Ingredients and actives

Peptides

Also written as peptide serum, signal peptides, copper peptides.

Short amino acid chains used at low percentages in serums and eye products. Usually water-thin and usually expensive per gram.

What it needs from a bottle

Cost per millilitre changes the format. When the formula is expensive the customer notices waste, so an airless pump earns its price by emptying almost completely. Peptide eye serums are the strongest case for a small airless bottle in a whole range.

Formats that suit it

• 15ml and 30ml airless pumps
