What is Injectable Grade PCL

I think everyone is very familiar with facial filling and body filling technology in the medical beauty industry.

With the development of biodegradable materials, polycaprolactone is a medical-grade polymer that can be completely absorbed by the human body. It is both biocompatible and Biodegradability has also been found by scientists to be used for body injections. PCL polymer can achieve a natural firming effect on the skin by stimulating its own collagen regeneration. If we have sunken areas on the face, including nasolabial folds, they can be improved in time, so polycaprolactone biodegradable have also joined the medical beauty industry.

Now I will introduce the most popular product “Girl’s Needle” to experience the girlish face with one shot and help you find your younger self!

The core ingredient of Girly Needle is Uli-Eco’s polycaprolactone (PCL). Let’s take a deeper look at polycaprolactone products:

First of all, polycaprolactone (PCL) has good biocompatibility and is stable and safe after entering the human body. At the same time, PCL ingredients also have powerful repair and regeneration functions, allowing cells to proliferate, continuously and rapidly secrete collagen, stimulate the reconstruction of deep elastic fibers, strengthen the skin from the inside out, enhance resistance, maintain the health of the skin, and achieve skin texture reversal.

Second, polycaprolactone (PCL) degrades into non-toxic, bioabsorbable products in the human body, which are metabolized into CO 2 and H 2 O and excreted through normal pathways.

Third, the safety of polycaprolactone (PCL) has been approved by authoritative agencies in many countries and regions such as China’s NMPA and the US FDA for use in human implants.


Of course, there are many types of products on the market, because there are different models of girl needles. How do users distinguish between these models? In fact, the main difference between PCL injection needles is the length of maintenance time. This is because the chain length of polycaprolactone (PCL) is controllable, and its maintenance time in the human body depends on the chain length and molecular weight of the material; if you want to extend the maintenance time Time, the maintenance time of the product can be controlled by controlling the length of the polycaprolactone (PCL) ester bond chain


Summary of the efficacy of polycaprolactone suppliers Unilong:

  1. Lifting and firming, promoting collagen proliferation, wrinkle removal and beautifying skin;
  2. Restore skin elasticity, replenish hyaluronic acid lost by the human body due to aging, relieve wrinkles, and resist aging;
  3. The ingredients of the repair factor promote the regeneration of tissue cells, improve the dull complexion, and make the skin shiny and bright;
  4. Maintain cell moisture, make the skin absorb and store more moisture, and moisturize the skin for a long time;
  5. Prevent skin aging and pigmentation, reduce the formation of melanin, and achieve the effect of whitening and lightening spots

The size of PCL microspheres provided by Uli-ECO New Materials is 25-50 µm. Because phagocytosis does depend on the size of the microspheres: the smaller the particles, the faster the phagocytosis and the higher the degree of inflammation. PCL fillers are made from PCL microspheres 25-50 µm in size, protecting them from phagocytosis! If you want to know more about PCL, please feel free to ask Unilong!
