Copper Peptide for Eyebrows and Eyelashes

Regarding the use of Copper Peptide (GHK-Cu) at 3% in an Aloe Vera gel base for lengthening eyebrows and eyelashes:

• Mechanism: Copper Peptide (GHK-Cu) is known for its ability to nourish hair roots and stimulate new hair growth, rather than significantly lengthening existing hair strands. This aligns with the information provided in the previous reply.
• Concentration: A 3% concentration is within the recommended usage range for the liquid forms of Copper Peptide (GHK-Cu) solutions.
• Application on Eyebrows and Eyelashes: While the product descriptions mention stimulating hair growth generally, they do not specifically address application on eyebrows or eyelashes. When applying any product near the eyes, it is crucial to exercise caution.
• Eye Irritation: The product descriptions do not provide specific information about potential eye irritation. However, the eye area is sensitive, and applying cosmetic formulations near the eyes always carries a risk of irritation. It is advisable to perform a patch test first and avoid direct contact with the eyes.

In summary, Copper Peptide may help stimulate new growth in thinning areas of eyebrows and eyelashes, but it is less likely to make existing hairs significantly longer. Use with caution around the eyes.
