Usage Percentage and Effectiveness of Wrinkle Lax

Based on the staff's reply regarding Wrinkle Lax:

• The manufacturer tested usage up to 0.5%, and the staff's recommendation of 0.5% is based on this data.
• The staff confirms that using Wrinkle Lax at 1.0% is safe and not harmful to the skin.
• However, the staff notes that based on the manufacturer's findings, the difference in effectiveness between 0.5% and 1.0% might not be significant. This is why the manufacturer recommends a maximum of 0.5%.
• Therefore, while 1% is safe, the staff does not have experimental data to confirm a significantly better performance compared to 0.5%. The maximum recommendation from the manufacturer is 0.5%.
