Alpinestars - RK-7 Plasma Knee Brace

With a slim ergonomic design offering a high level of off-road performance and comfort during dynamic movement, the RK-7 PLASMA Knee Brace has been engineered to provide superior knee support, while still being lightweight, breathable, comfortable, and protective. This knee brace features a free-floating Nucleon PLASMA knee protector encased in an innovative asymmetric fiber reinforced frame construction for enhanced levels of rigidity.

  • This brace provides optimal structural integrity, rigidity and comfort, and thus reduces the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus.

  • The replaceable knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA Knee protector for the optimum blend of impact protection, flexibility and scratch resistance.

  • The replaceable strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles.

  • The extremely stable, slim-design four-point hinge system perfectly follows the articulation of the knee while the extension stops, which are available in a range from 0 to 30 degrees, assist in setting the brace to the desired maximum opening angle.

  • The stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment.

  • Nucleon PLASMA is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies. Lightweight and highly ventilated, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions.

  • The Nucleon PLASMA Knee protector is constructed from USDA certified bio-based eco-friendly and sustainable impact absorbing material.

  • Soft-touch thermoformed padding ensures the highest levels of rider comfort while keeping the knee brace securely in position. Replaceable as a spare part.

  • Soft-touch thermoformed condyle padding comes in different thicknesses for a customized fit. Replaceable as a spare part.

  • Nucleon PLASMA embedded into the shin padding for additional protection.

  • Equipped with padded X-straps backed with a non-slip material to ensure the knee brace remains securely in position while riding.

  • X-straps are profiled to avoid pinching the back of the knee when fully flexed.

  • High tensile strength buckles are robust while still being flexible for easy strapping and adaptivity.

  • Upper and lower buckles are easily locked into the closed position by a keyhole snapping system.

  • Easily exchangeable extension stops (0, 5, 10, 15, 20, 25 and 30 degrees). Replaceable (as spare parts).

Subtle but works!!
Okay there are PRICEY for the small amount you receive. I believe they work for sure and will buy them again but which they would put a FEW MORE in a pack because they are not like miracle patched and you definitely need two packs to see a significant difference.

Did nothing for hyperpigmentation, worked well on active blemish
I use these for an active blemish and they work well for reducing inflammation and redness. They are marketed for hyperpigmentation, but they didn’t seem to have much of an effect on lingering redness from an old breakout after a few uses so I decided to use them on a whitehead that popped up on my chin. I bought two packages and had passed the return window so I figured couldn’t hurt. After a few hours with this patch on, the whitehead and surrounding redness virtually disappeared. They are almost invisible on the skin IF you can remove them from their clamshell packaging without scrunching up and wrinkling the edge of patch. BIG IF!!! Most of the time I mess up the edge of the patch making the wrinkled edge visible on my face. I wear them around the house so I don’t really care about that, but it’s worth mentioning. You have to remove them from the packaging VERY carefully to keep the patch smooth. I’ve been mostly unsuccessful at removing them without scrunching up an edge. Oh well. Peach Slices makes a similar product for acne, “deep blemish microdarts”. I haven’t tried those, nor do I plan to because the amount of product that you get for either kind of micro dart is not a good value to me. I wish these were less expensive. I do like the way the micro dart feels when you apply it- kind of a satisfying stinging sensation- like the ingredients are really penetrating. I would not call it painful. A moment of sting and it’s on there doing it’s job. It stays on well while doing basic daily activities (like doing the dishes, working at a desk). Can’t say how it would hold up to something more vigorous like a jog or bike ride or anything that would make you break a sweat. I like the product and the result on blemishes, but I can’t justify the cost. A warm compress and followed by a vitamin C serum on a blemish works just as well and it’s way more cost effective, albeit less convenient. Also, the ingredients in the product description are incomplete. See photo- they contain Butylene Glycol which is sometimes irritating to my skin. Luckily, these patches didn’t irritate me. Having to 3rd party check the ingredients for cosmetics from Amazon irritates me though 😒 If these are affordable for you for the occasional blemish, I would recommend. Did nothing for hyperpigmentation and way too expensive for me to combat a full breakout or even a daily random pimple. I’ll use the ones I have but would not purchase again.

Didn’t Work for Me
This purchase was a complete waste of time and money for me. The dots did absolutely nothing to reduce the color of a sun spot on my cheek. I used them according to the instructions for consecutive days. The dots are gone, but the spot on my skin remains as dark as before. Maybe they work better for pimple discoloration.

Very Effective!
I have enjoyed all of the Peach Slices products I’ve purchased so far. These are by far my favorite. I noticed a difference after leaving one of these on overnight on a red spot where a pimple had been. It was probably 50% lighter the next day. They are very pliable and hardly noticeable on your skin. I just wish more than 9 came in a package.
