Carbomer is a synthetic high-molecular-weight polymer of acrylic acid used to thicken, stabilize, and control the viscosity of gels, creams, and lotions. It functions as a formulation aid rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient skin irritation | Rare | Occasional stinging or redness, more likely on compromised or sensitive skin. |
| Allergic contact dermatitis | Very rare | Sensitization is considered very uncommon; carbomer has low allergenic potential. |
| Eye irritation | Uncommon | Can cause stinging or irritation if products contact the eyes. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
