Exosomes are tiny nanovesicles, approximately 40-100 nm in diameter, actively secreted by cells. They contain bioactive molecules such as proteins, RNA, and lipids.
They act as "messengers" between cells, helping to transmit repair and growth instructions.
Skin care mechanism:
1. Anti-aging and Collagen Regeneration
① Thousands of studies have shown that exosomes can promote fibroblast proliferation and collagen production, enhance skin elasticity, and reduce wrinkles.
② It can also inhibit photoaging-related metalloproteinases (MMP-1/3), reduce UV damage, and improve texture and pigmentation.
2. Promote Repair and Wound Healing
① Exosomes can regulate immune responses (such as M1→M2 macrophage conversion), enhance healing, and reduce scarring.
② After cosmetic procedures such as microneedling and laser treatments, the combined use of exosomes can significantly reduce redness and swelling and accelerate recovery.
3. Improve Pigmentation
① It modulates tyrosinase activity through small RNAs, reducing melanin synthesis at its source, effectively fading spots and brightening skin.
4. Soothe Inflammation and Repair Sensitivity
① Its anti-inflammatory effects can alleviate skin problems such as acne scars, redness, and heat sensitivity, significantly improving skin condition.
