Chlorophyllin is a water-soluble, semi-synthetic derivative of chlorophyll (typically a copper complex) used in topical formulations for its antioxidant, anti-inflammatory, and deodorizing properties. It has been studied for acne, photoaging, and wound healing.
| Reported effect | How often | Notes |
|---|---|---|
| Temporary green-tinted staining of skin or fabric | Common | Due to the intense pigment; washes off easily and is cosmetic rather than harmful. |
| Mild skin irritation or transient stinging | Uncommon | More likely on sensitive or compromised skin. |
| Contact dermatitis or allergic reaction | Rare | Presents as redness, itching, or rash; discontinue use if it occurs. |
| Photosensitivity | Very rare | Chlorophyll derivatives have theoretical photosensitizing potential, though topical reactions are seldom reported. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
