Kojic acid is a fungal-derived organic acid used in topical formulations to reduce hyperpigmentation by inhibiting tyrosinase, the key enzyme in melanin synthesis. The 'globules' format encapsulates the acid to improve stability and controlled release.
| Reported effect | How often | Notes |
|---|---|---|
Contact dermatitis / skin irritation | Common | Redness, itching, and stinging, especially at higher concentrations or on sensitive skin. |
Allergic contact sensitization | Uncommon | Kojic acid is a recognized sensitizer; repeated exposure can lead to allergy. |
Erythema and dryness | Common | Mild transient redness and flaking during initial use. |
Increased photosensitivity | Uncommon | Skin may become more reactive to sun; daily sunscreen is advised. |
Paradoxical hyperpigmentation | Rare | Worsening of pigmentation reported with overuse or improper application. |
Severe systemic allergic reaction | Very rare | Rarely reported; topical use generally limited to localized effects. |
