Safety Description


References Alexander J. Pallenberg, D., et al.: US., (1994);

AHK-Cu is a peptide complex that consists of a tripeptide called L-α-Amino-N-hydroxyethylglycine (AHK) and copper (Cu). This peptide complex has gained attention in the field of skincare and cosmetic formulations due to its potential benefits for skin health and rejuvenation.

AHK-Cu is believed to have antioxidant properties and the ability to promote collagen synthesis. Collagen is a structural protein that provides support and elasticity to the skin, and its production tends to decrease with age. By stimulating collagen synthesis, AHK-Cu may help improve skin firmness, reduce the appearance of fine lines and wrinkles, and enhance overall skin texture.

Furthermore, AHK-Cu is thought to possess wound-healing properties. It has been suggested that the peptide complex can accelerate tissue repair and regeneration, making it beneficial for individuals with skin damage, such as scars or sunburns.

In skincare products, AHK-Cu is often included in formulations such as serums, creams, and masks. It is typically used as an active ingredient that targets specific skin concerns, particularly those related to aging and skin damage. However, it’s important to note that individual results may vary, and the efficacy of AHK-Cu may depend on various factors, including formulation concentration, application frequency, and individual skin characteristics.

As with any skincare ingredient, it is advisable to consult with a dermatologist or skincare professional before incorporating AHK-Cu or products containing AHK-Cu into your skincare routine. They can provide personalized advice and guidance based on your specific needs and skin condition.
