Castor Oil Grows Nothing. What It Actually Does Is Stranger and More Useful.
No trial has ever shown it produces a single new lash — and the one adverse event with its own case literature is weirder than anything on the bottle.
Supporting role for Dullness
What Makes This Different
While most gentle cleansers either strip too much or leave residue, the Ultra Facial Cleanser threads the needle with a tri-oil system — squalane, avocado, and apricot kernel — that deposits conditioning lipids during the wash-off process. It's a foaming cleanser that behaves like a cream cleanser, which is an unusual and underappreciated formulation achievement.

A dependable, unflashy daily cleanser that earns its keep through a clever tri-oil conditioning system that prevents the tight, stripped feeling common to foaming cleansers. The SLES and paraben inclusions may give ingredient-conscious consumers pause, but the formula genuinely delivers a comfortable cleanse for most skin types.

Review
Full Review
Some products arrive with elaborate origin stories. They were developed in a French thermal spring town, or inspired by ancient beauty rituals, or formulated by a celebrity who has just discovered what hyaluronic acid does. The Kiehl's Ultra Facial Cleanser has no such story. It exists because a 170-year-old apothecary needed a cleanser to match its already beloved Ultra Facial Cream, and it needed to do one thing well: clean your face without making you regret it afterwards.
That sounds like a low bar. Anyone who has cycled through a dozen foaming cleansers that left their skin tight, dry and vaguely resentful knows it is a surprisingly difficult needle to thread. Foam comes from surfactants, and most surfactants are indiscriminate — they remove dirt, oil, makeup, and also the natural lipids your skin would very much like to keep. The Ultra Facial Cleanser answers this with what is, by cleanser standards, a genuinely thoughtful move: a tri-oil conditioning system of squalane, avocado oil and apricot kernel oil that deposits a thin layer of emollience even as the foam rinses away.
The result is a cleanser that foams without the usual consequences of foam. You get the lather, the sense of a real wash, the water running clear at the rinse — and none of the tight aftermath. It's the cleanser equivalent of having your cake and eating it, if the cake were made of squalane and smelled of nothing at all.
And it does smell of nothing, which is worth saying. Kiehl's kept this fragrance-free, a decision that reflects the pharmaceutical half of the brand's heritage rather than the botanical half. For a cleanser you use at seven in the morning, before coffee, that restraint is exactly right.
The texture is a clear, lightweight gel that needs water to wake up. There's none of the thick luxury of a cream cleanser or the bouncy jelly of newer formats — just an unpretentious gel that turns into a modest, fine-textured foam between wet palms. Thirty to sixty seconds of gentle massage, a lukewarm rinse, and it's gone completely, leaving no film and no residue.
Now the ingredients that will make some shoppers pause. The primary surfactant is sodium laureth sulfate, which occupies an awkward position in the skincare conversation — demonized by clean-beauty advocates, defended by cosmetic chemists, and in reality somewhere between the two. SLES is the milder cousin of SLS: its ethoxylated molecules are larger, penetrate less, and denature skin protein less readily. In a rinse-off product, for most skin, it's fine. The three co-surfactants alongside it — decyl glucoside, cocamidopropyl betaine, disodium cocoamphodiacetate — are all mild, and the amphoteric ones actively buffer the sulfate's irritation potential by forming mixed micelles that keep free surfactant away from the skin. It's a well-constructed blend. But for eczema, rosacea, or a genuinely broken barrier, gentler options exist and should be taken.
