Melanin and erythema indexes before and after transplantation. (a) The erythema index of the scar area was similar to the control area before FT. It experienced a decline and reached below the erythema level of the control area after the second FT. (b) Melanin index of the scar area was higher than the control area before FT. It declined to levels similar to melanin index in the control area. The patient's right cheek quality was assumed as the control at each time point. FT: fibroblast transplantation.

As Figure 1 demonstrates, after transplantation, the erythema index experienced a slight decline and reached below the erythema level of the control area (Figure 1(a)). Melanin index of the scar area reached levels similar to the control area (Figure 1(b)).

The R2 (gross elasticity), R5 (net elasticity), and R7 (skin firmness) parameters doubled, indicating a skin elasticity improvement in the scar area (Figure 2).
