Core Efficacy
Promote the synthesis of collagen and elastin
Acetyl tetrapeptide-2 upregulates gene expression associated with collagen synthesis and adhesion plaque protein (FAK), significantly enhances type I collagen production, and stimulates the formation of fibronectin, thereby improving skin firmness and reconstructing epidermal structure.
Enhance the activity of FBLN-5 and LOXL-1
It promotes the synthesis and activity of Fibulin-5 (the elastic fiber anchoring protein) and Lysyl oxidase-like protein-1 (LOXL-1), both of which are essential for the proper formation of elastic fibers, thereby effectively combating skin laxity and sagging.
Enhance skin elasticity and firmness
Through multidimensional synergistic effects—promoting the synthesis of type I and III collagen, enhancing the skin's elastic fiber network, improving facial contour, and reducing wrinkles and fine lines.
Strengthen the skin barrier
Supports the skin's natural barrier function, helps retain moisture, enhances skin softness and texture, and improves radiance.
Highly safe, mild, and non-irritating
The acne-inducing rating is 0 (lowest). Its water-soluble formula does not clog pores and is suitable for all skin types, including sensitive skin.

Formulation Precautions
Administration timing: Add during the final stage of cosmetic production (low-temperature phase), with temperature not exceeding 40°C, to avoid peptide chain degradation caused by high temperatures.
pH range: The recommended formulation pH should be controlled between 5.0 and 7.0.
Contraindications: Avoid concurrent use with strong acids (high-concentration fruit acids/salicylic acid), strong oxidizing agents, or heavy metal ions.
Synergistic ingredient recommendation: Can be combined with hyaluronic acid, collagen peptides, hexapeptide (acetylated hexapeptide-3), nicotinamide, etc., to achieve synergistic effects.
Dissolution method: First, completely dissolve the lyophilized powder with a small amount of pure water or buffer solution, then add it to the formulation and stir thoroughly.
