GHK-Cu is a tripeptide copper complex naturally present in the human body. As we age, the amount of this substance in the skin gradually decreases. The 100mg powder provides ample and flexible options for daily skincare formulation, allowing for customization to suit different skin types and needs. The ingredient is a fine, light blue powder. Its water-soluble properties allow it to gently dissolve in pure water and basic moisturizing bases. Its small molecular structure easily penetrates the stratum corneum to reach the deeper layers of the skin and exert its effects. Compared to some irritating skincare active ingredients, it is gentle on sensitive skin and less likely to cause intolerance with long-term use. It acts as a signaling medium for the skin, awakening the vitality of dermal fibroblasts and promoting the natural production of collagen, elastin, and hyaluronic acid-related substances. This gradually fills in fine lines caused by collagen loss, improving skin laxity and dryness, while regulating the skin's matrix metabolism balance, resulting in smoother and more refined skin texture. For skin prone to redness during seasonal changes, minor barrier damage, or fragile skin after cosmetic procedures, this product possesses soothing and repairing properties. It reduces discomfort on the skin's surface, helps repair damaged keratinocytes, reduces inflammation caused by external stimuli, and neutralizes free radicals generated by the environment, reducing dullness and roughness caused by oxidation. The 100mg dose can be divided for multiple applications. A small amount of powder diluted for each application is sufficient for the entire face. Remaining powder should be stored in a cool, dry place in a sealed container to maintain its stable activity. It is recommended for evening skincare after preparation. After cleansing and gently patting dry, apply the diluted solution and wait for complete absorption before applying a moisturizing cream. Using sunscreen during the day will further enhance the skin's improved condition. In addition to facial care, the diluted solution can also be gently applied to the scalp to improve the scalp microenvironment and alleviate hair breakage, dryness, and itching. With consistent and regular use, the skin's radiance and suppleness will gradually change. There's no need to pursue rapid changes. Relying on the ingredients' inherent biological properties, it gently achieves a skincare experience that balances repair and rejuvenation, making it suitable for various daily skincare scenarios where you want to stabilize, fight aging, and repair your skin barrier.
