Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Skin Graft Burn Patients Experimental Site; Both placebo and active cosmetic scar spray will be applied to different parts of the same scar on each participant. The active and the placebo spray will both be applied to the designated area of each scar twice per day. The amount sprayed will cover the designated area of the scar and then be massaged into to scar and surrounding skin with each application. This will be done twice daily for the nine-month duration of the study.	Other: Synochi Scar Spray Cosmetic; Application of the cosmetic on each skin graft in a blinded fashion in different sections for a 9 month duration.
PLACEBO_COMPARATOR: Skin Graft Burn Patients Placebo Site; Both placebo and active cosmetic scar spray will be applied to different parts of the same scar on each participant. The active and the placebo spray will both be applied to the designated area of each scar twice per day. The amount sprayed will cover the designated area of the scar and then be massaged into to scar and surrounding skin with each application. This will be done twice daily for the nine-month duration of the study.	Other: Synochi Scar Spray Placebo; Application of the placebo on each skin graft in a blinded fashion in different sections for a 9 month duration.
