【Laboratory-Grade】Dental Pulp Stem Cell Exosome Serum

Anti-Aging · Scar Repair · Sensitivity Relief · Bio-Remodeling

 DPSC-Derived Exosomes | Neurogenic Origin | Fibrosis-Modulating

1. Core Product Introduction

This product utilizes cutting-edge cellular biotechnology to extract highly active and purified exosomes from laboratory-cultured human dental pulp stem cells (DPSCs). Derived from the embryonic neural crest, DPSCs possess superior neurotrophic, angiogenic, and immunomodulatory properties compared to mesenchymal stem cells of mesodermal origin. Their secreted exosomes are naturally enriched with pro-regenerative proteins, anti-fibrotic microRNAs, and neurotrophic factors. Upon topical application, they precisely penetrate the skin barrier, target fibroblasts, melanocytes, and microvascular endothelial cells, regulate extracellular matrix remodeling, and balance inflammatory and fibrotic signaling—achieving multi-layered rejuvenation, scar prevention, and barrier fortification.

2. Mechanism of Action

Anti-Wrinkle & Lifting
Activates dermal fibroblasts; upregulates Type I & III collagen and tropoelastin synthesis; improves fine lines, nasolabial folds, and laxity.

Scar Remodeling & Fibrosis Inhibition
Selectively inhibits keloid fibroblast proliferation and ECM overproduction while promoting normal fibroblast activity; reduces postoperative adhesions, atrophic acne scars, and hypertrophic scars.

Soothing & Redness Reduction
Modulates NF-κB and NLRP3 inflammasome pathways; suppresses IL-6, TNF-α; alleviates facial erythema, rosacea, and post-procedure stinging.

Brightening & Pigmentation Control
Downregulates tyrosinase and TRP-1/2 expression; accelerates melanosome phagocytosis and shedding; improves post-inflammatory hyperpigmentation and uneven tone.

Barrier Regeneration & Microbiome Balance
Strengthens keratinocyte tight junctions; promotes ceramide synthesis; restores impaired acid mantle; enhances tolerance to chemical peels and retinoids.

4. Frequently Asked Questions (Q&A)

Q1: How is dental pulp stem cell exosome serum different from ordinary MSC exosome serums?
A: Dental pulp stem cells originate from the embryonic neural crest, not mesoderm. This grants them stronger neurotrophic, angiogenic, and anti-fibrotic capacities. DPSC exosomes are particularly effective in scar remodeling, nerve-ending sensitivity relief, and microvascular repair—advantages not found in umbilical or adipose-derived exosomes.

Q2: Can it really improve old acne scars and surgical scars?
A: Yes. DPSC exosomes uniquely inhibit pathological scar fibroblasts while promoting healthy dermal remodeling. Clinical observation indicates significant improvement in atrophic acne scars and early hypertrophic scars after 4–8 weeks of consistent use, especially when combined with microneedling.

Q3: Is this product suitable for post-laser or post-peel skin?
A: Absolutely. DPSC exosomes are rich in anti-inflammatory and pro-angiogenic factors that accelerate wound healing, reduce post-procedure erythema, and prevent post-inflammatory hyperpigmentation. They are ideal for medical aesthetic co-therapy.

Q4: How soon will I see results?
A: Most users report softer texture and reduced redness within 3–7 days. Visible improvement in fine lines, scar depth, and skin evenness typically appears within 2–4 weeks. Long-term use supports progressive dermal remodeling.

Q5: Why is refrigeration necessary?
A: Exosome lipid bilayer integrity and cargo bioactivity are temperature-sensitive. 2–8°C storage ensures optimal vesicle stability and functional potency. Cold chain shipping is strongly recommended. Do not expose to high temperatures or direct sunlight during storage or transit.

Q6: Can I use this serum during pregnancy or breastfeeding?
A: The product contains no hormones, retinoids, or chemical preservatives. However, as individual sensitivity varies, consultation with a healthcare professional is advised before use during pregnancy or lactation.
