Pycnogenol (Pine Bark Extract)
Pinus Pinaster Bark Extract · Pinus Pinaster ExtractAntioxidant
A trade-name pine bark extract. It has more evidence taken by mouth than on skin.
What it does
It’s a trade name for an extract of maritime pine bark. Most of its studies are of pills, and its one skin study can’t show what pine bark does by itself. Not every pine bark extract on a label is Pycnogenol.
