Worked like a charm
Style: Bundle, Size: 2 Piece Set
I’ve tried other acne patches before and they’ve always pulled excess oil out of my pores, which ended up drying, scarring, and leaving behind a dry patch when compared to the rest of my face. These effects were especially bad for my cystic acne, which always ended up more inflamed and painful after treatment. The Rael hydrocolloid patches gently pulled out all of the sebum from several pimples that I’d avoided picking at; with other brands, the patches only pulled anything out from pimples that had already been picked at/burst. The micro needle patch also relieved my cystic acne overnight. The pimple is no longer inflamed or painful. When I took the patch off, I could see the liquid and oils that it had pulled out BUT didn’t experience the scarring I have with other patches. Other reviews mention that the patches are fragile, but I don’t necessarily think that’s any different from the other brands I’ve tried. I had no problem trying to get one out of the package on the first try. Overall, I think these are a really good fit for folks with oily skin who experience scarring with other patches. These definitely pull more sebum and not as much oil, so you should see your pimples decrease in size without adding to the inflammation. The patches adhere well and stayed on all night without peeling off (even though I’d accidentally bunched up some edges on the hydrocolloid patches when applying). I’m definitely going to keep a stock of both types readily available!

Praise Rael.
Style: Bundle, Size: 2 Piece Set
I suffer from cystic acne (on my chin and jawline, so probably connected to hormones) as well as dematillomania, or skin picking disorder. It's so hard for me to not pop the big honkers, especially when these painful zits have been around for days/weeks. All I want is clear skin, but cystic acne combined with skin picking leaves me with scars that take months to fade even when I'm pimple-free . I've been using Rael's Miracle Patch (pink package) for awhile. This is a great product, and works best on more surface-level zits. Last night, I tried the Acne Healing Patch (green package) on a persistent cystic zit I've already tried to extract, plus another cyst brewing on the other side of my chin. I've used so many different products to treat cystic acne, but nothing has worked like Rael's Acne Healing Patch. I kept the patches on overnight, and in the morning I found both had reduced significantly in size. The zits are well on their way to healing, and I finally feel like I will be able to treat cystic blemishes effectively and go concealer-free in the coming months. I never write reviews, but I felt I should share this experience with Rael patches. Acne can be so mentally debilitating, and I've been helped by a lot of fellow acne sufferers who share their experiences in product reviews. I hope my review is helpful for someone else. Thank you Rael, for a truly game-changing cystic acne treatment!

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.
