Pyridoxal 5-phosphate is the biologically active coenzyme form of vitamin B6, used in skincare for its role in cellular metabolism, sebum regulation, and antioxidant support. It is more bioavailable than pyridoxine and may help with conditions linked to B6 metabolism in the skin.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation or redness | Uncommon | Typically transient and associated with higher concentrations or sensitive skin. |
| Contact dermatitis | Rare | Allergic or irritant reactions have been occasionally reported with topical B6 derivatives. |
| Photosensitivity | Rare | Limited reports; vitamin B6 compounds can theoretically increase sensitivity to light in some individuals. |
| Stinging or burning sensation | Uncommon | More likely on compromised or freshly exfoliated skin. |
