Had to buy new jeans... not mad about it
I started using OSLI because I was desperate before a vacation. I didn't expect much honestly. By week 2 my bloating was noticeably down and by week 4 my jeans were literally falling off me. I've never had a product actually do what it says. Already subscribed so I never run out.
The warmth is REAL
Okay so I put the patch on and within like 2 minutes I could feel this deep warm sensation spreading across my stomach. It's not hot or uncomfortable — it's actually really soothing. Almost like a spa treatment on your belly. That alone is worth it but the fact that my midsection looks tighter after a few weeks? Obsessed.
Skeptical husband is now a believer
My husband rolled his eyes when I ordered these. Three weeks later he asked me what I've been doing differently because my stomach looked flatter. When I told him it was a patch he didn't believe me. Now he wants to try them himself lol.
Better than the waist trainer I wasted money on
I've spent hundreds on waist trainers, detox teas, body wraps — you name it. This is the first thing that actually made a visible difference without me being miserable the entire time. I just put it on before bed and wake up feeling lighter. Should have found this sooner.
Perfect for my bloating after meals
I get really bad bloating after eating, especially at night. I started putting the patch on after dinner and the difference in how I feel the next morning is night and day. My stomach is flat when I wake up instead of puffy and swollen. This is a permanent part of my routine now.
Just reordered for the third time
I don't usually leave reviews but this product genuinely earned it. I'm on my third box. My lower belly was always the area I was most self-conscious about and nothing ever touched it. Averro is the first thing that actually made me feel confident in a crop top again. The herbal smell is really nice too.
Mom of 2. This is my secret weapon
I don't have time for the gym with two kids under 4. I needed something I could do while sitting on the couch after bedtime and this is literally it. Peel, stick, watch my show, done. My postpartum pooch has gone down significantly in 5 weeks. I tell every mom I know about these.
Shipping was fast and packaging is beautiful
Ordered on Monday, arrived Thursday. The packaging actually looks and feels premium, not like the cheap Amazon stuff I've tried before. The patches themselves are high quality, they stick well, and the herbal balls smell amazing. You can tell this is the real deal and not some knockoff.
Bought for myself and ended up gifting to my whole friend group
I originally bought one box to try. Loved it so much I ordered the 3-pack bundle and gave boxes to my two best friends. Now all three of us use them and we literally text each other every morning about how flat our stomachs are. It's become a whole thing. Best impulse purchase I've made this year.
