Peptides
Peptides are the ‘messengers’ of skincare — tiny fragments that signal the skin to behave in helpful ways. Here's a grounded look at what they can and can't do.
What they are
Peptides are short chains of amino acids — the building blocks of proteins like collagen. In skincare, specific peptides act as signals, gently prompting the skin to support its own processes, from firmness to hydration.
There are many types, each with a different intended role, which is why ‘peptides’ is really a family rather than one ingredient.
What they're designed to do
Depending on the peptide, formulas are designed to support the look of firmness and smoothness, help maintain hydration, or support the skin barrier. They're gentle and generally well tolerated, making them a good long-term addition.
Honest expectation: peptides are supportive skincare, working with your skin over time — not a substitute for professional treatments where firmness is the main goal.
How to use them
Peptides layer well within a routine and pair nicely with hydrators like hyaluronic acid. They're a steady, tolerable active rather than a strong one, so they suit most people, morning or night.
Which peptide formula genuinely suits your skin is best chosen with guidance rather than marketing claims.

Common questions
What do peptides do in skincare?
They act as signals that gently prompt the skin to support its own processes — such as firmness, hydration or barrier health, depending on the peptide. They're supportive, everyday actives.
Do peptides really work?
They can support the look of firmness and hydration as part of a consistent routine, but they're gentle and gradual — not a replacement for in-clinic treatments where firmness is the primary goal.
Can I use peptides with retinol or vitamin C?
Generally yes — peptides are well tolerated and layer comfortably in most routines. If you're combining several actives, professional guidance helps you sequence them well.
