What it is
A plant-derived extract obtained by pressing or solvent-extracting the peel of sweet oranges (Citrus aurantium dulcis). It is rich in flavonoids, limonene, and vitamin C.
How it works
In skincare, it acts as an antioxidant, neutralizing free radicals that cause premature aging. Its mild astringent properties can temporarily tighten pores and reduce excess oil. The limonene content also provides a natural citrus fragrance.

Cons and cautions
Potential skin irritation
Natural citrus acids and essential oils can cause stinging, redness, or irritation, especially on sensitive or broken skin.
Fragrance allergen risk
Limonene, a major component, can oxidize and become a sensitizer, potentially triggering allergic reactions in some users.

Usage tips
Safety summary
Generally safe for most skin types when used at typical cosmetic concentrations. However, due to its natural acids and limonene content, it poses a moderate irritation risk for sensitive skin and a low risk of photosensitivity. Avoid applying to broken or sunburned skin.
Research notes
Studies confirm the antioxidant activity of citrus peel extracts, attributed to flavonoids and vitamin C. Research also notes potential skin irritation from limonene, especially after oxidation. Evidence is moderate, with most studies being in vitro or small human trials.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. The EU CosIng database lists it as a skin-conditioning agent. Limonene is required to be listed as an allergen on EU labels when present above certain thresholds.
- Common uses
- Serums, Moisturizers, Toners, Cleansers
- Environmental note
- Orange peel is a byproduct of the juice industry, making this extract a relatively sustainable choice. However, conventional citrus farming may use pesticides, so organic sourcing is preferable.
Good to know

- The peel contains more antioxidants than the juice
- Look for products with added antioxidants like vitamin E to stabilize the extract
