Skin injection fillers need thorough evaluation for market entry, focusing on intradermal reactions to ensure safety and compatibility.
The study introduces a detailed evaluation method, integrating various indicators like dermoscopy, moisture content, and ultrasound to assess the effects of sodium hyaluronate gel.
Findings reveal that while the gel showed minimal irritation and acceptable safety levels, existing assessment standards might not adequately measure its long-term effects, suggesting the need for improved evaluation methods.
