Ingredient review
Citrus Unshiu Peel Powder
INCI: CITRUS UNSHIU PEEL POWDER
A gentle, natural exfoliant from mandarin peel that also provides antioxidant protection, but research on its cosmetic benefits is still limited.
In plain English
Citrus Unshiu Peel Powder is made by drying and grinding the peel of Satsuma mandarins (a type of seedless citrus). In skincare, the fine particles help slough off dead skin cells for a smoother complexion, while the peel's natural compounds may help protect skin from environmental damage. It's a milder alternative to harsher physical exfoliants like walnut shell powder.

What it is
A finely ground powder derived from the dried peel of Citrus unshiu, also known as the Satsuma mandarin or mikan. It contains natural fibers, essential oils, and antioxidant flavonoids like hesperidin.
How it works
The powder's physical texture provides gentle mechanical exfoliation, removing dead skin cells when massaged onto the skin. Additionally, flavonoids in the peel may offer antioxidant activity, helping to neutralize free radicals that can cause premature aging.
Pros
Gentle exfoliation
The fine powder provides a mild physical scrub that is less abrasive than many nut shell powders, making it suitable for regular use on most skin types.
Natural antioxidant source
Contains flavonoids like hesperidin that may help protect skin from oxidative stress, adding a functional benefit beyond exfoliation.
Cons and cautions
Limited research
Most evidence for its antioxidant benefits comes from general citrus peel studies, not specifically from topical use of this powder in skincare.
Potential for irritation
Citrus peels contain natural acids and essential oils that may cause stinging or redness on sensitive or compromised skin.
Best for
- Those looking for a natural, gentle exfoliant
- People with normal to combination skin who want a mild scrub
Use caution if
- Individuals with citrus allergies
- Those with very sensitive or broken skin
