**7. Conclusion**

While patient acceptance of injectables has been high, many educated consumers are now seeking regenerative solutions for their esthetic needs. Combination treatment of the skin and subcutaneous stromal scaffold is attractive to both patients and physicians. The use of exosomes to signal cells in the treatment region is a rapidly growing trend. When combined with a light resurfacing protocol, exosomes accelerate the healing process while delivering mRNA, cytokines, chemokines, and growth factors. Restoration of the support system of the skin, the subcutaneous stroma, can be enhanced with PDO resorbable threads that are biostimulatory. Mono threads will generate directional collagen ingrowth in the superficial hypodermis. Barbed suspension threads can support sagging regions. Cylinder configured threads can be used alone or in combination with filler or fat. These injectable implants can replace small surgically introduced facial implants in many cases. Microlifting using suspension threads combined with regenerative techniques is a popular alternative to traditional injectable techniques.
