The full review.
The double standard in skincare is real: we’ll spend twenty minutes layering acids, peptides, and ceramides on our face, then wash our body with something that’s basically perfumed detergent. Naturium’s The Smoother Glycolic Acid Exfoliating Body Wash exists to close that gap, bringing facial-skincare-grade formulation thinking to a product category that has been coasting on fragrance and suds for decades.
The headline active is 5% glycolic acid — the same concentration found in many face-specific exfoliating products, now deployed against the thicker, tougher stratum corneum of the body. Glycolic acid is the smallest AHA molecule, which gives it the deepest penetration and most aggressive exfoliation of the alpha-hydroxy acid family. On body skin, where dead cell buildup is heavier and turnover slower than on the face, that penetration depth is exactly what’s needed.
But Naturium didn’t stop at glycolic acid. The formula layers in four additional fruit acids — lactic, malic, tartaric, and pyruvic — creating a five-acid exfoliation system that targets the skin at multiple depths and through multiple mechanisms. Lactic acid adds humectant properties alongside its exfoliation, preventing the stripped feeling that glycolic alone can cause. Malic acid contributes mild exfoliation with good tolerability. Tartaric acid enhances the pH environment for the other acids. Pyruvic acid brings skin-brightening properties particularly relevant for dark spots on the body. Together, they create the most comprehensive acid profile in the body wash category.
The keratosis pilaris community discovered this product early and has been enthusiastic. KP — the rough, bumpy ‘chicken skin’ texture on upper arms, thighs, and sometimes cheeks — results from keratin protein clogging hair follicles. Glycolic acid is one of the most effective treatments because it dissolves keratin plugs directly. User reports of significant KP improvement within two to three weeks are consistent across hundreds of reviews, and this specific use case has driven much of the product’s word-of-mouth growth.
Body acne responds well too. The combination of surface-level AHA exfoliation and the overall smoothing effect helps prevent the dead cell and sebum buildup that creates body breakouts. Users dealing with back acne, chest acne, and ingrown hairs report noticeable improvement, particularly when combined with a body moisturizer containing additional AHA or urea.
The surfactant system deserves recognition. Rather than the sodium laureth sulfate that dominates mainstream body washes, Naturium uses sodium cocoyl isethionate and sodium methyl cocoyl taurate — gentle, sulfate-free cleansing agents derived from coconut. They clean effectively but produce less foam, which may disappoint users who equate lather with cleanliness. The trade-off is significantly less irritation, particularly important in a formula already containing five acids.
Fragrance-free in a body wash is genuinely unusual and worth celebrating. The vast majority of body washes — including many that market themselves as ‘sensitive skin’ options — contain parfum as a standard ingredient. Naturium’s decision to omit it entirely means the exfoliating acids can work without the additional irritation risk that fragrance compounds introduce. For the target audience — people with reactive body skin conditions like KP, eczema-adjacent texture issues, and body acne — this matters.
Chondrus crispus (red algae) extract provides a conditioning counterpoint to the acids, forming a hydrating film on the skin that prevents the stripped, tight sensation common after acid-based cleansing. Glycerin and sodium PCA add humectant support. The result is a body wash that exfoliates aggressively without leaving your skin feeling punished.
The value is exceptional. At $16.99 for 16.9 fluid ounces, this costs roughly the same as many basic drugstore body washes while delivering clinical-grade acid exfoliation. A bottle lasts two to three months with daily use. The per-ounce cost ($1.00) undercuts every comparable acid body wash on the market.
Usage is straightforward: apply to damp skin, let the lather sit for one to two minutes on target areas, rinse. The brief contact time limits acid exposure, making the 5% concentration gentler in practice than it sounds on paper. Most users tolerate daily use after a one-to-two-week adjustment period, during which every-other-day application is recommended.
The ingredient list is mercifully short — 24 ingredients total, most of which are functional necessities (surfactants, pH adjusters, preservatives). There’s no filler, no marketing ingredients, no ‘0.01% of exotic extract’ designed to look good on the label. Every ingredient serves a purpose. The polyquaternium conditioning agents help the formula rinse clean while leaving skin conditioned. Sodium lactate (the sodium salt of lactic acid) provides additional exfoliating support and acts as a natural moisturizing factor component.
For anyone who has spent years hiding bumpy arms under long sleeves, dealing with persistent back acne, or wondering why drugstore body washes never seem to do anything meaningful — this is the body wash that actually works. It’s not glamorous. It doesn’t smell like a tropical vacation. It’s a clinical tool in a squeeze bottle, and it does its job better than almost anything else at any price.

