A topical serum containing peptides targeting iron clearance, collagen stimulation, and antimicrobial activity reduced post-injection bruise intensity by 73% at day 2-3 compared to moisturizer alone.
73%less bruise color intensity at day 2-3 with peptide serum vs. moisturizer
What the researchers found
At day 2-3 post-injection, participants using the peptide-containing serum had 73% less bruise color intensity and 81% showed less bruising compared to the bland moisturizer control.
Why it matters
Bruising after cosmetic injections is a top patient concern that limits procedure frequency and satisfaction. A validated topical product that accelerates healing could significantly improve the injectable procedure experience.
The numbers in context
Reduced bruising, swelling, and pain versus controls.
How the study worked
Human clinical study comparing a peptide-containing topical product (INhance Post-Injection Serum with TriHex Technology) versus bland moisturizer for post-injectable procedure recovery. Bruise color intensity measured at multiple time points.
Who was studied
Patients receiving cosmetic injectable procedures
What this study cannot tell us
Industry-sponsored study (Alastin Skincare). Comparison was against bland moisturizer rather than an active comparator. Specific peptide concentrations and formulation details not fully disclosed. Relatively small study window.
How to read the evidence
Human clinical study with measurable outcomes and statistical significance, though industry-sponsored with a bland moisturizer comparator.
When this study was published
Published in 2020. The product (TriHex Technology) has since gained wider clinical adoption.
The bigger picture
As demand for injectable cosmetic procedures continues to grow, reducing downtime and visible side effects becomes increasingly important. Peptide-based topical adjuncts represent a science-backed approach to faster recovery that could become standard post-procedure care.
Questions still open
- Which specific peptides in the formulation are most responsible for the anti-bruising effect?
- How does this product compare to arnica or other common post-procedure remedies?
- Would the collagen and elastin stimulation provide measurable long-term skin benefits beyond bruise resolution?
Common questions
How do peptides help with bruise healing?
Can this serum be used after any type of injection?
