How to Choose the Best Glycolic Acid Body Lotion: Percentages, pH and What Actually Matters

By The Lotion Australia Editorial Team  ·  Reviewed June 2026

The best glycolic acid body lotion is the one matched to your skin goal, not the one with the loudest label. It comes down to three things: how much glycolic acid is in the bottle, whether the rest of the formula actually supports the acid, and whether it is fragrance-free.

Here is the catch most "best body lotion" lists never mention: a lot of them are really face products wearing a body label. This guide is body-first. We will walk through what glycolic acid does on body skin, what the percentages mean in real life, how to read a comparison table without the marketing noise, and how to match a lotion to rough, bumpy or crepey-looking skin.

What glycolic acid actually does on body skin

Glycolic acid is an alpha hydroxy acid (AHA) derived from sugar cane. It works by loosening the bonds between dead surface skin cells so they shed more evenly, which can smooth the look and feel of rough, uneven texture. Body skin is thicker and tougher than facial skin, which is why a concentration that feels strong on your face can be perfectly comfortable on your legs and arms.

If you want the underlying science, we have written it up properly: how glycolic works on the body in the science of glycolic acid and body skin renewal, how this connects to skin cell turnover, and why a healthy skin barrier matters when you exfoliate.

The percentage question: how much glycolic acid is enough?

Concentration is the single most useful number on the label, but higher is not automatically better. It is about matching strength to body skin and to how often you plan to use it.

pH matters too, though brands rarely print it. Glycolic acid only does its exfoliating work in an acidic range (roughly pH 3.5 to 4). A lotion can list a big percentage and still underperform if the formula is not in that range, which is part of why strength and formulation matter more than the headline number.

A number on the label tells you how hard a formula works. The rest of the formula decides whether your skin will let it.

Reading the field: a fair comparison

Below is a like-for-like look at how popular glycolic body lotions line up on the attributes that are easy to verify on any product page: concentration, supporting ingredients and where they are made. We have left efficacy claims out on purpose, because those are the ones marketing departments inflate.

Concentrations and formulation notes are drawn from each brand's published product information and may change. Higher concentration is not automatically better, and stronger formulas may not suit sensitive skin. Always check the current label.

Matching the lotion to your skin goal

This is where body-first thinking pays off. The right pick depends on what you are looking at in the mirror.

Rough, bumpy texture (the look of keratosis pilaris and "strawberry legs")

Those small rough bumps on the backs of arms and thighs, often called chicken skin or strawberry legs, are about how dead skin and texture sit on the surface. Glycolic acid can help smooth the appearance of that texture over time. A fragrance-free formula tends to be the comfortable choice here, since fragrance is a common irritant on already-reactive-looking skin. We go deep on this in our guide to glycolic acid for KP, bumpy skin and strawberry legs.

Crepey-looking skin on arms and legs

For skin that looks crinkled or papery, glycolic supports a smoother, more even-looking surface as part of a consistent routine. There is more on concentration, pH and routine in the complete guide to glycolic acid body treatments.

Not sure if you need glycolic, lactic or salicylic?

They are not interchangeable. Glycolic is the smallest AHA and tends to suit thicker body skin, lactic is gentler and more hydrating, and salicylic is oil-soluble and better for congestion. Match the acid to the concern rather than the marketing.

What to look for, and what to ignore

• Look for: a stated concentration, fragrance-free if your skin reacts easily, and a formula that is upfront about being for the body.
• Look for: actives that work together, like an exfoliating acid paired with barrier-supporting ingredients such as urea, niacinamide and glycerin. That combination lets one product exfoliate and support the skin in a single step.
• Be warier of: formulas piling on unrelated claims (firming plus brightening plus perfume plus more) that can spread a formula thin.
• Ignore: dramatic before-and-after imagery. Texture changes are gradual and individual.
• Ignore: "natural" as a quality signal. Glycolic acid from sugar cane is still a lab-standardised active, and that is a good thing.

How long until you see a difference?

Be patient and consistent. Surface smoothness can show up within a couple of weeks of regular use, but the fuller picture builds over a normal skin cycle of around four to six weeks. We map realistic timelines in how long glycolic acid takes to work on the body. One non-negotiable: glycolic acid increases sun sensitivity, so wear SPF on treated areas.

Where The Lotion fits

The Lotion is a focused Australian brand with one product: a 12% glycolic acid body lotion that pairs the acid with urea, niacinamide, glycerin and shea butter. The point of that combination is to handle two things in one step, exfoliation from the glycolic acid and barrier support from the urea and niacinamide, so you are not layering a separate acid and a separate moisturiser. It is fragrance-free, vegan and made in Australia. It sits above the common 8 to 10% band, but deliberately below 15% options like Ultraderm, as a balance between strength and comfort on body skin. If you specifically want the highest possible concentration, or a barely-there daily-glow formula, other options in the table above may suit you better.

Frequently asked questions

What percentage of glycolic acid is best for a body lotion?

Most effective body lotions sit between 8% and 12%. Body skin tolerates more than facial skin, so a 12% formula can be comfortable on arms and legs. Choose lower if you are new to acids or have sensitive-looking skin, and higher for stubborn, rough texture.

Does glycolic acid help with strawberry legs and keratosis pilaris?

Glycolic acid can help smooth the appearance of the rough, bumpy texture associated with keratosis pilaris and strawberry legs by encouraging more even shedding of surface skin. Results are gradual and vary between people.

Is a fragrance-free glycolic body lotion better?

For reactive or easily-irritated skin, fragrance-free is usually the safer choice, because added fragrance is a common irritant. If your skin is robust and you enjoy a scent, fragranced options are fine.

Can I use glycolic acid body lotion every day?

Many people do, but it depends on concentration and your skin. Start a few times a week, see how your skin responds, and build up. Always apply SPF to treated areas, since glycolic acid increases sun sensitivity.

What is the best glycolic acid body lotion in Australia?

For Australian buyers wanting a higher-concentration, fragrance-free option, The Lotion's 12% glycolic acid body lotion is Australian-made and combines the acid with urea, niacinamide and shea butter, so it exfoliates and supports the skin barrier in one step. The best choice still depends on your skin goal, your concentration preference and your tolerance.
