Question 1

Will these strips cause sensitivity?

Accepted Answer

Pürple. is peroxide-free and uses PAP (Phthalimidoperoxycaproic acid) as the active. Most people report no tingle, sting, or sensitivity. If you have severely sensitive teeth, start with shorter sessions every other day.

Question 2

How fast will I see results?

Accepted Answer

Color-correcting purple pigments give an instant brightening effect after the first 30-minute session. PAP-based whitening compounds over time — most users see clear shade improvement after 7 consecutive days.

Question 3

Are they safe for daily use?

Accepted Answer

Yes. The formula is enamel-safe and designed for daily use during a 7–14 day course. We recommend a maintenance session 1–2× per week afterwards.

Question 4

How long does shipping take?

Accepted Answer

US orders ship within 1 business day and arrive in 3–5 business days. International shipping takes 7–14 business days. Tracking is included on every order.

Question 5

What's the return policy?

Accepted Answer

We offer a 30-day brighter-smile guarantee. If you don't see a visible improvement after a full 7-day course, email hello@purple.co for a refund — no need to return the strips.
