The full review.
The BHA toner is the castor oil of skincare: effective, respected, and as pleasant as a dental cleaning. Most 2% salicylic acid toners use a scorched-earth approach: they strip pores, dry the surface, and leave the moisturizer to fix the damage. Anua asks a different question: what if the toner itself performs the repair?
The formula acts as a peace treaty between exfoliation and hydration. Salicylic acid is fourth in the INCI list at a full 2%—the maximum over-the-counter concentration—so this is not a watered-down “gentle” toner. The gentleness comes from the supporting ingredients, not dilution. Ceramide NP with hydrogenated lecithin provides barrier-repair lipids. Eight forms of hyaluronic acid create a hydration safety net. Centella asiatica soothes exfoliation-triggered inflammation. Tea tree extract adds antibacterial coverage. It is an exfoliating toner in full protective gear.
The dual BHA strategy matters. Alongside pharmaceutical-grade salicylic acid, Anua includes Salix Alba (willow) bark extract—the natural precursor to salicylic acid. Willow bark converts to salicylic acid via enzymatic processes on the skin, providing a slower, gentler secondary exfoliation that extends the active’s working time without increasing peak irritation. This subtle choice helps the toner stay effective without being aggressive.
On the skin, this toner is uncomplicated. Pump out a few doses—the packaging is functional and hygienic—and pat it onto clean, dry skin. The texture is watery with slight viscosity and absorbs within seconds. The main complaint is tackiness. A film remains. It is not permanent and mostly disappears once you layer your next product, but it is there. If you require a clean, matte finish between steps, it will bother you.
The scent is divisive. There is no added fragrance, but salicylic acid and tea tree extract smell medicinal. Some users describe it as faintly like burning rubber, which is accurate and shows how subjective scent is. It dissipates quickly, but sensitive noses should be aware.
This toner delivers on its core promise. Within two weeks of consistent evening use, blackheads become less visible and skin texture smooths out. Pore congestion clears gradually, consistent with a well-buffered 2% BHA approach. This toner will not provide a dramatic overnight transformation. It keeps pores consistently clear if used regularly.
It falls short on stubborn, deep-seated congestion. Users used to the immediate power of aggressive BHA products may find this too mild. The gentle formulation that helps BHA beginners also limits its ceiling for experienced users with severe congestion. It is an excellent first BHA and an excellent maintenance BHA, but it may not conquer your worst breakout.
Anua launched this toner in late 2023 as the exfoliating counterpart to their Heartleaf 77% Soothing Toner. It was clinically tested at the Korea Institute of Dermatological Sciences and gained a following on TikTok as “the BHA that doesn’t hurt.” Over a thousand reviews later, the consensus is consistent: gentle, effective for mild to moderate congestion, and slightly tacky.
At twenty dollars for 150ml, the value is solid. You get a premium-ingredient BHA toner with ceramide, multi-weight HA, centella, and tea tree—ingredients many competitors omit to cut costs. The pump dispenser is a practical upgrade over standard splash bottles. Three to four months of nightly use from one bottle makes the per-use cost negligible.
For blackhead-prone users punished by every BHA product, this toner is different: exfoliation that respects the skin. The tackiness and scent are real compromises, but they are the price of a formula that prioritizes your barrier alongside your pores.

The science.
The Science
Salicylic acid at 2% is the most studied OTC concentration for acne and pore management. A 2015 review in Clinical, Cosmetic and Investigational Dermatology confirmed 2% salicylic acid reduces comedone count and inflammatory lesions more than a vehicle alone, with a favorable side effect profile. Salicylic acid is oil-soluble—unlike most common hydroxy acids—so it penetrates the sebum inside pores to dissolve the lipid matrix holding comedonal plugs together.
This toner uses a dual BHA approach, combining pharmaceutical salicylic acid with Salix Alba (willow) bark extract. Willow bark contains salicin, which esterase activity on the skin surface converts to salicylic acid. Research in Phytotherapy Research shows willow bark extracts provide anti-inflammatory and antimicrobial activity beyond salicin alone, likely due to additional phenolic compounds.
Melaleuca alternifolia (tea tree) extract has documented antibacterial activity against Cutibacterium acnes. A 1990 study in the Medical Journal of Australia compared 5% tea tree oil to 5% benzoyl peroxide for acne and found comparable efficacy in reducing inflamed and non-inflamed lesions, but with fewer side effects. This toner uses tea tree extract instead of concentrated oil, but the antimicrobial effect complements the salicylic acid pore-clearing action.
Ceramide NP with hydrogenated lecithin addresses a common BHA problem: barrier compromise from repeated exfoliation. The lecithin-ceramide delivery system mimics the stratum corneum lipid architecture, replenishing barrier lipids while removing dead cells. This dual-action approach matches research in the Journal of Investigative Dermatology showing that ceramide-supplemented exfoliant formulations maintain lower transepidermal water loss (TEWL) values than conventional exfoliants.

