NeoStrata Foaming Glycolic Wash Review: 18% Glycolic Acid Cleanser Tested
The Verdict
Foaming Glycolic Wash is a genuine step-up product, not a beginner cleanser, and NeoStrata is upfront about that — sensitive and reactive skin are explicitly excluded, and the 18% Glycolic Acid concentration is high even by the brand's own standards. For someone who already uses AHA products comfortably and wants a stronger resurfacing cleanse, it does a focused job. If you're newer to acids, it's worth working up through NeoStrata's gentler options first rather than starting here.
NeoStrata Foaming Glycolic Wash | AHA Cleanser | 125ml
£23.00
NeoStrata Foaming Glycolic Wash is a rinse-off, self-foaming cleanser built around 18% Glycolic Acid and 2% Lactobionic Acid — the strongest facial wash in NeoStrata's range. It's designed for experienced AHA users with dry, normal or oily skin, and the brand states it is not recommended for sensitive or reactive skin. As a cleanser rather than a leave-on treatment, contact time is short, but this is still a step-up formula, not a starting point.
What is NeoStrata Foaming Glycolic Wash?
Foaming Glycolic Wash sits within NeoStrata's Resurface collection, the brand's higher-strength glycolic acid line built for skin that already tolerates regular chemical exfoliation. The formula combines 18% Glycolic Acid with 2% Lactobionic Acid in a pH-balanced, soap-free base that turns into a light foam on application. NeoStrata positions it as a cleanser that exfoliates whilst it washes, rather than a treatment to leave on the skin.
Because it's rinsed off within a minute or two of application, the skin's exposure to the acid is much shorter than with a leave-on product at the same strength — one reason NeoStrata can use a higher percentage here than in most of its leave-on treatments. That doesn't make it a gentle formula, though: the brand is explicit that this wash is not recommended for sensitive or reactive skin, and it's intended for people who already use AHA products regularly.

Key ingredients
Glycolic Acid (18%)
Glycolic acid is an alpha hydroxy acid (AHA) derived from sugar cane, and it has the smallest molecular size of the commonly used AHAs, which is generally understood to make it more effective at penetrating the skin's surface. At 18%, this is a high concentration for a cosmetic AHA product — well above what most over-the-counter leave-on treatments use — which is why NeoStrata reserves it for a rinse-off format and flags it as unsuitable for sensitive skin.
Lactobionic Acid (2%)
Lactobionic acid is a polyhydroxy acid (PHA) with a larger molecular structure than glycolic acid, which means it doesn't penetrate as deeply and is generally considered gentler. It's also a humectant, helping the formula hold moisture at the skin's surface. Pairing it with glycolic acid here is a common approach in NeoStrata's range — using a PHA alongside a stronger AHA to help offset some of the drying effect of high-strength glycolic acid.
Texture and how it feels
The formula starts as a lightweight, soap-free liquid and builds into a foam once worked into damp skin. NeoStrata's stated aim is a cleanser that removes make-up, oil and impurities whilst exfoliating in the same step, rather than a plain cleanser you'd follow with a separate acid treatment. It rinses away cleanly without the tight, stripped feeling associated with traditional soap-based washes — a common formulation goal for pH-balanced, soap-free cleansers generally, not a claim specific to this product.
Who is it suitable for?
- Experienced AHA users with dry, normal or oily skin wanting a stronger exfoliating cleanser than a standard wash
- Anyone looking to prep skin ahead of other actives, given its role as a resurfacing first step
- Those who've used gentler NeoStrata glycolic products and want to progress to a higher-strength formula
Who should skip it?
- Sensitive or reactive skin — the brand explicitly excludes this skin type from this product
- Anyone new to chemical exfoliation — start with a lower-strength AHA or PHA product and build tolerance first
- Anyone already using a strong AHA or retinoid step in the same routine, without easing the two together gradually
Foaming Glycolic Wash vs Glycolic Renewal Smoothing Lotion
NeoStrata sells two glycolic acid products that are easy to confuse: this wash, and the Glycolic Renewal Smoothing Lotion. They are not interchangeable. Foaming Glycolic Wash is a rinse-off cleanser at 18% Glycolic Acid, with the acid's contact time limited to the wash itself. The Smoothing Lotion is a leave-on product, formulated at a lower AHA percentage, designed to stay on the skin. Using both in the same routine without care can mean layering more acid exposure than intended — see our full Foaming Glycolic Wash vs Glycolic Renewal Smoothing Lotion comparison before combining them.
How to use NeoStrata Foaming Glycolic Wash
- Wet the face with lukewarm water, then apply a small amount and massage in to build the foam.
- Rinse thoroughly. Because this is a cleanser rather than a leave-on treatment, there's no need to leave it on the skin beyond normal washing time.
- Patch test before first full use, and introduce it gradually into your routine rather than replacing your usual cleanser outright — this is standard advice for any new high-strength AHA product, not a brand-specific instruction.
- Avoid combining with another strong AHA, BHA or retinoid step in the same session until you know how your skin responds; NeoStrata's own AHA cleansers, like the gentler Skin Active Exfoliating Wash, are worth considering if you want to alternate strength through the week.
- Oily or blemish-prone skin often follows an AHA cleanse with a toning step — NeoStrata's Clarify Oily Skin Solution Toner is formulated for that skin type.

Frequently asked questions
Is NeoStrata Foaming Glycolic Wash suitable for sensitive skin?
No. NeoStrata states this product is not recommended for sensitive or reactive skin. If you have a diagnosed sensitive-skin condition, our NeoStrata glycolic acid products ranked guide points to gentler starting options, and our team can talk you through alternatives.
How much glycolic acid is in NeoStrata Foaming Glycolic Wash?
The formula contains 18% Glycolic Acid alongside 2% Lactobionic Acid, making it the highest-strength facial wash in NeoStrata's range.
How does NeoStrata Foaming Glycolic Wash differ from a regular cleanser?
Most standard cleansers are formulated purely to remove make-up, oil and dirt. This wash adds a high-strength AHA to that step, aiming to exfoliate the skin's surface at the same time as cleansing — which is why NeoStrata restricts its recommended use to experienced AHA users rather than positioning it as an everyday, universal cleanser.
Can I use NeoStrata Foaming Glycolic Wash every day?
NeoStrata doesn't publish a specific frequency recommendation for this product on its packaging or product page, so we can't state an official usage schedule here. Given the strength of the formula, we'd suggest starting less often than your normal cleanse and building up gradually while watching how your skin responds, or asking our team for guidance tailored to your routine.
Does NeoStrata Foaming Glycolic Wash sting?
A mild tingling sensation is common with high-strength AHA cleansers, even rinse-off ones, particularly on first use. Persistent stinging, redness or discomfort isn't expected and is a sign to stop use and get in touch with our team. Patch testing before your first full application is the best way to check how your skin reacts.
What should I use after NeoStrata Foaming Glycolic Wash?
Because it's a cleansing step, what follows depends on the rest of your routine. Oily or blemish-prone skin often follows with a toning step, such as NeoStrata's Clarify Oily Skin Solution Toner, before moving on to serum and moisturiser. If you're pairing this wash with another active treatment step, introduce them gradually rather than all at once.
