
From other posts that I've read, Sarah usually recommends 1.5mm dermastamp and 1.5 dermaroller for scars (acne scarring). 1mm treats shallow scarring but it still may be a good starting place just until you know how your skin reacts to needling. She has also recommended the single needles to some but don't make the mistake I've made and use the diabetic lancets. I've made a couple of my scars wider (but shallower too..if that makes any sense) She also has advised others to get the .05mm dermaroller for overall texture improvement.
Since you are interested in keeping things simple, how about the 1mm dermastamp and if all goes well add the 1mm dermaroller and go from there. The dermastamp is actually an awesome tool if you have localized scars like me that are shallow to moderately deep. You may not need the 1.5 stamp/roller after all if your skin responds well to the 1mm. I have the 1mm dermastamp and recently ordered the 1.5mm dermaroller and 1.5 dermastamp because I feel some of my scars just need more aggressive treatment. I like Sarah's advice to treat the skin for 3 nites with the Vit C serum before needling. I've used the infoladan ointment after rolling/stamping for a few days and surprisingly, the ointment didn't break out my acne prone skin. Actually, it made my skin really soft and gave it a nice glow. Aside from the needling, I'm also making sure that my diet is good enough to help my skin heal. Needling is only half the battle. I must still help my body to help itself. Avoid a lot of sugar, fat, and salt. So a lot of fruits and veggies. Get my protein. Drink ALOT of water daily. Take my vitamins (especially C, E, and Zinc) and some exercise can only help the cause. Doing all of this, I feel like I'm actually forcing some positive results.
Sorry for writing you a book. As you can see I am pretty passionate about skin care. Best of luck with whatever regimen that you decide to use and keep researching when you have the time. There's always so much to learn
Hope I helped at least a little bit!
Take care!
