VII. Parameter Correspondence and Function Description

Parameter 1 Function Description

Hypoallergenic formulations are the core competitive advantage of products for sensitive skin. By strictly controlling irritating ingredients and prohibiting known allergens, the risk of allergic reactions is reduced from the source. The pH value is controlled within the range of 5.0-6.0, close to the natural pH of healthy skin, preventing pH imbalances that could trigger barrier stress. A preservative-free system (combined with BFS aseptic filling) fundamentally eliminates preservative irritation, and the absence of fragrances and colorants further reduces potential allergens, maximizing safety for sensitive skin.

Parameter 2 Function Description

A comprehensive irritation testing system provides multi-layered safety assurance. Erythema testing assesses immediate irritation; cumulative irritation testing simulates long-term repeated use; eye irritation testing covers periorbital safety; and microbial challenge testing ensures the effectiveness of the preservative system. These four tests verify the product's safety for sensitive skin from different dimensions, providing a reliable safety endorsement for the brand.

Parameter 3 Function Description

The 100ml-200ml toner and lotion set is suitable for daily skincare, meeting the long-term stabilization needs of sensitive skin; the 15ml-30ml serum is suitable for precise repair, with a concentrated formula specifically addressing barrier damage; and the 25ml-30ml mask is suitable for intensive soothing care. Samples starting from 500 pieces support brands in quickly validating formulas and gathering market feedback, while mass production starting from 10,000 pieces reduces unit costs.