The preservative system includes methylparaben and propylparaben, which continue to generate consumer anxiety despite an unusually deep body of safety data. Independent review panels on both sides of the Atlantic have repeatedly affirmed their safety at cosmetic concentrations, and a rinse-off product is about the lowest-exposure format there is. That said, perception is its own kind of fact, and plenty of brands — including this one, in other lines — have simply moved on.
The ascorbyl glucoside at the tail of the list is the one piece of genuine window dressing. In a product that spends forty-five seconds on your face before going down the drain, a stable vitamin C derivative at trace level is not doing meaningful antioxidant work. It's a nice-to-have, not a reason to buy. The real value sits in the three conditioning oils.
That combination also dispatches the broader myth this cleanser was built to disprove — that foaming cleansers inevitably strip the barrier. They don't inevitably do anything. A foam that carries lipids back in as it washes lipids out behaves entirely differently from a bare detergent, and the proof of that is what your cheeks feel like ten minutes later.
As a daily driver it excels at the mundane work. It clears the overnight oil in the morning and the day's grime at night — though it will not take off heavy makeup or a stubborn sunscreen alone, and it shouldn't be asked to. Put an oil or balm cleanse in front of it on those days and let this handle the second pass. It does this, day after day, without irritation and without demanding you think about it, which is fundamentally what a good cleanser is for. One caveat for a specific group: the plant oils put it outside fungal-acne-safe territory.
At $26 for five ounces — three to four months of twice-daily use, or roughly the price of two coffees a month — it isn't budget and it isn't outrageous. The smaller travel size costs more per ounce, as travel sizes always do.
This will not transform your skin. It will not brighten, resurface, or reverse anything, and across some 1,500 reviews averaging just over four stars, nobody claims otherwise. It's a cleanser, it knows it's a cleanser, and it does cleanser things with quiet competence. In an aisle full of cleansers pretending to be serums, there's something genuinely restful about one that simply does its job and then gets out of the way.
Formula
Key Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Squalane | Provides lipid replenishment during the cleansing process, counteracting the stripping effect of the surfactant system. In a cleanser context, squalane helps ensure the skin's moisture barrier isn't compromised by the foam, leaving skin feeling soft rather than tight after rinsing. | Not yet assessed |
| Glycerin | Positioned high in the formula as the primary humectant, glycerin attracts water to the skin surface during cleansing. It works alongside the plant oils to mitigate the drying potential of the sodium laureth sulfate base, keeping this cleanser in the gentle-use territory. | Plausible mechanism for Dullness |
| Avocado Oil | A fatty acid-rich emollient that deposits a thin conditioning layer on skin during cleansing. Avocado oil's high oleic acid content makes it particularly effective at preventing the tight, stripped feeling that foaming cleansers often cause, especially on dry or mature skin. | Not yet assessed |
| Apricot Kernel Oil | Contributes lightweight emollience and a subtle skin-softening effect. In this formula, it complements the avocado oil and squalane to create a multi-oil system that keeps skin comfortable during and after cleansing without leaving a heavy residue. | Not yet assessed |
| Ascorbyl Glucoside | A stable vitamin C derivative included at the tail end of the formula to provide mild antioxidant protection. While the concentration in a rinse-off product limits its brightening potential, it offers a small boost of antioxidant defense during the cleansing step. | Not yet assessed |

