What Real Women Are Saying About Osby
Real experiences from real customers who love our postpartum firming cream.
Smoother Skin I Never Thought I’d Get Back
After pregnancy my belly felt loose, dry, and my stretch marks looked so dark. I honestly didn’t believe a cream could help, but B-FLAT proved me wrong. Within a couple weeks my skin looked noticeably smoother and the marks looked lighter and softer. After a month, my belly felt firmer and way more hydrated — like my skin finally bounced back. I feel confident getting dressed again. Absolutely worth it.
My Stretch Marks Look So Much Softer
I’ve had deep, dark stretch marks since my first pregnancy and nothing ever made a difference. This cream genuinely shocked me. After a couple of weeks my marks started looking lighter and less textured, and my skin felt hydrated instead of dry and tight. Now at six weeks, the whole area looks smoother and more even. I finally feel good looking at my stomach again.
Finally Something That Actually Firms My Belly
Postpartum skin is no joke. My belly felt loose and crepey, and I hated how uneven it looked. B-FLAT made the biggest difference — my skin feels firmer, tighter, and so much smoother. Even my husband noticed. I’ve tried expensive oils and they didn’t do half of what this did. This is now part of my daily routine, no question.
