NeoStrata Ranges Explained: Glycolic, PHA and the Rest

The short version: NeoStrata product names tell you very little about which range a product belongs to, and the range is the thing that matters. Two of them do the actual exfoliating work, and they sit at opposite ends of a tolerance scale. Resurface is built on glycolic acid and other alpha hydroxy acids. Bionic is built on polyhydroxy acids. The rest of the collections are jobs rather than strength tiers: cleansing, tone, eyes, neck, sun protection. Once you know which of the two spines you belong on, the rest of the range assembles itself around it.

This is a map of the brand, not a chemistry lesson. If the question you're really asking is how hydroxy acids work, which family suits your skin, how sun sensitivity fits in and what over-exfoliating looks like, our guide to AHAs and BHAs: what they do, how they differ and which one your skin needs answers all of that properly, and there's no point us writing it twice. Come back here when you want to know what actually goes in the basket.

Why does the NeoStrata range split in two?

The split isn't marketing. It's the brand's own research history showing up in the product line.

Alpha hydroxy acids entered dermatology through the work of Dr Eugene Van Scott, a dermatologist, and Dr Ruey Yu, a chemist, whose landmark paper on controlling keratinisation with alpha hydroxy acids ran in Archives of Dermatology in 1974. They described how these acids loosen the bonds between surface skin cells, which is why skin sheds more readily afterwards and looks smoother. Almost every glycolic product on the market sits downstream of that paper, and the company the pair went on to found is NeoStrata.

What really shaped the range, though, was the follow-up. Classical AHAs have a real limitation, in that a meaningful share of people simply can't use them comfortably, so the same team went on to develop polyhydroxy acids, gluconolactone and lactobionic acid, as a second family meant to give a similar result more slowly and with less sting. That second family became Bionic. NeoStrata is unusual in carrying both generations of its own research side by side, under two names, rather than quietly replacing one with the other. Other brands formulate excellent glycolic acid and excellent PHAs too. NeoStrata just happens to label the division openly, which makes it an easy range to navigate once you know the code.

Resurface: the AHA spine

This is where the glycolic acid lives, and where the strongest products in the range sit. Browse it as the NeoStrata Resurface collection.

• Glycolic Renewal Smoothing Lotion. A 10% AHA blend of glycolic and citric acid. NeoStrata explicitly flags it as unsuitable for sensitive or reactive skin, which is a useful bit of honesty on an entry-level product.
• Smooth Surface Daily Peel. 10% glycolic acid in a two-step format, so the exposure is short and controlled rather than left on all night.
• Resurface High Potency Cream. The top of the range, pairing 18% glycolic acid with lactobionic acid and vitamin E. That's a deliberate hybrid rather than a straight step up, and again it isn't intended for sensitive skin.
• Foaming Glycolic Wash. Filed under cleansers rather than Resurface, but it belongs to this family. It's the gentlest possible way to meet glycolic acid, because a cleanser is on the skin for seconds rather than hours, which makes it a sensible first purchase if you're unsure whether acids suit you at all.

The number on the front isn't directly comparable between products, by the way. A "10% AHA blend" is two acids sharing that 10%, and the pH of the formula changes how much of the acid is present in its active form. Format matters at least as much. The same acid in a two-minute peel and in an overnight cream are two different experiences.

Bionic: the PHA spine

Same intent, gentler delivery. The polyhydroxy acids here, gluconolactone and lactobionic acid, are much larger molecules than glycolic acid, so they work over a longer window, and they hold water at the surface while they do it. Browse the NeoStrata Bionic collection.

• Bionic Face Serum. Built on 10% lactobionic acid, positioned for dry, sensitive and reactive skin.
• Bionic Lotion. A 15% PHA blend of 12% gluconolactone and 3% lactobionic acid, doubling as a moisturiser for face, hands and body. For a minimal routine, that's an efficient way to get exfoliation and moisturisation out of one bottle.
• PHA Renewal Pads. The low-effort option if you'd rather swipe than layer.

Bionic is also the part of the range that suits post-procedure care, and the situation where you're already using a retinoid and don't want a second source of irritation on the same face.

You may well want one from each

Here's the combination most people never think of: a Bionic product as the everyday base, with a Resurface product two or three evenings a week. The PHA keeps skin comfortable on the nights the glycolic is off, which is exactly where glycolic-only routines tend to come unstuck. The High Potency Cream is that same logic squeezed into a single jar.

The supporting ranges

These aren't weaker or stronger versions of the two above. They're different jobs, and you pick from them whichever spine you're on.

• Enlighten is the tone range, aimed at the appearance of dark marks and uneven colour rather than at texture. It layers with either spine.
• Eye care covers eye treatments formulated for the thinner skin around the eye, where a leave-on face acid is usually the wrong tool. There's a separate neck range for the same reason: the neck and décolletage get skipped in most routines and behave differently from the face.
• Sun protection means a daily broad-spectrum SPF, which helps prevent UV damage and is the non-negotiable companion to any exfoliating routine. Exfoliating for tone without daily protection undoes the work you started it for.
• Cleansers are mostly gentle, with the glycolic wash above as the exception. A cleanser is the one place in the range where you can borrow from the other spine without much consequence.

How do you build a routine from the NeoStrata ranges?

A workable NeoStrata skeleton, whichever spine you're on:

1. Morning. Cleanser, any targeted serum you use, moisturiser, SPF. Keep the exfoliating step out of the morning while you're still building tolerance.
2. Evening, exfoliating nights. Cleanser, then your Resurface or Bionic step on dry skin, then moisturiser. One exfoliating product, not three.
3. Evening, other nights. Cleanser, moisturiser, and whatever else your routine already contains.

The most common mistake with a range this deep is stacking. A glycolic wash, a glycolic lotion and a retinoid on the same evening is three exfoliating steps wearing different labels. Our ingredient layering guide sets out an order that holds up.

Where does NeoStrata fit alongside what you already own?

You don't need to be single-brand about this, and the range isn't built to force it. NeoStrata's practical advantage is that its exfoliating tiers are explicitly labelled, so stepping up or stepping across is a decision you can make deliberately rather than by trial and error. If your routine is already built around another professional brand's retinoid or vitamin C, the sensible move is usually to slot one NeoStrata exfoliating product into it rather than rebuild everything at once.

Equally, if acids have never suited you at any concentration or in any format, the honest answer may be that exfoliation isn't the missing piece of your routine. That's a legitimate conclusion, not a failure to find the right product.

Where to start

If you're still deciding between the two spines, start on the gentler one. A PHA that turns out to have been unnecessary costs you a few weeks. A glycolic acid that turns out to have been too much costs you a compromised skin surface and a month of undoing it.
