I was looking for an organic body scrubber that created lots of suds and was easy to dry without getting moldy. The Cleanlogic body scrubbers fit the bill. I deducted a star because although they are organic, easy to hang dry, create lots of suds and thoroughly exfoliated my body, they’re expensive, in my opinion. I’ve tried different brands and different kinds of scrubbers- natural loofahs, silicone hand exfoliators, body wash cloths- they all had their own shortcomings. The Cleanlogic has been one of my favorite body tools but I haven’t decided if it’s worth the cost of adding to my subscription or buying them on occasion when I want to splurge.

Perfect cartridges for my Dr. Pen M8 – sterile, secure, and seamless fit

I've been using these replacement cartridges with my Dr. Pen M8 for a couple weeks now, and they're a standout. First off, the packaging is top-notch – everything arrived tightly sealed with no damage, which is crucial for sterile medical-grade supplies like these. No leaks, no mess, just clean and professional presentation right out of the box. What really sets these apart is how flawlessly they integrate with the Dr. Pen M8. They snap in effortlessly with a secure lock, no wobbling or compatibility issues during sessions. The single-use design suspended in individual sterile packaging gives real peace of mind – I can tell they're fresh and uncontaminated every time, which is non-negotiable for at-home microneedling. Pros: Excellent sterile suspension packaging prevents contamination Perfect fit and function with Dr. Pen M8 High-quality build feels reliable for multiple uses No real cons here – these cartridges perform consistently and make the whole process smoother. If you're running a Dr. Pen M8, these are a smart, hassle-free choice that delivers on hygiene and performance. Highly recommend for anyone serious about clean, effective treatments
