How does Spectragel cream work? Spectra Gel works as a moisturizer for the cutaneous layer of the affected skin and limits the spread of collagen in it, which gives the scar softness and suppleness and allows the skin to breathe. It works to protect the affected skin tissues from bacterial infection by eliminating the collagen gathered around the torn tissues. It works to stimulate the fibrous cells spread in the affected skin, which limits the aggregation of collagen in the affected area, which contributes to restoring the fibrous swelling of the skin to normal. Spectra Gel cream helps, through silicone, to increase the elasticity of the astringent tissues in the skin, which contributes to reducing scars or removing their effects, depending on the condition the scar reaches.
