PCA (polycaprolactone) and PLA (polylactic acid) threads are similar to PDO threads used in cosmetic procedures, but offer variations:
All dissolve naturally: Like PDOs, PCA and PLA threads eventually break down and are absorbed by your body.
Lifting power: PCA threads, sometimes barbed, provide a stronger lift for moderate sagging. PLA threads focus more on collagen stimulation for a long-lasting effect (up to 2-3 years).
Talk to a professional: Each thread type has pros and cons. A consultation can determine which best suits your desired outcome.
