What Is Quercus Petraea Bark/Wood/Leaf Extract?
Quercus Petraea Bark/Wood/Leaf Extract comes from the bark, inner wood and leaves of the sessile oak tree, a sturdy oak native to much of Europe. These parts of the tree hold a mix of tannins, flavonoids and other plant antioxidants that can calm and protect skin.
Oak bark has been valued for centuries in folk care and in the tanning of leather thanks to its high tannin content. As skin care moved toward more plant based formulas, makers began studying oak extracts for their soothing and protective traits, which led to its inclusion in modern cosmetic lines.
To make the extract, harvesters gather healthy bark, wood and leaves, dry them then grind them into a fine material. This material is soaked in a solvent such as water, glycerin or a mild alcohol to pull out the useful compounds. After steeping, the liquid is filtered and concentrated before being added to cosmetic bases.
You will most often spot Quercus Petraea Bark/Wood/Leaf Extract in toners, sheet masks, calming creams, anti aging serums and aftershave lotions where an extra soothing touch is wanted.
Quercus Petraea Bark/Wood/Leaf Extract’s Cosmetic Benefits/Uses
This ingredient is prized for one main job in skin care.

Who Can Use Quercus Petraea Bark/Wood/Leaf Extract
Most skin types can enjoy this oak derived extract. Oily, combination or easily flushed skin often benefits the most because the gentle astringent tannins can calm look of redness and help the surface feel smoother. Normal skin usually tolerates it well too.

If a fully vegan routine is important, check with the brand about any animal based solvents or secondary ingredients in the finished formula.

Comedogenic Rating
Rating: 1/5. Quercus Petraea Bark/Wood/Leaf Extract is water-soluble, contains very little oil and has mild astringent tannins that can actually help keep pores feeling clean, so the chance of it clogging pores is quite low. Because of that, it is generally suitable for people who are prone to acne or frequent breakouts. Only formulas that pair the extract with heavier oils or waxes could raise the clogging risk, so always consider the full ingredient list.
