What Is The Thread Of Buried Needle And Thread Carving? What's The Difference?

Line carving line: there are PPDO, PDO and protein line, we commonly use PPDO line. There are only two types of theoretical upper line: one is toothed, and the other is smooth. Smooth lines without teeth are divided into spiral, multi-root, long and short, thick and thin, and so on. The reason why so many lines are designed is that each line acts on different parts and can achieve different effects.

These lines are fundamentally different, protein lines are mostly purified from animal protein, it has allergens, it is artificial purified things, not pure chemicals. PDO and PPDO lines, on the other hand, are purely chemical, not purified from animals, and are more complete. PPDO is further purified on the basis of PDO.
