The Ordinary RETINOL 1% IN SQUALANE 30ML

Values: 100% Genuine (Adilsons policy) · Fragrance-Free (confirmed via INCI) · Vegan-Friendly*. No Pregnancy-Safe badge — see the safety notice above.

Pros: genuinely one of the highest over-the-counter retinol concentrations available, water-free formula resists oxidation, real antioxidant stabilizers protect the active. Caveats: a real, well-documented purge/irritation risk on first use, not appropriate as a first retinoid, contraindicated in pregnancy, conflicts with prescription retinoids, and this exact SKU shows limited stock (6 units) at Adilsons.

RED — not for under 16, and realistically not appropriate for most under-25s either, since this is the highest-strength product in an already-advanced category, reserved for skin with established retinoid tolerance.

Step 1 (When): PM only, on fully dry skin, only after you've already built tolerance on a lower-strength retinol. Step 2 (How much): 2-3 drops, starting at once weekly. Step 3 (How): pat in gently, wait 20-30 minutes before moisturizer.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

1. Double cleanse if wearing SPF/makeup. 2. Wait until skin is fully dry. 3. Retinol 1% in Squalane — 2-3 drops, on the scheduled night only. 4. Moisturizer, generously.

Skin cycling placement: in a 4-night cycle, this occupies the Retinoid night, preceded by an Exfoliation night and followed by two full Recovery nights — at this strength, do not compress the recovery window even if you feel fine.

AM restriction: this is strictly a PM-only product. Retinol increases photosensitivity, and at 1% concentration this effect is more pronounced than at lower strengths.

SPF mandate: strict SPF50+ PA++++ every single morning is non-negotiable at this strength — skipping it even once significantly raises sunburn and long-term sun-damage risk.

Technique: pat, don't rub. Skin state: fully dry skin, at least 20-30 minutes after cleansing. Wait time: 20-30 minutes before moisturizer, longer if you notice any tingling. The "sandwich method" (a thin layer of moisturizer before and after) is a legitimate way to buffer this strength if irritation is a concern.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Global rules: viscosity ladder thinnest-to-thickest, water-phase before oil-phase, treatments before seals. Retinoids specifically: apply on fully dry skin, wait 2-5 minutes (longer at this strength) before moisturizer. If a routine pills, stings, or feels heavy, reduce layers, never increase them.

PM Maximum Stack: (1) micellar/oil cleanse if needed, (2) water cleanser, (3) wait until fully dry, (4) anchor active — this retinol, on its scheduled night only, (5) moisturizer, generously, (6) occlusive seal if very dry. Do not layer retinoids with AHA/BHA in the same night; keep one lane per night.

This product does not appear in the AM stack at all — it is PM-only, full stop.

Rest days required: at minimum 2-3 full recovery nights between applications, even for established retinoid users. Overuse warning: at 1%, exceeding your tolerance does not just risk mild flaking — real, documented purge/irritation episodes (redness, itchy bumps across the face) have been reported by users who moved too fast at this exact strength.

Purging vs. reaction: purging (usual breakout zones, improving within 4-6 weeks) is plausible at this strength; a genuine reaction — new areas, hives, severe burning, worsening rather than improving — means stop immediately and follow the 72-Hour Barrier Reset below.

Before starting this product, your routine must already include months of confirmed tolerance on a lower-strength retinol (0.2% or 0.5%), a daily SPF habit, and a working moisturizer.

Barrier index gate: if your skin stings on moisturizer or feels tight within 30 minutes of cleansing, your barrier is below threshold — this is not the product to push through that with. Repair first with something like Anua Birch Moisture Boosting Cream.

Established fine lines and texture: at 1%, retinol delivers a more pronounced acceleration of epidermal turnover and collagen-signaling activity than lower strengths, producing more visible change in texture, tone, and fine lines for skin that can tolerate it. What this product cannot do: it cannot lift sagging skin or remove deep, established wrinkles — and pushing frequency to chase faster results only produces irritation, not better outcomes.

Sunscreen (absolutely mandatory, no exceptions): primary pick Beauty of Joseon Relief Sun SPF50+. Alternatives: SKIN1004 Hyalu-Cica Water-Fit Sun Serum, Anua Heartleaf Silky Moisture Sun Cream, MIXSOON Cica Hyal Sunstick.

Rich barrier-support moisturizer (mandatory companion): primary pick Anua Birch Moisture Boosting Cream. Alternatives: Anua Peach 77% Niacin Conditioning Milk, Beauty of Joseon Calming Serum.

Non-competing peptide support (off-nights only): primary pick The Ordinary Matrixyl 10% + HA.

This is a conflict-solver for ACTIVE ingredients. If you run multiple actives, use these rules to avoid irritation, deactivation, and barrier damage.

