Question 1

How do hydrocolloid patches actually work?

Accepted Answer

Hydrocolloid is a moisture-absorbing material originally developed for wound care. When you put it over an active blemish, it pulls fluid and impurities up and out while protecting the spot from your fingers, your pillow, and the rest of the day. You'll see the patch turn white when it's done its job.

Question 2

When during a breakout should I use it?

Accepted Answer

Power Patches work best on whiteheads — spots that have come to a head. They're not designed for deep, blind cysts (no patch is). For early-stage spots, applying at night before bed and removing in the morning is the sweet spot.

Question 3

Two sizes — when do I use which?

Accepted Answer

10mm patches are for smaller spots, single bumps, and spot-treating around the nose. 12mm are for larger areas — the bigger one on your chin, or anything around the jawline. You get 28 of the 10mm and 24 of the 12mm in every pack.

Question 4

Can I wear it under makeup?

Accepted Answer

Yes. The cover is nearly invisible by design. Apply makeup over it gently with a sponge or fingers — heavy brush motions can lift the edge. Most customers say no one notices unless they're looking very closely.

Question 5

How long can I wear one?

Accepted Answer

Up to 8 hours. You'll know it's done its job when the patch turns white or cloudy. Replace with a fresh one if the spot is still active.

Question 6

What's actually in it?

Accepted Answer

Two ingredients: hydrophilic hydrocolloid and cellulose gum. No fragrance, no actives like salicylic acid or tea tree. Just the patch material itself, doing its job.

Question 7

Where do you ship?

Accepted Answer

Across Canada and the US. Free shipping anywhere in Canada. United States orders are a flat $6 CAD. Orders typically arrive in 3 to 7 business days.

Question 8

Is there a discount when I buy more than one?

Accepted Answer

Yes — buy 2 or more Power Patch packs in a single order and 20% off the product subtotal is applied automatically at checkout. Available to customers in both Canada and the US.

Question 9

What's your return policy?

Accepted Answer

If your pack arrives damaged or doesn't match the description, email info@ouiera.com within 14 days and we'll make it right. Hygiene products can't be returned once opened.

Question 10

Why should I buy here vs Amazon?

Accepted Answer

Same product either way. Buying direct supports a small team and gives us a way to reach you with care notes, drops, and the occasional 10% off. Buying on Amazon is faster shipping for Prime members. Up to you.

Question 11

Are these the same as Mighty Patch or COSRX?

Accepted Answer

Same category, same hydrocolloid science. Different formulation, different sizes, different price. We give you 52 patches across two sizes for $15 — most competitors charge more for less.

Everything you'd ask before you patched.
