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.

• YesStyle (C$20.63): Ships from Hong Kong. Free shipping over C$75 (read October 5, 2026).
• KBeauty Mart (C$24.99): Ships from Canada. Free shipping over C$65 (read October 6, 2026). Site banner says C$65. The shipping policy page says C$59.
• BeyondRx (C$27.99): Ships from Toronto, ON (99 Pharmacy). Free shipping over C$99 (read October 7, 2026). Free over C$99 by Chit Chats, C$129 by Canada Post Regular Parcel. Free over C$59 in the Toronto area.
• BSW Beauty (C$30.99): Ships from Toronto, ON. Free shipping over C$100 (read October 6, 2026). Threshold is before tax. C$9–13 flat rate below it.

At C$20.63, one item from YesStyle is above the CBSA’s $20 exemption for mailed goods, so duties or taxes, and possibly a carrier handling fee, can be charged on delivery.

For one item, the C$4.36 between YesStyle and KBeauty Mart is small enough for shipping to erase it, so compare the checkout totals.

Fragrance (parfum) does not appear in that list.

What stands out in our data

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

• Two ferments come before water. Bifida ferment lysate is 1st and galactomyces ferment filtrate is 2nd. Water is 5th.
• Cheaper than Torriden overseas, dearer in Canada. At each serum’s cheapest store, Numbuzin costs C$41.26 per 100 ml against Torriden Dive-In’s C$46.02. At Canadian stores only, it’s C$49.98 against C$46.02.
• Four stores had it in stock, including BeyondRx at C$27.99, which we started tracking this month.
• Niacinamide is 6th of 27. The niacinamide page covers what the research says.
