Hexapeptide-9 – CAS 1228371-11-6
Hexapeptide-9 is a six-amino-acid repair peptide with a molecular weight of approximately 750 Da, designed specifically for post-procedure skin recovery and intensive rejuvenation protocols. Identified by CAS number 1228371-11-6, this peptide targets the wound healing cascade by stimulating collagen III synthesis and accelerating keratinocyte migration across compromised tissue. Its profile makes it particularly valuable for the growing market of post-procedure skincare products used after chemical peels, microneedling, laser resurfacing, and fractional treatments.
Mechanism of Action
Skin repair follows a well-characterised sequence: inflammation, proliferation, and remodelling. Hexapeptide-9 acts primarily during the proliferation phase by stimulating fibroblast production of collagen type III, the initial collagen deposited during wound repair that later cross-links and matures into the stronger type I network. The peptide also promotes keratinocyte migration, accelerating re-epithelialisation of the treated zone. In scratch assay models using human dermal fibroblasts, Hexapeptide-9 at 50 ppm improved wound closure rates by 27% compared to untreated controls over a 24-hour observation period.
Clinical Relevance for Post-Procedure Care
The demand for post-procedure recovery products has grown in parallel with the expansion of minimally invasive aesthetic treatments. Patients undergoing microneedling, fractional CO2 laser, or medium-depth chemical peels experience controlled micro-injuries that benefit from accelerated repair. Hexapeptide-9 addresses this need directly by shortening the vulnerable recovery window when the barrier is compromised. Faster collagen III deposition also reduces the risk of post-inflammatory hyperpigmentation by restoring barrier integrity before UV exposure can trigger melanocyte overactivation.
Formulation Guidelines
Incorporate Hexapeptide-9 at 25-100 ppm in the aqueous phase. The peptide is water-soluble and stable across pH 5.0-7.0. It integrates well into post-procedure balms, recovery serums, soothing gels, and occlusive repair creams. Pair with centella asiatica extract, panthenol, allantoin, or beta-glucan for synergistic barrier recovery. Avoid combining with strong AHAs or retinoids in the same product, as these may counteract the repair signal by maintaining exfoliation pressure on healing tissue. Process below 40 degrees C and maintain aseptic conditions given the target application on compromised skin.
Applications
- Post-microneedling recovery serums and balms for professional clinics
- Post-laser soothing gels for fractional CO2 and IPL aftercare
- Post-peel barrier repair creams for chemical exfoliation recovery
- Intensive night repair treatments for chronically stressed or sensitised skin
- Wound-care-adjacent cosmetic products for minor cuts and abrasions

Frequently Asked Questions
When should Hexapeptide-9 be applied after a procedure?
Hexapeptide-9 products are typically applied starting 2-4 hours post-procedure, once initial bleeding has stopped. The peptide accelerates the proliferation phase, so early application maximises collagen III deposition during the critical first 48 hours.
How does Hexapeptide-9 differ from collagen-boosting peptides?
While most collagen peptides stimulate type I collagen for long-term firmness, Hexapeptide-9 specifically upregulates collagen III, the early-phase repair collagen. This makes it specialised for wound healing and post-procedure recovery rather than general anti-aging.
What concentration of Hexapeptide-9 showed efficacy?
In scratch assay studies, 50 ppm improved wound closure by 27% over 24 hours. The recommended formulation range is 25-100 ppm depending on the intensity of the target application.
