Review

Full Review

Most thinking about cleansers is, sensibly, defensive. A good cleanser is judged by what it does not do: does not strip, does not leave skin tight, does not disrupt the barrier. The bar sits at 'do no harm,' because cleansing — the act of using surfactants to lift away oil — is inherently a little destructive, and most cleansers either clear that low bar or fail it. The Prequel Gleanser is interesting because it is built on a more ambitious premise: that a cleanser can do better than not-harm, that the rinse-off step can leave skin in a more hydrated state than it started. Whether you find that premise convincing depends on what is actually in the bottle, so it is worth a proper look.

The name itself is the first clue. 'Gleanser' fuses 'glycerin' and 'cleanser,' and it is no idle wordplay — glycerin is the first ingredient on the list, at a stated 50%. Half the formula. That is an extraordinary level of glycerin for a cleanser; most contain a token amount, if any. Glycerin is a humectant, drawing and binding water, and at 50% it fundamentally changes what the cleanser does to your skin. Rather than the surfactants stripping moisture out unopposed, the glycerin is simultaneously flooding the skin with water-binding capacity. The surfactants themselves — cocamidopropyl betaine and a cocoamphodiacetate — are mild, sulfate-free, the gentle end of the spectrum. The cleansing still happens, but it happens inside a bath of glycerin, and skin is left soft and conditioned instead of squeaky.

Beyond the glycerin sits the more novel, more interesting element: the aquaporin angle. Aquaporins are a genuine piece of skin biology — tiny protein channels embedded in skin-cell membranes, whose job is to shuttle water between cells and distribute hydration through the skin. The Gleanser includes glyceryl glucoside and a dihydroxypropyl arginine derivative, ingredients studied for supporting aquaporin expression and activity. This is a different idea from humectancy. A humectant adds water from outside; an aquaporin-supporting active aims to help the skin manage and move its own water internally. To be honest about the evidence, this is an emerging area — promising research rather than decades of proof — so it belongs on the label as a thoughtful, science-forward inclusion, not a guaranteed result. But it is a genuine corner of skin science, not marketing vapour, and it reflects the dermatologist-developed seriousness of the brand. There is also inulin, a prebiotic to support the skin microbiome — a sensible touch, since cleansing is exactly the step that disrupts the skin's surface ecosystem — plus aloe and oat for soothing.

Used at the sink, the Gleanser delivers on its premise. It is a light gel producing a soft, low, gentle lather — and here is the one expectation to set: if you equate a big foamy lather with cleanliness, this will feel modest. That is by design; aggressive foam means aggressive surfactants. It rinses clean, and the after-feel is the whole point — skin feels genuinely clean but soft, conditioned, comfortable, with none of the tightness. For sensitive, dry or reactive skin, that is exactly right; oily skin will find it comfortable too.

What also stands out, the longer you use it, is consistency. A cleanser is the step you repeat twice a day, every day, and a gentle one only proves its worth over weeks of not quietly eroding the barrier the way a harsher wash would. Skin that tends to feel tight and flaky by mid-morning after cleansing simply stops doing that. Combination skin gets clean without the oily zones being stripped into rebound shine. And the option to choose the salicylic or glycolic versions means a household can settle on one base it trusts and still tailor the formula to different faces. For the most-used, least-glamorous step in skincare, that reliability is the whole point.

Its limits are the ordinary boundaries of a gentle cleanser. It will not take off heavy makeup or sunscreen alone, so at night it works best as the second step of a double cleanse rather than a standalone wash. The plain version carries no exfoliating actives — though Prequel sensibly offers the same gentle base in salicylic acid and glycolic acid versions, so exfoliation is available without giving up the formula. And the aquaporin benefit, as noted, rests on emerging rather than settled evidence, so it is best treated as a bonus rather than the reason to buy.

At around sixteen dollars, value is good — a dermatologist-developed, fragrance-free, genuinely non-drying cleanser, fungal-acne safe, at an accessible price. To sum up: the Gleanser makes good on its slightly ambitious promise. It is not merely a cleanser that fails to harm your skin — it is one engineered, through an unusual quantity of glycerin and a genuinely interesting hydration-support angle, to leave your skin a little better than it found it. For anyone whose skin runs dry, sensitive or easily stripped, that is a genuinely worthwhile thing for the most basic step of a routine to do.

Evidence

Science & Expert Perspective

The Science

This cleanser is a well-constructed example of low-irritation, hydration-focused formulation. Its surfactants — cocamidopropyl betaine and disodium cocoamphodiacetate — are mild relative to anionic sulfate surfactants, and milder surfactant systems are linked to less stratum corneum and barrier disruption. The defining feature is the stated 50% glycerin; glycerin is one of the most extensively evidenced humectants, and at this level it substantially offsets the moisture loss inherent to cleansing, leaving skin measurably more comfortable.

The aquaporin component is the more novel element. Aquaporins, particularly aquaporin-3 in the skin, are membrane channel proteins that move water, and glycerol, between epidermal cells and are genuinely involved in skin hydration. Glyceryl glucoside has research support for upregulating aquaporin-3 expression, and dihydroxypropyl arginine is included for related hydration support. This is a legitimate, scientifically grounded area, though the clinical evidence for topical aquaporin-targeting in a rinse-off cleanser specifically is emerging rather than established. Inulin is a prebiotic with developing evidence for supporting the skin microbiome; aloe and oat add soothing properties.

