Efficacy of Platelet-Rich Plasma Versus Autologous Fat Transfer With Nanofat in the Treatment of Infraorbital Dark Circles: A Single-Blinded Randomized Comparative Clinical Trial

Efficacy and Safety of Autologous Nanofat Injection in the Treatment of Postburn Scars Using Optical Skin Imaging Analysis

BACKGROUND

Burn scars are considered one of the challenging issues that can affect the quality of life by causing aesthetic and functional problems. Injecting nanofat particles, which are considered a source of stem cells, into the dermis and/or subcutis of the burned area is considered a promising procedure for the treatment of scars and the correction of volume shortage and skin renewal.

OBJECTIVE

To assess the safety and effectiveness of using autologous nanofat injections to treat burn scars.

METHODS

Thirty patients with postburn scars participated in the trial. Each patient received one session of liposuction, which was then converted into nanofat and injected back into the scar tissue. Four months after the session, the evaluation was conducted both objectively using the Antera camera 3D imaging and subjectively using the Vancouver scar scale (VSS).

RESULTS

Because there were statistically significant improvements in the treated scars' height, color, vascularity, and pliability, the total VSS scores differed significantly before and after treatment. Furthermore, the Antera 3D imaging revealed a statistically significant variation in the treated scars' indentations, erythema, and pigmentation scores.

CONCLUSION

The study findings demonstrated that nanofat is a successful postburn scar treatment option that improves patients' quality of life.

Fractional CO 2 Laser Combined With Autologous Nanofat Injection Versus Fractional CO 2 Laser Combined With Platelet-Rich Plasma in the Treatment of Atrophic Acne Scars: A Split-Face Comparative Study With Optical Skin Imaging

BACKGROUND

Atrophic acne scarring is a common problem. If left untreated, its implications can impair the quality of life. Various treatments, with differing degrees of success, are used to alleviate atrophic scars.

OBJECTIVE

To assess the efficacy of nanofat versus platelet-rich plasma (PRP) as an adjuvant therapy to fractional CO 2 laser (FCL) for atrophic acne scars.

METHODS

This study included 35 patients with atrophic acne scars who received 3 sessions of FCL at 1-month intervals on both sides of the face, followed by intradermal PRP injection on the left side. A single session of nanofat was injected into the right side of the face 2 weeks before the laser sessions. The evaluation was conducted 3 months after the final treatment session.

RESULTS

After treatment, the right side of the face showed a significant reduction in Goodman scores and the indentation index of the Antera camera. The left side showed a significant difference in Goodman scores, yet the Antera camera showed a nonsignificant improvement. Nonetheless, the difference between the 2 sides was statistically insignificant.

CONCLUSION

Atrophic acne scars improved with both modalities. As a result, cotreatment with these techniques may synergistically affect atrophic acne scars in efficacy and safety.
