What it is
The Ordinary Retinol 1% in Squalane is a high-strength retinol serum that delivers pure retinol—vitamin A in its most studied form—suspended in squalane, a lightweight, skin-identical emollient. At a full 1% concentration, this sits at the top of The Ordinary's retinol range, making it a serious anti-aging and pigmentation treatment rather than a gentle introductory formula. The minimalist ingredient list keeps the focus squarely on the active, with squalane serving as a carrier that improves skin feel and helps offset some of the dryness retinol can cause.
Who it's for
This serum is best suited to experienced retinol users who have already built tolerance with lower concentrations (0.2% or 0.5%) and want to step up their results. It works across skin types—oily, combination, and normal—and is particularly useful for those dealing with fine lines, wrinkles, post-acne dark spots, or an uneven, dull complexion.
You should skip this formula if you are new to retinol, have active rosacea or eczema, or have highly reactive skin—1% is potent enough to cause significant purging and irritation in sensitive skin. It is not appropriate for use during pregnancy or while breastfeeding. Anyone currently using prescription retinoids should not layer this on top without guidance from a dermatologist.
How to use it
Use this serum at night only. Retinol degrades in sunlight and increases photosensitivity, so daytime application is counterproductive and potentially harmful. Apply to clean, fully dry skin—moisture on the skin surface speeds absorption and amplifies irritation risk. A pea-sized amount is enough for the full face.
If you are new to this concentration, start with one to two nights per week and hold that frequency for four to six weeks before increasing. This slow introduction, sometimes called the sandwich method when paired with a plain moisturizer above and below, gives skin time to upregulate its tolerance. In your routine, this goes after any water-based serums and before a plain moisturizer or face oil. Follow every morning—without exception—with a broad-spectrum SPF 30 or higher.
Key ingredients
Retinol (1%) is a form of vitamin A that converts to retinoic acid in skin. It accelerates cell turnover, which helps resurface dull, uneven texture; it also stimulates collagen production over time, which is the mechanism behind its effect on fine lines and wrinkles. Consistent use can gradually fade dark spots by speeding the shedding of pigmented surface cells. Results from retinol are cumulative and typically become visible after 8–12 weeks of regular use.
Squalane is a stable, non-comedogenic plant-derived oil that acts as the delivery vehicle here. It replenishes the lipid barrier, reduces transepidermal water loss, and softens the skin-feel of what would otherwise be a very stark active formula. It does not eliminate retinol-related dryness or flaking—especially early on—but it helps make the formula more tolerable than an aqueous suspension.
Pros & cons
- High active concentration at an accessible entry point for the category
- Minimalist formula with no fragrance, dyes, or unnecessary fillers
- Squalane carrier adds emollient benefit without clogging pores
- Addresses multiple concerns—texture, tone, and lines—with a single serum
- Well-reviewed by a large pool of verified buyers (4.5/5 across over 18,000 ratings)
- 1% is too strong for retinol beginners; starting here risks irritation, peeling, and barrier damage
- An adjustment period of several weeks is normal and expected—early results may look worse before they look better
- Requires consistent SPF use the following morning, which adds a step some users skip
- Not suitable during pregnancy or breastfeeding, limiting its audience
- Squalane does not fully prevent dryness; a separate moisturizer is still necessary
How it compares
This retinol serum and a basic moisturizer serve different roles in a routine rather than competing head-to-head. After applying this serum, you will still need a plain, non-active moisturizer to seal in hydration and support the skin barrier during the adjustment period. CeraVe Daily Moisturizing Lotion is a reliable, fragrance-free option that layers well over retinol serums without interfering with the active. For drier skin types that need more occlusive support overnight, CeraVe Moisturizing Cream provides a heavier barrier-repair layer that pairs logically with a high-strength treatment like this one.
The verdict
The Ordinary Retinol 1% in Squalane delivers exactly what it advertises: a straightforward, high-concentration retinol in a skin-compatible oil base. For experienced retinol users who have plateaued on lower strengths and want to target persistent dark spots, deeper lines, or chronic dullness more aggressively, this is a logical and well-formulated next step. The squalane base makes it more tolerable than a water-based formula at this strength, but it does not make it gentle—patience and a slow introduction are still essential. Pair it with a good plain moisturizer and non-negotiable morning SPF, and this is one of the more efficient high-retinol options available without a prescription.
