Atrophic scars, a permanent complication of severe acne, have negative effect on psychology in adolescent. The treatment of atrophic scar is depended on types of scar and it is difficult to improve by a single treatment. Mesenchymal stem cell is a scientific approval for surgery scar treatment and wound healing. We present a case report of female presented with atrophic acne scar distributed on both cheeks. The case aims to prove that the combination of MSCs and aqueous human placenta extract (RGF ) contained bioactive therapeutic molecules obviously promoted the improvement of skin scar to reach the optimal outcomes. We first found that MSCs-contained human placenta extract solution combination subcision improves the atrophic acne scar and skin complexity by enhancement of skin cell regeneration.

Hyperpigmentation is a common skin problem in a woman. Prolonging topical use of skin whitening may cause hyperpigmentation such as ochronosis whose condition is a challenge for treatment. An aqueous human placenta extract (RGF®) contains bioactive therapeutic molecules. There is evidence of human placenta extract showing that melanin synthesis is inhibited by placenta extract in melanocytes. We first reported the case of the hyperpigmentation improvement following face skin mesotherapy human placenta extract treatment.
