An essential oil distilled from Cinnamomum cassia leaves with an intense cinnamon aroma. Used mainly as a spicy fragrance; high cinnamaldehyde content means very low inclusion levels and limited evidence for regular topical benefits.
A bold cinnamon-scented oil that can be sensitizing for some skin.

Skin Benefits
Delivers a bold cinnamon character; skincare benefits beyond scent are not well supported and it can be sensitizing for some users.
Uses In Skincare & Cosmetics
Primarily included in perfumes, body sprays, and fragranced wash-offs like shower gels at very low percentages due to potency.
Comedogenic Rating
This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.
Safety
Potent and volatile, with a higher likelihood of stinging, redness, or allergic reactions; keep levels low and avoid broken or very sensitive skin. EU rules require labeling of certain fragrance allergens above thresholds.
Is Cinnamomum Cassia Leaf Oil a Good Ingredient?
Chiefly a perfume material with minimal proven skincare value, and its cinnamaldehyde-rich profile heightens irritation and sensitization risk, especially in leave-ons. That combination of weak skin benefit and real irritation risk is why it only earns a Poor rating.
