What it is
This is a volatile essential oil expressed from lemon peel, dominated by limonene along with other terpenes that give a fresh citrus aroma. It is included in small amounts to scent a formula rather than for any active skincare role. It provides no UV protection.
Safety & warnings
Lemon peel oil contains fragrance allergens such as limonene and citral that can oxidize, so it may cause reactions in fragrance-sensitive skin. Cold-pressed citrus peel oils can also contain furocoumarins associated with photosensitivity, though cosmetic grades may be processed to limit these; patch testing is sensible for reactive skin.
Origin & sourcing
Natural, plant-derived. It is cold-pressed from the peel of lemon fruit.
