What Is Quercus Acutissima Extract?
Quercus Acutissima Extract comes from the sawtooth oak, a hardy tree native to East Asia and prized for its dense wood and rich bark. The whole plant is packed with polyphenols, tannins, flavonoids and minerals, a mix that gives the extract its natural protective powers. Centuries ago the bark was steeped in water for folk remedies that cleansed skin and calmed minor irritations. Modern formulators noticed those same properties, refined the extraction process and introduced the ingredient to skin and body care lines.
To make the extract, harvested branches, leaves and bark are cleaned, dried and milled, then soaked in water or a gentle alcohol solution. The liquid is filtered, concentrated and blended into a stable carrier such as glycerin so it mixes smoothly into creams and gels. This gentle, low-heat method helps preserve the oak’s delicate phenolics that give the final product its skin-loving benefits.
You will often spot Quercus Acutissima Extract in facial masks that soothe and purify, daily moisturizers that balance oil and water levels, lightweight serums aimed at redness relief, deodorant creams and sprays that fight unwanted odor, scalp tonics that refresh the roots and even aftershave lotions that calm post-shave skin.
Quercus Acutissima Extract’s Cosmetic Benefits/Uses

- Emollient: Light oils naturally present in the plant smooth the skin’s texture giving a soft touch without a greasy feel
Who Can Use Quercus Acutissima Extract
This oak extract is gentle enough for most skin types. Normal, oily and combination complexions benefit from its balancing and antimicrobial properties while sensitive skin often appreciates its soothing polyphenols. Very dry skin can still use it but may need a richer cream alongside because the extract itself is not highly occlusive.
Because it is derived entirely from a plant with no animal by-products or processing aids, products featuring Quercus Acutissima Extract are suitable for both vegans and vegetarians.
No data suggest the ingredient poses a special risk to pregnant or breastfeeding women when applied topically in cosmetic amounts. That said this is not medical advice, and anyone who is pregnant or nursing should show the full product ingredient list to a healthcare provider for personalized guidance.
The extract does not make skin more sensitive to the sun so there is no added photosensitivity concern. It also layers well with most common skincare actives such as niacinamide, hyaluronic acid and gentle exfoliating acids.

Comedogenic Rating
Rating: 1/5
Quercus Acutissima Extract is largely water soluble and contains only trace lipids so it does not leave a heavy film that can trap sebum. Its tannin content even offers a mild astringent effect that helps keep pores clear. A tiny amount of natural plant wax keeps the rating from being a perfect 0 yet the chance of clogging remains very low.
Most acne-prone skin can use this ingredient without worrying about extra breakouts.
The final pore-clogging risk depends more on the other components of the formula, not the oak extract itself.
