Skin Irritation Potential and Efficacy of Cosmetic Ingredients

Based on the staff's response:

Regarding the potential for skin irritation from the listed ingredients:

• Ingredients 1, 4, 5, 6, and 7 (SalicSoft, 4MSK, Pumpkin Renew, Kojic Acid Dipalmitate, Lemon Peel Bioferment) can potentially cause skin irritation if used at concentrations higher than recommended by the manufacturer or regulatory bodies.
• Using these ingredients within the recommended usage rates significantly reduces the risk of irritation. However, individual skin sensitivity varies, and it's not possible to guarantee that no irritation will occur for every user.

Regarding Calendula Extract and ingredients sold for marketing only:

• The research data shown for Calendula Extract on the website is based on real laboratory testing (in-vitro). It is not clinical testing (testing on actual users).
• The current Calendula Extract sold is confirmed to contain at least 0.5% Lutein as analyzed. However, due to individual skin differences, it cannot be guaranteed that the results for every user will be equivalent to the lab test results.
• Currently, no active ingredients sold by the company are intended solely for marketing purposes without efficacy results. All active ingredients have at least in-vitro research data.
• Other types of ingredients (non-active) may not have efficacy research.