The formulation is fragrance-free and free of sulfates and added alcohol — choices consistent with minimizing irritation. The realistic outcome is effective, genuinely non-drying everyday cleansing that leaves skin hydrated and comfortable; the high glycerin content is the well-evidenced workhorse, with the aquaporin-support actives a promising, science-forward addition. Its scope is cleansing — it carries no treatment actives and does not remove heavy makeup or sunscreen on its own.

Dermatologist Perspective

Dermatology consistently recommends gentle, non-stripping, sulfate-free cleansers, and a formula built on mild surfactants with a very high glycerin content aligns closely with that guidance — clinicians frequently note that the post-cleanse 'tight' feeling signals barrier disruption and that a cleanser should leave skin comfortable, which a heavily humectant formula supports. Aquaporin-3 is a genuine and recognized contributor to epidermal hydration, and ingredients studied for supporting it, such as glyceryl glucoside, are viewed with cautious interest, though dermatologists would note the evidence for aquaporin-targeting in topical products, particularly rinse-off ones, is still developing. Fragrance-free formulation is preferred for sensitive and reactive skin, and prebiotic and soothing botanical additions are regarded as low-risk and reasonable. Clinicians generally view the cleanser as the step where gentleness matters most, and would consider this a sound, low-irritation choice for most skin, including sensitive and dry skin. The standard guidance applies: cleanse twice daily with lukewarm water, double cleanse in the evening if wearing makeup or sunscreen, and follow with moisturizer and daily sunscreen.

Guidance

Usage & Recommendations

How to Use

Reach for it morning and evening. Work a small amount over damp skin, massage gently across the face, then rinse thoroughly with lukewarm water. In the evening, if you have worn makeup or sunscreen, treat it as the second step of a double cleanse, following an oil cleanser or cleansing balm that has lifted the makeup and SPF. Carry on with the rest of your routine afterward — serums, moisturizer, and sunscreen in the morning. Skip hot water, which is drying in its own right.

Value Assessment

At around $16, the Gleanser is good value — a dermatologist-developed, fragrance-free, genuinely non-drying cleanser at an accessible price, in keeping with Prequel's affordable positioning. With twice-daily use a bottle lasts roughly two to three months, and larger sizes are available for better per-use economy. Compared with gentle hydrating cleansers from mid-range and prestige brands, which often run $20 to $40, the pricing is competitive, and few match its 50% glycerin content. The variant system adds value too: the same gentle base is available with salicylic or glycolic acid, so a buyer can match the formula to their needs without trading away the non-drying quality. For a reliable, gentle everyday cleanser, the value is straightforwardly strong.

Who Should Buy

Anyone after a genuinely gentle, non-drying everyday cleanser is well served here — it suits sensitive, dry, normal and combination skin especially, works fine for oily skin, and makes an excellent second step in a double cleanse. It is a particularly sound choice for anyone whose skin feels tight or stripped after washing.

Who Should Skip

Anyone who wants a single cleanser to remove heavy makeup and sunscreen alone should pair it with an oil cleanser or choose a dedicated makeup remover. Those who want a cleanser with exfoliating actives should consider Prequel's salicylic or glycolic acid versions instead, and foam-lovers may find the gentle lather underwhelming.

Myth vs. Reality

Common Myths

Myth

A cleanser only needs to not strip the skin — it cannot actually hydrate.

Reality

Most cleansers are at best neutral and at worst stripping, because they rinse off. But a cleanser loaded with humectants — here 50% glycerin — and water-channel-supporting actives can leave the skin measurably more hydrated and comfortable than before. A cleanser can do more than simply not harm; this one is designed to.

Myth

Aquaporin skincare is just a fancy name for a moisturizer.

Reality

Aquaporins are real protein channels in skin cells that move water between them. Some ingredients, like glyceryl glucoside, are studied for supporting aquaporin activity — a different mechanism than a humectant pulling water from the air. It is a genuine, if still emerging, area of skin science, not just rebranding.

FAQ

Frequently Asked Questions

What is the Prequel Gleanser?

It is a non-drying gel cleanser built around a remarkable 50% glycerin — hence the name, a blend of 'glycerin' and 'cleanser.' Gentle sulfate-free surfactants clean the skin while the high glycerin, an aquaporin-supporting complex, a prebiotic and soothing botanicals leave it hydrated and comfortable rather than stripped.

What does the aquaporin-supporting complex do?

Aquaporins are protein channels in skin cells that move water between them. The Gleanser includes glyceryl glucoside and dihydroxypropyl arginine, studied for supporting aquaporin activity — a way of helping the skin manage its own internal water, distinct from a humectant simply drawing in moisture. It is a genuine but still-emerging area of skin science.

Is the Gleanser good for sensitive or dry skin?

Yes — it is well suited to it. The formula is fragrance-free, sulfate-free, exceptionally gentle, and packed with hydrating glycerin and soothing aloe and oat. It cleans without stripping, leaving skin soft and comfortable, which makes it one of the better cleansers for sensitive, dry and reactive skin.

Does the Gleanser remove makeup and sunscreen?

It cleanses light, everyday wear, but it is not designed to remove heavy makeup or sunscreen on its own. In the evening, use it as the second step of a double cleanse — after an oil cleanser or balm — for a thorough but gentle result.

What is the difference between the Gleanser versions?

Prequel offers the Gleanser in three versions on the same gentle, glycerin-rich base: the plain Gleanser, a Gleanser with salicylic acid for congestion-prone skin, and a Gleanser with glycolic acid for texture and tone. The plain version reviewed here is the gentlest, with no exfoliating actives.
