Ingredients and peptides

The formula combines the copper peptide Copper Tripeptide-1 with Acetyl Tetrapeptide-3. Panthenol, also known as provitamin B5, cares for the delicate lash line, while carnosine and red clover extract complete the recipe.

The water-based texture with glycerin and hydrolysed hyaluronic acid does not make lashes sticky and works well with make-up.

How to use

Once a day, ideally in the evening, apply with the applicator along the upper lash line on cleansed, dry skin – like a fine eyeliner.

Let it dry briefly before applying other products. Do not apply directly into the eye; if it gets into the eye, rinse thoroughly with water.

Who is it for?

The serum is designed for daily care of lashes that feel weak or brittle – for fuller-looking, well-groomed lashes.

Together with the Scalp Serum, it is available in the Copper Peptide Hair & Lash set.

Copper peptides in skin care

Copper Tripeptide-1 is the INCI name of the copper peptide GHK-Cu, a complex of the tripeptide glycine-histidine-lysine and copper. In cosmetics it is used as a conditioning ingredient in serums, creams and scalp products.

Cosmetic peptides are often divided into three groups: signal peptides such as Palmitoyl Tripeptide-1, carrier peptides such as Copper Tripeptide-1, which binds copper, and peptides such as Acetyl Hexapeptide-8, known for their smoothing effect on the look of the skin. Many modern formulas combine several of these groups.

All cosmetic ingredients permitted in the EU, and their functions, can be looked up in the official CosIng database of the European Commission. More products are in our peptide skin care category.

Storage and shelf life

Keep the product tightly closed in a cool, dry place and protect it from direct sunlight. A bathroom windowsill or a spot next to the radiator is not a good place for peptide care.

How long a product can be used after opening is shown by the open-jar symbol (PAO) on the packaging, for example "12M" for twelve months. If the smell, colour or texture changes, please stop using the product.
