Scarless works as follows:

-Scarless aids in the reduction of inflammation, which is a major factor in scar formation. Inflammation can turn the scar red, elevated, and itchy. Scarless reduces inflammation by forming a barrier over the scar that keeps irritants and allergens out.
-Scarless promotes collagen formation, which helps to fill up the scar and make it less visible. Collagen is a protein that gives skin flexibility and strength. Scarless promotes collagen formation by establishing a moist environment that encourages cell development.

-Scarless aids in the protection of the skin from irritants and allergens.
