"Honestly didn't think this would do anything. I've bought so many lip products that promise the world and end up in the drawer. But my sister kept going on about it so I tried it. Around week 3 my husband goes "did you get your lips done?" and I've literally never been more satisfied by a sentence in my life. No I did not get my lips done. I just finally found something that works."

Does it sting or burn? +

No. We left out the ingredients that cause that. Most lip plumpers use irritants that make your lips swell up for an hour and then go back to normal — that burning feeling is the product irritating your skin on purpose. We skipped all of that. We use peptides instead, so there's nothing to feel. You put it on, it absorbs, you forget about it. It works while you're not thinking about it.

How long before I see results? +

Most women notice their lips feel softer and more hydrated within 5–7 days. Visible fullness typically appears between weeks 3–6 with consistent twice-daily use. The peptides work by stimulating your lips' own collagen production, which is a gradual process — but the results are cumulative and last as long as you keep using it. This isn't a temporary effect that disappears when you wipe it off.

Why is this better than the plumpers I've already tried? +

Because those wear off. Every plumper you've tried at Sephora gives you 2 hours of slightly swollen lips and then you're back to where you started. We made something that builds over time so you stop needing to reapply, overline, or think about your lips at all. The goal isn't lips that look good while the product is on — it's lips that look good when nothing is on.

What if it doesn't work for me? +

We offer a 60-day results promise. If you don't see visibly fuller lips after 60 days of consistent twice-daily use, email us for a full refund. Keep the product — we don't need it back.

Can I pause or cancel my subscription? +

Yes, anytime. No commitments, no hoops. You can pause, skip a month, or cancel entirely from your account page in about 30 seconds. We'd rather you stay because the product works than because we made it hard to leave.

"I stopped overlining. They just look like that now."

"I used to overline every single morning. Like I couldn't leave the house without doing it. I'm on month 2 now and I stopped. Not because I decided to stop, I just forgot one morning and looked in the mirror and was like oh. They just look like that now."

"Cancelled my filler appointment."

"I was this close to booking filler. Like I had the appointment saved in my phone. My friend sent me this instead and said just try it for 6 weeks first. My lips aren't dramatic or anything, they just look like they did 10 years ago. Fuller, softer, more like me. Cancelled the appointment."
