Where to buy COSRX BHA Blackhead Liquid in Canada

What the prices tell you

Our October 2026 check found 3 retailers with the 100 ml BHA Blackhead Power Liquid in stock. The table above lists them from cheapest to most expensive, each with the date we checked.

• Lowest: Stylevana at C$16.99 (C$16.99 per 100 ml).
• Highest: Chuusi at C$26.00 (C$26.00 per 100 ml), which is 53% above the lowest.
• Cheapest from a Canadian warehouse: Kiokii at C$25.99.
• Out of stock when we checked: KBeauty Mart (C$21.99) and Lakinza (C$24.17).

What shipping looks like at each store

A shelf price isn’t the price you pay. These are the shipping terms we recorded for the stores in the table; thresholds can change, so confirm at checkout.

• Stylevana (C$16.99): ships from Hong Kong; free shipping over C$68 (read October 5, 2026).
• Kiokii (C$25.99): ships from Markham, ON; free shipping over C$75 (read October 5, 2026).
• Chuusi (C$26.00): ships from Vancouver, BC; free shipping over C$60 (read October 6, 2026).

At C$16.99, one item from Stylevana falls under the CBSA’s $20 exemption for mailed goods, so it shouldn’t attract duties or taxes at the door. A bigger order that clears a free-shipping minimum usually won’t.

For one item, the C$9.00 between Stylevana and Kiokii is small enough for shipping to erase it, so compare the checkout totals.

What’s in it

The brand’s own page lists 10 ingredients, as we read it on October 6, 2026. The first five, in the order printed, are Salix Alba (Willow) Bark Water, Butylene Glycol, Betaine Salicylate, Niacinamide, 1,2-Hexanediol.

Fragrance (parfum) does not appear in that list.

Formulas change, so check the bottle you receive. For how to interpret the order, read how to read a Korean ingredient list.

What stands out in our data

These notes come from the October 2026 Price Index and the ingredient list on COSRX’s own page. We haven’t tested the product on skin, so they are about price, stock and what’s printed on the label.

• Only three of five stores had it in stock. Stylevana (C$16.99), Kiokii (C$25.99) and Chuusi (C$26.00) did. KBeauty Mart and Lakinza listed it but were out of stock when we checked.
• The saving is overseas only. The cheapest in-stock Canadian store, Kiokii, is C$9.00 (53%) above Stylevana. If you’d rather wait for a Canadian restock, the out-of-stock prices were C$21.99 and C$24.17.
• The label names both a salicylate and niacinamide. The list opens with willow bark water, then butylene glycol, then betaine salicylate, with niacinamide fourth. List order isn’t the amount, but it does mean you’re getting both. If you already use a niacinamide serum, read using BHA and niacinamide together before layering.
• The base is a plant water. Willow bark water comes first, rather than plain water.
