The results of a recent trial of the use of Teoxane RHA Serum post-aesthetic treatment, in this case HA dermal fillers, microneedling and chemical peeling, have now been published in the Journal of Drugs in Dermatology and the results show a significant advantage.

Background: This split-face, controlled study investigated the ability of a topical crosslinked hyaluronic acid formulation (RHA serum)
to enhance clinical results from fillers, microneedling, or chemical peeling of aging skin. Previous comparative skin explant studies
demonstrated greater efficacy of RHA serum than topical non-crosslinked high or low molecular weight hyaluronic acid in decreasing
trans-epidermal water loss, increasing epidermal hydration, and improving corneocyte microstructure.
Methods: 24 female subjects aged 35 to 55 were enrolled. 8 received intradermal hyaluronic acid filler injection, 8 received microneedling,
and 8 received superficial mandelic acid chemical peeling. Subjects initiated twice-daily, standardized application of RHA serum to one
side of the face 2 days after the procedure. Topographical imaging, bioinstrumental, and blinded clinical evaluations were performed at
days 0, 14, and 28.
Results: Areas treated with RHA serum showed statistically significant improvements in skin surface topography and hydration compared
to untreated areas. Blinded investigator scoring showed greater improvement of RHA serum-treated skin in moisture, tone/complexion, radiance, texture, uniformity, and global appearance. Subjects’ questionnaire responses correlated with these findings. Subjects expressed
greater satisfaction with appearance of the treated hemiface. No adverse events were observed during the study.
Conclusions: When initiated post-procedurally, topical RHA serum was well-tolerated and enhanced biomechanical properties, quality,
and clinical appearance of the skin. Based on these data, RHA serum may be of value in improving patient outcomes and satisfaction
following minimally invasive aesthetic procedures. The availability of the same hyaluronic acid technology also as a cohesive,
tissue-integrating injectable filler enables synergistic, multi-level treatment plans to be devised.
