Cinnamic Acid
Cinnamic acid is an aromatic organic acid found in cinnamon and also made synthetically. It's used in perfumes and cosmetics to give warm, balsamic notes and as a precursor for fragrance esters, though higher levels can raise sensitization risk.

Our take
Is Cinnamic Acid a Good Ingredient?
It provides warm, balsamic scent nuances but offers no direct skin care benefit and has a sensitization/irritation risk at higher or prolonged exposure. Best used at low levels; patch testing is prudent for sensitive users. Limited proof of benefit weighed against the risk keeps it at Fair.
What it does
Skin Benefits
Provides a warm, sweet-spice aroma that makes products smell richer and more inviting. May provoke sensitivity in some users, so a patch test is wise.
Where you'll find it
Uses in Skincare & Cosmetics
Appears in perfumes, moisturizers, and shampoos to round out scent profiles or support other aroma ingredients.
Before you use it
Safety
Can irritate sensitive or compromised skin and may trigger sensitization in some individuals; avoid use on broken skin and discontinue if redness occurs. Typically used at low concentrations, often guided by industry standards (e.g., IFRA).