What shoppers say
Shoppers consistently praise the squalane base for keeping skin nourished and hydrated while the retinol does its work — many note their complexion looks smoother and more radiant with regular use. Reviewers also appreciate how concentrated the formula is, reporting the small bottle lasts surprisingly long since only a tiny amount is needed per application.
The main caveat is potency: at 1%, this is considered a high-strength option best suited to those already comfortable with retinoids. First-timers and those with sensitive skin are cautioned to start slow and do their homework on proper retinol introduction before diving in.
It's less than $10, after 5½ weeks, I have 70% of the bottle left and it’s WORKING. Keep reading for my experience❣️ •photo is my "after" 5 full weeks• I couldn't find any "before" pics without makeup or sunglasses, and doesn't that just say it all ♡ I have sensitive skin, combination skin. Like many, I've tried so many products being in my late 30s. I struggle with hormonal acne, which makes skin care hard. Plus, forehead & neck wrinkles, etc. This product has clearly listed ingredients, vegan, no animal testing. Note: This particular product is 1% retinol squalane & is not necessarily for beginners. If you burn or get dry skin easily, maybe start with a lower concentration, but me being me, I wanted results and went all in. I was not disappointed! And I didn’t notice any particular smell, which I appreciate. Pro Tip: Keep in the fridge! Feels amazing and recommended on the box to extend potency. My Trial and Error! •Week 1: I skipped the recommended test patch & I started at 4 nights a week. Maybe a little ambitious😅 My skin broke out with whitehead acne in not my typical zones, a bit oily, not looking like my typical zits. Ifykyk. Week 2: Did a little research, the retinol strength and quality literally pushed all dead skin, imperfections, embedded dirt/environmental junk to the surface as my skin regrowth sped up. This was causing those whiteheads as impurities purged. This is normal for retinol products (according to multiple sources.) So I slowed down a bit to twice weekly. I still lightly broke out with a few pimples, but it was gone in a day or 2. Meanwhile, I’m already noticing fine lines improving, a better glow and overall my skin doesn’t look so flat/dull. Hydration— I’d say A for combo skin. Maybe use a little less for oily skin or check out The Ordinary website for routine-building options. Week 3: I’m in the zone integrating into my skin care routine. Personally, I use this product at night after cleanser and alcohol-free toner (not The Ordinary brand, but products that work for me and I trust). I use less than one dropper for my whole face and neck. The serum needs to be totally dry and absorbed. then finish with moisturizer. Halfway through Week 3 I add an extra night. Week 4: I’m at 3 nights a week. Occasional whiteheads. *To be clear! my hormonal acne didn’t change at all, there’s a difference. Retinol doesn't target acne so i didn't expect any change there* Noticeably reduced fine wrinkles on my forehead, my skin tone seems more even, my face looks less flat and more healthy. Some of my self-loathed deep lines look better. Best of all, I FEEL better. Up to 4 nights a week. Week 5: Personal life was rough, routine not as consistent but skin still looks good. Not like one of those creams where you miss a day and you’re back to ground zero. I did 2 days that week. Week 6: I’m actively building a better skin care nightly routine using The Ordinary, but still keeping a few other brand products I love. My 17-year-old son actaully NOTICED, and my favorite barista told me I had a “glow.” 🫶🏽 I can’t wait to try the Niacinamide serum next! **hit the thumbs up if this review helped you please!**
Read on Amazon ↗I've always heard of "anti-aging" skincare. After buying some budget friendly products with this claim, I believed only the crazy expensive stuff would actually work as advertised. Then I bought this. The Ordinary retinol 1% in squalane has been an absolute game changer for my oily, acne prone skin. It's always rough and dull, and the pores around my T-zone are always huge. This product has made my skin very smooth and I notice my pores are a little smaller. WARNING: Do NOT use on skin around the eyes. No matter how I tried to ease my way to applying in that area, the skin always ended up very dry and even burned. It took a whole week for the burn to go away, and applying anything on that area stung like crazy. You would be better off buying a retinol product specifically for the eye area. Also, remember to store in the fridge. As long as I waited for the product to absorb before applying moisturizer, my skin did not get greasy. I also do not notice any fragrance. I 100% recommend this product, but PLEASE do your research on retinol before using it, or you will do more harm than good to your skin. I definitely learned the hard way.
