What Is Castanea Crenata Pellicle Extract?
Castanea Crenata Pellicle Extract comes from the thin brown skin that lines the inside of the Korean chestnut shell. After the nuts are harvested the pellicles are separated, dried and finely milled before being soaked in a mix of water or gentle solvents. The liquid is then filtered and concentrated, yielding an amber toned extract rich in naturally occurring polyphenols, tannins, flavonoids, sugars and trace minerals.
Chestnut skins have long been used in East Asian folk care for their ability to soothe skin and control excess oil. As Korean beauty products gained worldwide attention formulators took a fresh look at this by-product of the food industry and refined it into a stable cosmetic ingredient. Today the extract appears in toners, essence pads, sheet masks, anti aging serums, lightweight moisturizers, scalp refresh sprays and natural deodorant sticks.
Castanea Crenata Pellicle Extract’s Cosmetic Benefits/Uses
This multitasking botanical supports a range of skin and hair goals
- Antioxidant: The high polyphenol content helps neutralize free radicals created by UV light and pollution which can dull skin and speed up visible aging. Added to daily care formulas it supports a brighter, more even tone
- Astringent: Chestnut tannins create a gentle tightening effect that can reduce the look of enlarged pores and curb excess sebum making the extract popular in toners and lightweight gels for combination or oily skin
- Deodorant: Its natural odor-absorbing compounds help inhibit the growth of odor-causing bacteria so the extract is often included in underarm products and scalp mists for a clean fresh feel
Who Can Use Castanea Crenata Pellicle Extract
Most skin types tolerate this chestnut-derived ingredient well. Its lightweight water-soluble nature suits oily and combination skin because it helps temper excess sebum, yet it still offers antioxidant support that benefits normal and mature skin. Very dry or highly sensitive skin may want to pair it with richer moisturizers, as the natural tannins can feel a little tightening if used alone in high concentrations.
Because the extract is 100% plant sourced and generally processed without animal derivatives it aligns with vegan and vegetarian values. Those following cruelty-free lifestyles should still check a finished product’s overall certification, but the extract itself is considered animal friendly.
Current research shows no specific risks for women who are pregnant or breastfeeding when the ingredient is used topically at the low percentages found in cosmetics. This is not medical advice; expectant or nursing mothers should discuss any new skincare product with their healthcare provider to be safe.
The extract is not known to increase photosensitivity so it can be applied day or night. Standard daily sunscreen is still recommended for overall skin health.

Comedogenic Rating
Rating: 1/5
Castanea Crenata Pellicle Extract is mostly water soluble and contains minimal lipids, so it does not tend to sit inside pores or create an oily film. Its tannin content can even help cut surface sebum which further lowers clogging risk. Because of this it is generally suitable for people who are prone to acne and breakouts.
Formulation still matters: if the extract appears in a heavy cream full of rich oils the overall product may feel more pore clogging than the extract itself. Always look at the full ingredient list when assessing breakout risk.
Summary
Castanea Crenata Pellicle Extract offers antioxidant protection, gentle astringency and natural deodorizing power thanks to its polyphenols, tannins and trace minerals. The antioxidants mop up free radicals, the tannins tighten pores and absorb excess oil while antibacterial compounds curb odor causing bacteria.
Once a humble by product of the Korean chestnut industry the extract has gained steady popularity with the rise of K beauty yet it is still considered a niche ingredient outside Asia.
Safety studies and real world use show a low irritation profile for most users, though anyone can react to any botanical. When trying a new product that contains this extract it is smart to perform a small patch test first to confirm personal tolerance.