Dermatologist Perspective
Dermatologists often recommend salicylic acid as a first-line topical treatment for blackheads and comedonal acne. Board-certified dermatologists say 2% is the optimal OTC concentration—effective for mild to moderate acne and tolerable for most skin types. Adding ceramide NP and hyaluronic acid to this toner is a clinically sound way to exfoliate; dermatologists emphasize that maintaining barrier integrity during treatment improves tolerance and long-term outcomes. Dermatologists commonly recommend this formulation for patients who find simpler BHA products irritating, or as a maintenance treatment alongside prescription acne regimens.
Where it fits in your routine.
Cleanse and dry your face, then pump 2-3 pumps of toner onto your palm or a cotton pad. Pat or swipe it gently across the face, targeting congested areas like the nose, chin, and forehead. Avoid the immediate eye area. Wait 1-2 minutes before your next skincare step. Use 2-3 times per week, then increase to nightly use as tolerated. Use in the PM routine only. Always apply broad-spectrum sunscreen the next morning because BHA increases photosensitivity.
At $20 for 150ml, this toner is a good value in the BHA category. The ingredient list — ceramide NP, eight hyaluronic acid forms, centella extract, tea tree extract, and vitamin E — exceeds what most BHA toners offer at this price. One bottle lasts 3-4 months with nightly use, making the per-use cost less than $0.20. Only one size exists, so there is no bulk discount. For an emerging brand, clinical testing from the Korea Institute of Dermatological Sciences adds credibility to its limited long-term track record.
This works for oily or combination skin types dealing with blackheads, clogged pores, or mild acne. It provides BHA exfoliation without a harsh stripping sensation. It suits BHA beginners and people who find other salicylic acid products too irritating.
People with dry or very sensitive skin who cannot tolerate gentle BHA exfoliation. It is also not ideal for users with severe or cystic acne needing prescription-strength treatment, or anyone who dislikes the tacky finish and medicinal scent.
Product details.
Thin, watery liquid, slightly thicker than water. It absorbs fast but leaves a tacky film on the skin surface.
It has no added fragrance, but a faint medicinal scent with tea tree undertones. Some users find it slightly unpleasant, which is common for salicylic acid products.
Anua uses a minimalist blue-navy color scheme on this sleek 150ml plastic bottle. The hygienic pump dispenser prevents contamination and allows precise dispensing.
The toner applies like water with slight viscosity on first use. Mild tingling often occurs during the first few applications, especially near active breakouts; this is normal and usually stops within a minute. It feels slightly tacky after absorption. Most users will not experience purging at this concentration, though some may have a 1-2 week adjustment period.

The backstory.
Anua developed this toner as the exfoliating companion to their best-selling Heartleaf 77% Soothing Toner, targeting users who wanted pore-clearing benefits without the harshness of traditional BHA products. Launched in 2023 and clinically tested at the Korea Institute of Dermatological Sciences, it quickly gained traction on TikTok as the gentler K-beauty alternative to Western BHA toners.
About Anua
Emerging Brand (2–5 years)Anua launched in 2020 as a South Korean skincare brand. It built its reputation with viral products like the Heartleaf Pore Control Cleansing Oil. The brand now offers active-focused exfoliants and treatments. Anua uses well-studied ingredients and has clinical testing from the Korea Institute of Dermatological Sciences, but its track record is shorter than established K-beauty brands.
Common myths.
BHA toners sting when they work — if you feel nothing, they are not working.
Stinging means irritation, not efficacy. The 2% salicylic acid in this toner dissolves oil-based plugs inside pores whether you feel a sensation or not. This gentle formulation lacks a harsh sting by design.
Wait 20-30 minutes after applying a BHA toner before you layer other products.
Early acid toner advice suggested long wait times, but current dermatological consensus says 1-2 minutes is enough for the BHA to start working. The slightly acidic pH of later products won't significantly neutralize the BHA.
FAQ.
Is the Anua BHA 2% Toner gentle enough for sensitive skin?
This toner is gentler than many 2% BHA products because it uses centella asiatica, ceramide NP, and a multi-weight hyaluronic acid complex. Still, 2% salicylic acid is an active exfoliant. Use it every other night and watch for irritation — the formula works better for sensitive skin than most BHA toners, but individual tolerance varies.
Does the Anua BHA Toner actually work for blackheads?
Yes — the 2% salicylic acid is oil-soluble. This allows it to penetrate pores and dissolve sebum plugs that cause blackheads. Users report fewer blackheads within 2-4 weeks of regular use. The willow bark extract adds a second BHA source for sustained pore-clearing.
Can I use the Anua BHA Toner with retinol?
Yes, but not on the same night. Alternate the BHA toner and your retinol product to prevent over-exfoliation. Use a hydrating serum and moisturizer after the BHA toner. The ceramide NP and hyaluronic acids in this toner buffer the combined effects of both actives when used on alternating nights.
Why does the Anua BHA Toner leave a sticky feeling?
The slight tackiness comes from the hydrating ingredients — specifically the multi-weight hyaluronic acids and the botanical extracts. This film helps subsequent products absorb better. The tackiness disappears once you apply your next skincare step.
Is 2% BHA strong enough to clear acne?
2% is the maximum OTC concentration for salicylic acid. It works for mild to moderate acne, blackheads, and pore congestion. Severe or cystic acne may require a dermatologist-prescribed treatment. This toner works best to prevent and maintain clear pores.
How often should I use the Anua BHA 2% Toner?
Use 2-3 times per week, then increase to nightly use as skin tolerance builds. Most users apply it every night or every other night. Do not use it in both the AM and PM; once daily in the PM routine works. Always use sunscreen the next morning.
Is the Anua BHA Toner safe during pregnancy?
ACOG guidelines state topical salicylic acid at 2% or less is generally safe during pregnancy. This toner stays within that safe range. Anua recommends patch testing during pregnancy because hormones change the skin. Consult your healthcare provider for personalized advice.
