Ingredient review
Hassaku/Natsudaidai Peel Powder
INCI: CITRUS HASSAKU/NATSUDAIDAI PEEL POWDER
A gentle powdered exfoliant from citrus peels that can brighten skin but may cause irritation for sensitive types.
In plain English
This is a finely ground powder made from the dried peel of two Japanese citrus fruits: Hassaku and Natsudaidai. When mixed with water, the tiny particles help physically buff away dead skin cells, leaving skin smoother. The peel also contains natural antioxidants like vitamin C and flavonoids that can help protect skin from environmental damage. However, because it's a citrus-derived ingredient, it may be slightly acidic and could cause stinging or irritation for those with very sensitive skin or compromised barriers.

What it is
A powdered ingredient made by drying and grinding the peel of Citrus hassaku and Citrus natsudaidai fruits. It contains natural fibers, essential oils, and antioxidant compounds.
How it works
In a cosmetic product, the powder acts as a mild physical exfoliant when rubbed against the skin.

Cons and cautions

Citrus peel contains compounds that can make skin more sensitive to UV light, so it's important to use sunscreen if using products with this ingredient.