Use as the second step in a double-cleanse routine in the evening, after an oil or balm cleanser removes sunscreen and makeup. In the morning, it works well as a standalone cleanser. Follow immediately with toner and serums while skin is still slightly damp.
Results Timeline
Immediate gentle cleansing without tightness from the first use. Skin feels noticeably softer and less stripped compared to harsher cleansers within the first few uses. Long-term benefits are maintenance — this is about preserving skin health rather than delivering transformative results.

Evidence
Science & Expert Perspective
The Science
The formulation strategy behind this cleanser centers on minimizing the irritation potential of its surfactant system through lipid replenishment. Squalane, a saturated hydrocarbon derived from squalene, is structurally similar to the skin's own sebum and has been shown to integrate into the lipid matrix of the stratum corneum. A study published in the International Journal of Cosmetic Science (2009) demonstrated that squalane application improved skin barrier function and reduced transepidermal water loss.
The surfactant blend itself is designed for reduced irritation: sodium laureth sulfate (SLES) has larger ethoxylated molecules compared to sodium lauryl sulfate (SLS), resulting in lower skin penetration and reduced protein denaturation. The co-surfactants — decyl glucoside, cocamidopropyl betaine, and disodium cocoamphodiacetate — are all considered mild to very mild surfactants. The inclusion of amphoteric surfactants (cocamidopropyl betaine, disodium cocoamphodiacetate) helps buffer the irritation potential of SLES through micelle interaction, creating mixed micelles with lower critical micelle concentrations and reduced monomer activity at the skin surface.
Glycerin, positioned fourth in the formula, provides humectant properties that help retain moisture during the cleansing process. A paper published in the British Journal of Dermatology has established glycerin's role in improving skin hydration and barrier repair, even in brief-contact applications like cleansing.
Dermatologist Perspective
Dermatologists frequently recommend the Kiehl's Ultra Facial Cleanser as a straightforward daily cleanser for patients who want something reliable without unnecessary complexity. Many dermatologists point out that the conditioning oil system is a thoughtful addition to a foaming cleanser, as it helps maintain barrier integrity during the cleansing step — a concern that is often overlooked in cleanser selection. However, dermatologists working with eczema or rosacea patients typically suggest sulfate-free alternatives, as even the milder SLES can exacerbate these conditions. For most patients with normal to combination skin, this cleanser provides an appropriate balance of cleansing efficacy and gentleness.
Guidance
Usage & Recommendations
How to Use
Wet face with lukewarm water. Squeeze a small amount (about the size of a nickel) into palms and work into a light lather. Massage gently over the face and neck in circular motions for 30-60 seconds, avoiding the eye area. Rinse thoroughly with lukewarm water and pat dry. Use morning and evening. For makeup removal, precede with an oil-based cleanser or cleansing balm as the first step in a double-cleanse routine.
Value Assessment
At $26 for 5 fl oz, this cleanser sits in the accessible-premium range — more expensive than drugstore options but well below luxury cleanser pricing. The value proposition rests on the conditioning oil blend and Kiehl's formulation heritage rather than exotic or trending ingredients. With a 3-4 month lifespan at twice-daily use, the per-month cost comes to approximately $7-9. The 2.5 oz size at $16 is useful for travel but offers worse per-ounce economics. For a brand with 170+ years of apothecary heritage, the pricing feels fair if not exceptional.
Who Should Buy
Anyone looking for a reliable, fragrance-free daily cleanser that won't disrupt their skin's moisture balance. It's particularly well-suited for combination skin types who want the satisfying feel of a foaming cleanser without the drying aftermath, and for those building a Kiehl's-centered routine alongside the Ultra Facial Cream.
Who Should Skip
Those with very sensitive, eczema-prone, or rosacea-affected skin should look for sulfate-free alternatives. Consumers who prioritize paraben-free formulas will also want to look elsewhere. And anyone expecting transformative skincare benefits from their cleanser — brightening, anti-aging, acne treatment — should direct those expectations toward their leave-on products instead.

Myth vs. Reality
Common Myths
Myth
Foaming cleansers always strip the skin and damage the moisture barrier.
Reality
This formula's inclusion of squalane, avocado oil, and apricot kernel oil specifically counteracts the stripping potential of the surfactant system. The oils deposit a thin conditioning layer during cleansing, so the foam does its job without taking moisture with it.
Myth
Parabens in skincare are dangerous and should always be avoided.
Reality
The methylparaben and propylparaben in this formula are used at regulatory-approved concentrations as preservatives. Decades of safety data support their use at these levels. The Cosmetic Ingredient Review panel and the European Commission's Scientific Committee on Consumer Safety have both affirmed their safety in cosmetic products at concentrations up to 0.4% for individual parabens.
FAQ
Frequently Asked Questions
Is Kiehl's Ultra Facial Cleanser good for sensitive skin?
It's formulated to be gentle enough for most skin types, and the tri-oil system (squalane, avocado, apricot kernel) helps prevent stripping. However, it contains sodium laureth sulfate as its primary surfactant, which can be irritating for very sensitive or eczema-prone skin. If you have reactive skin, the newer Ultra Facial Barrier-Hydrating Cleanser may be a better option.
Does Kiehl's Ultra Facial Cleanser remove makeup?
It removes light makeup, dirt, and excess oil effectively, but it's not designed to break down heavy foundation, waterproof mascara, or long-wear products. For thorough makeup removal, use it as the second step after an oil-based cleanser or balm in a double-cleanse routine.
Why does Kiehl's Ultra Facial Cleanser contain parabens?
Methylparaben and propylparaben serve as preservatives to prevent microbial contamination and extend shelf life. They're used at concentrations well within regulatory safety limits established by the Cosmetic Ingredient Review panel. While some consumers prefer paraben-free products, these ingredients have decades of safety data supporting their use in cosmetics.
Can I use Kiehl's Ultra Facial Cleanser with retinol?
Yes — its gentle, conditioning formula makes it a suitable cleanser to use in a retinol routine. The squalane and plant oils help maintain barrier integrity, which is important when using potentially irritating actives like retinol. Cleanse gently, pat dry, then wait a few minutes before applying retinol.
Is Kiehl's Ultra Facial Cleanser worth the price?
At $26 for 5 oz, it's priced higher than drugstore cleansers but delivers genuine conditioning benefits during the wash step thanks to its squalane and plant oil blend. The 5 oz tube lasts 3-4 months with twice-daily use, bringing the monthly cost to around $7-9. Whether that's worth it depends on how much you value a cleanser that actively protects your barrier while cleansing.
