Pinus Pinaster (Pine) Bark Extract, often standardized for procyanidins (e.g., pycnogenol), is a polyphenol-rich botanical used in skincare for its antioxidant and free-radical-scavenging properties. It is also studied for supporting microcirculation and reducing signs of UV-induced and oxidative skin damage.

| Contact allergy/allergic dermatitis | Rare | Possible sensitization in individuals allergic to pine or plant polyphenols. |
| Gastrointestinal upset | Uncommon | Reported mainly with oral supplementation rather than topical use; not typically relevant to skincare. |
