Developing a Topical Adjunct to Injectable Procedures.

Injectable procedures have come to play an enormous part in everyday aesthetic medical practice. Whether its use is directed at volumizing with fillers, decreasing volume using enzymes, skin-tightening using multi-needle approaches, or neuromuscular blockade, the injectable route is the means of delivery in all these cases, making injectable procedures the most common aesthetic procedure performed. As with all procedures, expected and unexpected consequences may follow including bruising, swelling, discomfort, and the possibility of infection. This paper outlines the scientific process and validation of a product designed as an adjunct to injection therapy and the scientific deep dive needed to encompass both symptomatic and adjunctive purposes. On the symptomatic side, bruising, swelling, and pain were considered, while volumetric enhancement, regeneration, and anti-microbial/biofilm effects were desired outcomes from the adjunctive perspective. Utilizing peptides and active agents aimed at reducing excess residual iron and stimulating macrophage absorption of red blood cells, we were able to achieve efficient resolution of bruising. In addition, peptides were included to stimulate collagen, elastin, and hyaluronic acid in synergy with the injectable. Anti-inflammatory, antimicrobial, and antibiofilm agents were added to aid in the safety profile of the injectable. In vivo testing of bruising resolution demonstrated that at day 2/3, participants using the study product (INhance Post-Injection Serum with TriHex Technology®, Alastin Skincare, Inc. Carlsbad, CA) had 73% less bruise color intensity and statistically significant improvement over the bland moisturizer. Overall, 81% of subjects applying the study topical product had less bruising at day 2/3 compared to the bland moisturizer. J Drugs Dermatol. 2020;19(4):398-404. doi:10.36849/JDD.2020.5016.