× AHAs (glycolic/lactic/mandelic): never the same night at this strength — use skin cycling with generous recovery nights, or fully alternate nights.

× BHA (salicylic acid): avoid the same night — use BHA on non-retinoid nights only, or split AM BHA / PM retinol.

× Benzoyl Peroxide: do not layer — BPO can oxidize/deactivate retinol, and the double irritation risk at 1% is significant.

× L-Ascorbic Acid Vitamin C: don't layer in the same routine — split AM Vitamin C / PM retinol.

× Prescription retinoids (tretinoin, adapalene, isotretinoin): if you are currently prescribed any of these, do not add this product without your dermatologist's explicit guidance — this is genuine, meaningful over-dosing on the same active pathway, not a minor overlap.

Close rule: do not layer retinoids with AHA/BHA in the same night; keep one lane per night.

MYTH: "Jumping straight to 1% gets results faster." REALITY: skin that hasn't built tolerance on a lower strength first is far more likely to have a genuine irritation episode at 1%, which sets you back weeks compared to a properly staged introduction.

MYTH: "More retinol is always better." REALITY: once your skin is responding well at a lower strength, moving up doesn't necessarily improve results proportionally — it mainly raises irritation risk.

Mauritius tap water hardness varies by region; since this is an anhydrous PM serum applied to fully dry skin, hard water residue is a cleansing-step concern rather than one for this product.

Full INCI: Squalane, Caprylic/Capric Triglyceride, Simmondsia Chinensis (Jojoba) Seed Oil, Retinol, Solanum Lycopersicum (Tomato) Fruit Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Hydroxymethoxyphenyl Decanone, BHT. [--- Estimated 1% Line ---] Solanum Lycopersicum (Tomato) Fruit Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Hydroxymethoxyphenyl Decanone, BHT.

Confirmed directly via INCIDecoder for this exact 1% strength — not extrapolated.

Preservative system: anhydrous (water-free) formula; BHT functions as an antioxidant stabilizer here, not a microbial preservative.

Fragrance status: Fragrance-Free, confirmed via INCI. Scent: a faint, natural oil-and-plant-extract smell is normal — not a fragrance additive. EU 26 allergen screen: none detected. Alcohol disclosure: Alcohol-Free.

Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars.

Vegan: *Self-assessed by Adilsons based on available INCI data. Squalane in this product is plant-derived — no animal-derived ingredients detected. This is NOT a formal vegan certification.

Cruelty-Free: *Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit in this research pass. *The Ordinary's parent company entered Mainland China retail (Sephora China) in February 2025, where post-market animal testing may apply by law; cross-border e-commerce sales may be exempt.

Microplastic status: Microplastic-Free — no synthetic film-forming polymers detected in the declared INCI.

MFDS Classification: Not applicable — Canadian brand, not MFDS-registered. Clinical evidence: retinol's mechanism is among the most extensively studied in dermatology; the specific 1%-strength irritation/purge pattern is additionally corroborated by multiple independent community accounts for this exact SKU, not just ingredient-level theory. Evidence confidence: High for the ingredient class and the real-world tolerance pattern.

Fungal Acne Safety: FA-Safe based on the declared INCI — squalane and jojoba oil are widely considered non-feeding by current FA trackers.

Assessment: Low. Oil-phase, applied last before moisturizer.

Mitigation: apply to fully dry skin, use a light hand, let it absorb before layering moisturizer.

Fresh formula is pale yellow; darker/brownish color or a rancid smell signals oxidation — discard if this occurs.

Storage: keep tightly capped, away from direct light and heat — retinol is genuinely light- and air-sensitive.

Patch test: inner forearm 24 hours, then behind the ear 24 hours, before full-face use — do not skip this step at this strength even if you've used lower-strength retinol before.

72-hour barrier reset (if reaction occurs): stop all actives. For 72 hours, use only a gentle cleanser and plain moisturizer plus mineral SPF — no acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care.

Pregnancy alternatives (verified in-catalog): if you are pregnant, nursing, or planning to become pregnant, consider The Ordinary Matrixyl 10% + HA (peptide-based, no retinoid) or SKIN1004 Probio-Cica Bakuchiol Eye Cream (bakuchiol, a plant-derived retinol-alternative) instead of this product.

1. Using this as a first retinol instead of graduating up to it. 2. Starting at more than once weekly. 3. Applying to damp skin. 4. Skipping SPF the next morning. 5. Combining with a prescription retinoid without medical guidance.

Textile note: because this is an oil-based product, avoid applying right before pressing your face into a pillow for 20-30 minutes — a silk or frequently-washed pillowcase reduces product transfer and buildup.