Read on Amazon ↗I've used retinoids before, and this 1% Retinol in Squalane is definitely one of the strongest options from The Ordinary. The squalane base helps reduce dryness and leaves my skin feeling nourished while still delivering the benefits of retinol. With consistent use, my skin looks smoother, more even, and refreshed. If you're new to retinol, start with a lower strength first, but for experienced users looking for a stronger formula, this is an excellent option at a great price. ✨ A little goes a long way, and don't forget sunscreen during the day! 🌞💕
Read on Amazon ↗I recently purchased this basically as a step above the good molecules beginner retinol and a step below prescription retinoids. The squaline give my skin a gorgeous glow and hydrates so well. It’s a thin oil feel so it was hard to apply at first since a little goes a long way but once you know what your skin needs it’s easy to apply. It’s effective. The first week I could tell it was casing purging. I’m excited to see what’s to come. I already see a huge difference in pores. The bottle is full so it’s certainly going to last a long time. Especially since I only use it every other day.
Read on Amazon ↗Comes in a small no-frills bottle. Goes on easily and has an oily feel while applying, so not much is needed each time. Product lasts a long time. Works better than some of the more expensive brands I've tried. My skin looks great and feels soft in the morning. Note: In very small letters it says that the product should be refrigerated.

The Ordinary Retinol 1% in Squalane Serum: frequently asked questions
What does The Ordinary Retinol 1% in Squalane do?
This serum delivers 1% pure retinol — a high-strength vitamin A derivative — suspended in squalane, a lightweight emollient oil. Retinol works by accelerating cell turnover to visibly reduce fine lines, wrinkles, dark spots, and uneven skin tone over time.
The squalane base serves as a buffer, helping offset some of the dryness and irritation commonly associated with retinol, while also preventing the formula from feeling stripping or tight on the skin.
Who should use The Ordinary Retinol 1% in Squalane?
At 1%, this is The Ordinary's highest retinol concentration and is best suited for those who have already built tolerance with lower-strength retinoids (0.2% or 0.5%). It's a reasonable starting point from your mid-20s onward — retinol has no age ceiling, and beginning in your 40s or later can still deliver meaningful improvements in texture, tone, and fine lines.
If you have sensitive or reactive skin, start with a lower concentration and work up gradually to reduce the risk of irritation.
What should you not mix with retinol in the same routine?
Avoid layering this serum with AHAs (glycolic, lactic acid), BHAs, or vitamin C in the same application — combining strong actives increases the risk of irritation, redness, and a compromised skin barrier. Benzoyl peroxide can also degrade retinol and reduce its effectiveness.
A practical approach: use retinol at night on its own, and save acids or vitamin C for your morning routine, or alternate evenings to let your skin adjust.
Do I need a moisturizer after applying retinol in squalane?
Yes. While the squalane base adds some emolliency and helps limit water loss, it's not a substitute for a full moisturizer — particularly at 1% strength, which can cause noticeable dryness and flaking as your skin adjusts. Following with a barrier-supporting cream significantly improves tolerance.
A fragrance-free option like CeraVe Moisturizing Cream layers well over retinol serums without pilling and helps reinforce the skin barrier overnight.
Does squalane clog pores?
Squalane is broadly considered non-comedogenic and is generally well-tolerated even by oily or acne-prone skin types. It closely mimics the skin's own lipids and absorbs without leaving a heavy, greasy residue — unlike some heavier plant oils that can cause congestion.
Individual responses always vary, so if you're particularly prone to clogged pores, patch-test the serum on a small area for a week before applying it to your full face.
Does The Ordinary Retinol 1% in Squalane help with acne scars and dark spots?
Retinol can improve the appearance of post-acne marks, hyperpigmentation, and dullness over time by speeding up cell turnover and bringing fresher skin to the surface. This serum's 1% concentration makes it one of the more effective OTC options for targeting uneven tone and texture.
Results are gradual — expect several weeks to a few months of consistent use before seeing meaningful change. Note that this is not a spot treatment for active breakouts; it works best as part of a nightly preventative and corrective routine.