The science.
The Science
Clinical settings show 5% glycolic acid works well for body skin exfoliation. As the smallest AHA (molecular weight 76 Da), glycolic acid penetrates the stratum corneum deepest, which is thicker on the body than on the face. A 2001 study in Dermatologic Surgery confirmed glycolic acid reduces stratum corneum thickness and improves skin texture in a dose-dependent manner.
For keratosis pilaris, a Journal of the European Academy of Dermatology and Venereology study showed AHA-based topical treatments reduce perifollicular keratotic papules by dissolving excess keratin protein. The wash-off format matters—leave-on AHA products exfoliate longer, but the daily application of this body wash provides consistent, repeated exposure.
The multi-acid approach uses overlapping mechanisms. Lactic acid (MW 90 Da) has a larger molecular size, so it offers gentler surface exfoliation and humectant properties. Pyruvic acid exfoliates and brightens skin by inhibiting melanogenesis. This combination creates a 'staircase' of penetration depths, which provides more uniform exfoliation than a single acid.
Sodium cocoyl isethionate is the primary surfactant. It is a mild synthetic detergent with lower irritation potential than SLS. Research in the International Journal of Cosmetic Science confirms it works with compromised or reactive skin.
Dermatologist Perspective
Board-certified dermatologists often recommend glycolic acid as a first-line treatment for keratosis pilaris and body texture. Dermatologists say the 5% concentration in a wash-off format exfoliates the body effectively while remaining well-tolerated. The sulfate-free surfactant system is a plus, because traditional sulfates can increase dryness and irritation alongside exfoliating acids. Dermatologists advise using a ceramide or urea-based moisturizer after this body wash to support barrier recovery, and starting with use every other day before moving to daily use.
Where it fits in your routine.
Apply to damp skin in the shower. Massage into target areas (arms, legs, back, chest) and let the lather sit for 1-2 minutes before rinsing. Use every-other-day for the first 1-2 weeks, then increase to daily as tolerated. Always follow with body moisturizer. Non-sensitive skin can use it as a facial cleanser 2-3x/week.
At $16.99 for 16.9 oz ($1.00/oz), this acid body wash offers the best value. Alpha Skincare, First Aid Beauty, and prescription-adjacent brands charge $12-25 for 6-12 oz — two to four times the per-ounce cost. The clean formulation (sulfate-free, fragrance-free, vegan) provides value most body care products at this price point lack. A 2-3 month supply for under $17 makes consistent body exfoliation affordable.
Use this for keratosis pilaris, bumpy body texture, body acne, ingrown hairs, or dull body skin. It provides clinical-grade body exfoliation without fragrance or sulfates at an accessible price.
Use this for very sensitive or eczema-compromised body skin, active skin wounds, or sunburn. It suits those who prefer thick-lathering body washes. Patch test a small area if you have a history of AHA sensitivity.

The backstory.
Body care has long been an afterthought in the clinical skincare world — the same brands that formulate sophisticated facial products often phone in their body lines with basic surfactants and fragrance. Naturium's The Smoother applied facial-skincare-grade formulation thinking to the body wash category, bringing clinically relevant acid concentrations and a clean ingredient philosophy to a product segment that badly needed it.

Common myths.
Body washes with acids are too harsh for daily use
The wash-off format acts as a safety mechanism; 1-2 minutes of contact time limits acid exposure. 5% glycolic acid in a rinse-off product is gentler than a 5% leave-on facial treatment. Most users tolerate daily use well after an initial adjustment period.
Over-the-counter products do not treat Keratosis pilaris
KP results from keratin plugging hair follicles. Glycolic acid is a top OTC treatment; it dissolves keratin plugs and smooths bumpy texture. User reviews show consistent use of this body wash improves KP.
FAQ.
Does Naturium The Smoother body wash help with keratosis pilaris?
Yes — this is a top OTC product for KP. The 5% glycolic acid dissolves the keratin plugs that cause bumpy texture, and lactic acid adds exfoliation and hydration. Most users see improvement within 2-3 weeks of consistent use.
Can I use Naturium The Smoother on my face?
Naturium says this works as a facial cleanser. But at 5% glycolic acid plus fruit acids, it is too intense for sensitive facial skin. Use it on the face 2-3 times per week and follow with moisturizer and sunscreen.
Why doesn't this body wash lather much?
The formula uses sodium cocoyl isethionate and sodium methyl cocoyl taurate. These gentle, sulfate-free surfactants clean well but produce less foam than traditional SLS/SLES. Less lather means less irritation, not less cleansing.
Should I use a moisturizer after this body wash?
Yes — always use moisturizer after an acid body wash. Glycolic acid increases cell turnover and temporarily disrupts the skin barrier. A ceramide or urea-based body lotion locks in moisture and helps the barrier recover. For KP specifically, a body lotion with AHA provides more exfoliation.
Is Naturium The Smoother safe during pregnancy?
Glycolic acid in body care products is generally low-risk during pregnancy, though healthcare providers disagree. The 5% concentration in a wash-off format has minimal systemic absorption. Ask your OB-GYN for personalized guidance.