At 2-3 drops per use, once weekly to start (up to 2-3x/week for well-established users), a 30ml bottle lasts roughly 5-8 months.

Using more per application or more often than your current tolerance allows does not speed up results — it accelerates irritation. Reorder about two weeks before you expect to run out.

This retinol's job is the most concentrated turnover-acceleration in this catalog's Ordinary lineup — used on a conservative, scheduled cadence, never AM, never with another acid the same night.

PM (scheduled nights only, once weekly to start): cleanser → wait until fully dry → this retinol → moisturizer, generously. AM (every day): cleanser → moisturizer → SPF50+.

If you are a first-time retinoid user, do not start here — go to Retinol 0.2% in Squalane first. If you're pregnant or nursing, do not use this product at all — see the pregnancy alternatives above.

After purchasing, you will receive our skincare education email series covering this product in depth. The recommendations above are based on formulation synergy with Retinol 1% in Squalane, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

If you haven't built tolerance to retinoids yet, The Ordinary Retinol 0.2% in Squalane is the correct starting point, not this product. If retinoids don't agree with your skin at all, The Ordinary Matrixyl 10% + HA offers a retinoid-free peptide alternative.

Choose Retinol 1% in Squalane over the 0.2% starting strength if you need: more pronounced turnover acceleration after genuinely exhausting the benefit of lower strengths over months of consistent, comfortable use.

Upgrade triggers: if you have used 0.2% or 0.5% consistently for several months with zero irritation and results have plateaued, that's the signal to consider this strength — not a fixed calendar timeline.

Don't upgrade if: you're a first-time retinoid user, your barrier isn't fully settled, you're pregnant/nursing, or you're on a prescription retinoid without your dermatologist's guidance. Consistency beats complexity — most people never need to go past 0.5%.

This product's primary function is: high-strength retinoid turnover acceleration. You do not need this if you already own another open retinol/retinoid product with the same job — never run two retinoids at once, and never buy this "just in case" before confirming you actually need more than a lower strength provides.

A detailed, independent long-form review (Views In Pixels) documents a real purge/irritation episode on first use — redness, itchy bumps across the face — that resolved once frequency was reduced to 2-3x/week, after which the reviewer reported notably brighter, plumper, more even-toned skin. This pattern is consistent with broader community consensus that this strength should be a graduation point, not a starting point.

A specific Reddit thread for this exact SKU was not found in this research pass — the account above comes from an independent long-form blog review, not a Reddit thread.

Quick version: Week 1-2 — once weekly only, monitor closely. Week 3-4 — twice weekly if fully comfortable. Week 5+ — up to 2-3x/week only if genuinely well-tolerated. If irritation occurs at any point, use the 72-Hour Barrier Reset and resume at a lower frequency, not the same one.

Rule of One: this product must be introduced as the ONLY new product. Wait 14 days before adding anything else.

Retinization note: the adjustment period documented for this exact strength is temporary; reducing frequency (not stopping entirely) is the correct response unless symptoms are severe.

Decision point, end of Week 2: any redness, itchy bumps, or persistent burning? YES → drop back to once weekly for 2 more weeks, and consider the 72-Hour Reset if it's more than mild. NO → proceed cautiously to Week 3.

Can I start with this as my first retinol? No — this is the brand's highest strength and should only be used after building tolerance on 0.2% or 0.5% first.

Can I use this if I'm pregnant? No — retinoids are contraindicated during pregnancy and nursing; see the pregnancy alternatives in the Safety section.

I'm on prescription tretinoin — can I add this too? Not without your dermatologist's explicit guidance; combining two retinoid sources at this strength is genuine over-dosing risk.

Is the purging/irritation normal? A documented adjustment period is common at this strength, especially if introduced too fast — reducing frequency to 2-3x/week is the standard fix.

How long until I see results? Most experienced users report visible improvement by 8-12 weeks once past the initial adjustment period.

Best for: experienced retinoid users with genuinely confirmed tolerance on a lower strength, who are not pregnant or nursing, and who commit to a conservative, weekly-start schedule plus strict daily SPF.

Key benefits: one of the highest OTC retinol concentrations available, water-free/oxidation-resistant formulation, real antioxidant stabilizers.

Keep in mind: a real, documented purge/irritation risk on first use, not appropriate as a first retinoid, contraindicated in pregnancy/nursing, conflicts with prescription retinoids, and stock is currently limited (6 units) at Adilsons.

Assessment: Not Suitable. This is a high-strength retinoid, and retinoids are commonly contraindicated or paused during certain cancer treatments due to increased sensitivity and interaction concerns — this is not an appropriate product to introduce during active treatment without explicit oncology guidance.

Consult your oncology care team before introducing any new skincare products during treatment.
