DESCRIPTION AND COMPOSITION
Etrebelle consists of two components: PLA (Poly D, L-lactic) and hyaluronic acid.
PLA (Poly D, L-lactic) is an FDA-approved polymer material with excellent biocompatibility and biodegradability,
which is non-toxic and harmless, and eventually metabolizes carbon dioxide and water to be excluded from the body.
Hyaluronic acid is a natural polymer polysaccharide widely distributed in all parts of the human body,
and it is also a very safe ingredient.
