PLLA (Poly-l-lactic Acid) and PCL (Polycaprolactone) are both biodegradable materials widely used in skin fillers, capable of stimulating the body's collagen production and thereby improving skin texture and elasticity. However, they have some distinct characteristics, and the potential advantages of PLLA over PCL may include:

1. **Long-Standing Clinical Usage**: PLLA has been used as a skin filler for quite some time, with its clinical efficacy and safety broadly researched and validated. This offers a wealth of experience for doctors, helping them to better predict and manage treatment outcomes.

2. **Stimulation of Collagen Production**: While both PLLA and PCL can stimulate collagen production, some studies suggest that PLLA might be more potent in this regard. This could make PLLA more effective in improving skin texture and elasticity.

3. **Durability of Treatment Results**: Although PCL degrades over a longer period, it does not necessarily translate into longer-lasting treatment effects. Some studies suggest that despite PLLA's shorter degradation time in the body, its treatment effects could last longer due to its potent stimulation of collagen production.

4. * * Safety * *: The degradation product of PLLA is LA, which is a substance inherent in the human body and can be absorbed and degraded by the human body, making it harmless to the human body. The degradation products of PCL cannot be absorbed by the human body.
