Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic dipeptide-like compound that combines two cinnamic acid derivatives with a propane linker. It is designed to deliver soothing and barrier-supporting benefits without the variability of natural extracts.
How it works
It interacts with skin cells to help reduce the production of pro-inflammatory signals, which can calm visible redness and irritation. At the same time, it supports the skin's lipid barrier, helping it retain moisture and resist environmental stressors.
Pros
Calms redness gently
Helps reduce the appearance of redness and irritation without harsh side effects, making it ideal for sensitive skin.
Supports skin barrier
Encourages a stronger moisture barrier, which helps skin stay hydrated and resilient against daily stressors.
Cons and cautions
Limited research
While promising, the ingredient has fewer peer-reviewed studies compared to well-established soothing agents like niacinamide.
Synthetic origin
Some consumers prefer naturally derived ingredients; this is a lab-made compound, which may be a consideration for 'clean beauty' enthusiasts.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, non-irritating way to support skin barrier health
Use caution if
- Individuals with known allergies to synthetic peptides or cinnamic acid derivatives (rare)
