Keep out of reach of children. ## What the research says - Corsican helichrysum's neryl acetate and related constituents have been studied for antioxidant and other activities in the laboratory. Its 'skin repair' reputation is popular and traditional, not established by strong clinical evidence. — PLOS ONE study (2022) (https://doi.org/10.1371/journal.pone.0268384) ## Evidence - Corsican helichrysum is defined by neryl acetate as its major constituent, alongside curcumenes and the distinctive italidione diketones — the Corsican type being the most prized. — PLOS ONE study (2022) (https://doi.org/10.1371/journal.pone.0268384) ## Frequently asked questions ### Why is Corsican helichrysum so prized? Corsica is regarded as the benchmark origin for Helichrysum italicum, valued for a particularly fine, ester-rich oil. Combined with the plant's very low yield, that makes genuine Corsican helichrysum one of the most expensive essential oils. ### Is it good for skin? It's popular in skincare and generally gentle, but its 'skin repair' and bruise reputation is largely traditional. Enjoy it as a soothing addition to a diluted blend rather than a proven treatment. ### Is Corsican helichrysum phototoxic? No — it isn't phototoxic. Dilute it for skin use, but there's no sun-exposure restriction. ## Sources (GC-MS studies) - Glumac M, Jažo Z, Paštar V, Golemac A, Čikeš Čulić V, Bektić S, Radan M, Carev I.
