Plant stem cells are extracts derived from cultured plant cells (e.g., apple, edelweiss, grape) marketed for antioxidant and skin-conditioning effects. Despite the name, they do not contain living, functional stem cells in finished products but rather plant cell extracts and metabolites.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation or redness | Uncommon | May occur due to plant-derived compounds or accompanying preservatives in formulation. |
| Allergic contact dermatitis | Rare | Possible sensitization to specific botanical components in susceptible individuals. |
| Phytophotodermatitis | Very rare | Reported only with certain plant species containing photosensitizing compounds. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
