The Ordinary 100% Plant-Derived Squalane 30ml – Lightweight Skin-Identical Face & Hair Oil Pure Sugarcane Squalane Seal Step

✨ Key Benefits✔️ 100% Plant-Derived Squalane (Sugarcane Source):​ INCI is one word—Squalane. Hydrogenated form of squalene (the 12%-of-human-sebum lipid), so skin recognizes it as "self." Unlike squalene (with an e) which oxidizes rancid in weeks, squalane (with an a) is saturated, photostable, odorless, and won't go crayon-smelling like rosehip. ECOCERT-approved + USDA Bio-based.✔️ Skin-Identical Lightweight Occlusive:​ Not a humectant (adds no water), not a treatment (no C/A/peptides)—it's a pure emollient seal. Reduces TEWL within days, softens without petrolatum heaviness, and because it mimics sebum, even oily skin tolerates 2 drops (comedogenicity 0–1/5, signals skin to ease compensatory sebum over 4–6 weeks).✔️ Retinoid/Exfoliant Buffer Without Interfering:​ TO explicitly says apply after water-based treatments to lock them in and buffer retinoid/BHA/AHA dryness—without lowering their efficacy (no pH change, no enzyme clash). This is why it sits next to LRP B5+ in retinoid routines, but lighter.✔️ Multi-Use Beyond Face:​ Few drops on hair ends = heat protection + shine + less breakage; on cuticles/lips/cracked heels it works as a neutral balm. One bottle, face+body+hair.✔️ Alcohol-Free / Oil-Free (TO's definition: no triglyceride plant oils) / Silicone-Free / Fragrance-Free / Essential-Oil-Free / Vegan / Gluten-Free:​ Phenoxyethanol absent (anhydrous oil needs none). Fungal-acne safe (saturated hydrocarbon, Malassezia can't metabolize it—unlike oleic-rich oils). The most inert product in your entire 30-piece deck.✔️ Stable & Forgiving:​ 6–12M PAO, amber glass, no refrigeration. Won't oxidize from one forgotten cap-close. Cheaper (~$10–13/30ml) than Biossance/Timeless for the identical molecule.🧴 How to UseWhen:​ AM and/or PM, final anhydrous step​ after all water-based serums and creams (or mixed into them).Amount:​ 2–3 drops face; 1 drop oily skin; +1 drop for neck/hair ends.Apply:Press method:​ Warm in palms, press onto dry-ish skin over Panthenol Gel / B5+ / NMF. Don't rub—press.Mix method:​ 1–2 drops into LRP B5+ or NMF+HA in palm → thins balm, less occlusive.Retinoid nights:​ Retinoid → Pink Serum → Panthenol Gel → Squalane 2 drops press​ = classic buffer (retinoid renews, squalane seals, no sting).AM under SPF:​ Squalane → wait 5 min → TO Mineral/SKIN1004/Facetology/Wawa SPF. Can pill if you over-pour; 2 drops max AM.Never​ as first step on bare cleansed dehydrated skin—no water in it, seals in dryness. Always layer over Marine/AAB5/Panthenol Gel first.Routine Integration:PM seal (every night):​ Cleanser → Milky → Marine/AAB5 → Buffet/377/Eucerin → (retinoid 2×/wk or Mandelic rotate) → Pink Serum → Panthenol Gel → TO Squalanevs Rosehip Oil (previous entry):​ Rosehip = unsaturated nutritive oil with A-precursors/linoleic (treatment oil, slower, oxidizes); Squalane = saturated inert seal (no actives, stable, universal). Stack: Squalane all-over press, Rosehip 1 drop on PIE/scar zones only. Or alternate seasons (squalane summer, rosehip winter).vs LRP B5+:​ B5+ = occlusive balm with panthenol/cera for barrier-collapse; Squalane = pure lipid seal for daily maintenance. B5+ on peeling zones, Squalane overall.vs TO Milky Toner (has squalane):​ Milky Toner's squalane is emollient in a water phase (prep step); this is 100% pure oil (seal step). Not redundant—toner prep, pure oil seal.Patch Test:​ Jawline 24h; allergy essentially nil, but olive-source squalane can carry trace olive protein—TO uses sugarcane, so severe olive allergy safer here.Consistency:​ Immediate softening; TEWL drop at 1 week; barrier comfort 2–4 weeks. Not a treatment—no pigment/line change alone, but makes every serum under it work better by stopping evaporation.💡 Ideal ForAll skin types including oily/acne-prone (2 drops, comedogenic 0–1), sensitive, pregnant, post-procedure, fungal-acne users.Retinoid/BHA/AHA users wanting a neutral buffer that won't clash with anything.People who found rosehip "too active/heavy/oxidizes" and want a do-nothing-but-seal oil.Multi-taskers: face + hair ends + cuticles from one bottle.Not ideal for:​ Expecting brightening/anti-spot/line-erase (it's inert—pair with 377/Eucerin/Buffet for that); dehydrated skin using it alone (must layer over humectant); users wanting a "skincare oil with vitamins" (rosehip is that, squalane isn't); those who hate any oil film AM under makeup (use 1 drop PM only).
