@Tonya Huseby, great question and great timing getting started with Snap-8. Snap-8 is an octapeptide specifically designed for expression lines. It works by limiting the neurotransmitter release that causes repeated muscle contractions, which is what creates those deeper forehead and eye lines over time. Microneedling is one of the best delivery methods for it because you are driving it directly into the dermis where it needs to work. For the slip and glide issue you are right, reconstituted peptide solution alone is too thin for smooth microneedling coverage. Hyaluronic acid serum is the most common choice. A plain unfragranced HA serum gives you the glide you need, supports hydration in the skin during the treatment, and does not interfere with the Snap-8 mechanism. You are mixing the reconstituted Snap-8 directly into the HA serum before the session. Some people use a plain aloe vera gel as the base instead. Lightweight, soothing, good slip, and completely clean ingredient-wise so nothing interferes with the Snap-8 doing its job. What to stay away from is anything with active ingredients, acids, retinol, or fragrance mixed in. You want the carrier to be as neutral as possible so Snap-8 is the only active working during the session. For the mix ratio a common starting point is adding your reconstituted Snap-8 to a small amount of HA serum, enough to cover the treatment area comfortably. You do not need much, just enough for smooth pass coverage without dragging.
