Before we jump into the different types of peptides, let’s first look at how cells interact with eachother so we can better understand how peptides actually effect them.
The cells in our bodies are constantly communicating through chemical and mechanical signals. They have their own language but instead of words they communicate or “signal” using compounds, such as hormones or neurotransmitters.
When applied topically, peptides can be used to communicate specific actions, triggering a response in the cell.
There are five different types of peptides used as skin-care actives: signaling peptides, carrier peptides, enzyme-inhibiting peptides, neurotransmitter-inhibiting peptides and antimicrobial peptides. Let’s look at what each one does.
