What Is Quercus Salicina Stem Extract?
Quercus Salicina Stem Extract comes from the stems of the Quercus salicina tree, an evergreen oak native to East Asia. The stem tissue is naturally rich in polyphenols, tannins and flavonoids, compounds known for fighting oxidation and microbes. Traditional bath and skin rituals in Japan and Korea have long relied on oak infusions to soothe skin and help keep it clean; modern formulators tapped into this heritage and began refining the extract for use in creams and hair care in the early 2000s.
To make the extract, cleaned and chopped stems are steeped in a food grade solvent such as water or a water-ethanol mix. The liquid is then filtered and concentrated before being gently dried or pasteurized, leaving a stable, amber-colored concentrate that blends easily with oils and water bases.
You will spot Quercus Salicina Stem Extract in clarifying toners, sheet masks, lightweight moisturizers, anti aging serums, soothing after-shave balms, scalp treatments and strengthening conditioners. Its balanced profile makes it equally useful in rinse-off and leave-on products.
Quercus Salicina Stem Extract’s Cosmetic Benefits/Uses
This multitasking plant extract offers several benefits when added to skin or hair formulas
- Antimicrobial: Helps curb the growth of odor-causing or breakout-triggering microbes which supports cleaner skin and longer product shelf life
- Antioxidant: Neutralizes free radicals created by UV light and pollution helping reduce early signs of aging such as dullness and fine lines
- Astringent: Gently tightens the look of pores and reduces excess oil giving skin a fresh matte finish without over-drying
- Hair Conditioning: Smooths the cuticle to boost shine and manageability while also calming an irritated scalp
- Emollient: Adds a light, silky layer of moisture that softens skin and reduces rough texture
Who Can Use Quercus Salicina Stem Extract
The extract’s balanced mix of antioxidants and gentle astringents makes it suitable for most skin types including oily combination and normal skin. Dry or mature skin can also benefit thanks to its light emollient action though these users may prefer it paired with richer moisturizers. People with very sensitive or barrier-impaired skin should introduce it gradually as the natural tannins can feel slightly tightening if the formula is highly concentrated.
Quercus Salicina Stem Extract is plant derived with no animal by-products or animal testing required so it aligns with vegan and vegetarian lifestyles.
No data suggest the extract poses a specific risk to women who are pregnant or breastfeeding when used topically in cosmetic strengths. This is not medical advice and anyone who is expecting or nursing should check with a physician before adding new skincare just to be safe.
The ingredient is not known to cause photosensitivity and does not make skin more prone to sunburn. Standard daytime sunscreen use is still recommended as part of any routine.

Comedogenic Rating
Rating: 1/5
Quercus Salicina Stem Extract is mostly made up of water soluble polyphenols and tannins with only trace lipids, so it does not readily clog pores. Its gentle astringent effect can even help keep pores clearer by reducing excess surface oil. Because of this low comedogenic score it is generally well suited for acne-prone or breakout-prone skin. Only formulas that pair the extract with heavy occlusive oils could raise the pore-clogging potential, so always look at the full ingredient list when assessing a product.
Summary
Quercus Salicina Stem Extract works as an antimicrobial antioxidant astringent light emollient and hair conditioner. Polyphenols and tannins fend off bacteria and free radicals while gently tightening skin and adding a silky feel. In hair care the same compounds smooth the cuticle calm the scalp and boost shine.
While not yet a household name the extract is quietly gaining followers in Asian beauty lines and indie formulations thanks to its multitasking profile and clean botanical origin.
Current research and decades of traditional use suggest the ingredient is safe for topical use with only rare mild reactions reported. As with any new skincare component it is wise to do a small patch test before full application to make sure your skin agrees with it.
