What it is
A synthetic dipeptide-like compound (a small chain of amino acids) designed to calm skin inflammation and reduce visible redness.
How it works
It inhibits the release of pro-inflammatory signals (like prostaglandins) in skin cells, which dampens the redness and irritation response. It also helps strengthen the skin barrier over time by supporting normal cell function.
Pros
Gentle calming action
Helps reduce redness and stinging without causing further irritation, making it ideal for sensitive skin routines.
Compatible with other actives
Can be layered with exfoliants or retinoids to buffer irritation, allowing you to keep using stronger ingredients.
Cons and cautions
Limited research
Most evidence comes from lab or small-scale studies; large human trials are lacking, so its real-world effectiveness is less certain.
Not a standalone solution
For significant redness or rosacea, it works best as part of a broader routine rather than as a sole treatment.
Best for
- People with sensitive or easily irritated skin
