Does this scar gel fully absorb or create a barrier? Will it impact the absorption of hyaluronic acid/vitamin c serum, moisturizer, etc.?

Initially our medical-grade silicone will make a barrier, but then does get absorbed or rubbed away with time.

Pure 100% Medical-grade Silicone scar gel is the #1 plastic surgeon recommended ingredient to combat scarring. Per studies, it is best without additional ingredients that may destabilize the healing environment created by the silicone barrier between the skin and outside environment. Other ingredients like growth factors, SPF, etc - can cause the barrier to be less than adequate.

While you can use other products on the scar as directed by your physician, our team recommends at least using this product separately and as directed multiple times a day for best results. This means applying our Scar Gel directly to dry skin and allowing it to dry before using other products.
