— What Peptides Actually Do (In Simple Terms)

*Peptides are short chains of amino acids — tiny messengers that tell your cells what to do.

Different peptides send different signals:

• Some tell your skin to make more collagen

• Some support cellular repair

• Some help regulate appetite

• Some support mitochondrial energy

• Some help brighten or firm the skin

Think of them as targeted instructions for your body.
