KW (H.A.S) Height Adjustable Spring kits are a great alternative to conventional lowering springs. You are no longer stuck with a fixed lowering height. KW H.A.S. systems allow you to adjust the vehicle ride height with the KW height adjuster even after the kit has been installed. Your vehicle not only gets a more dynamic look, but also the steering behavior and response of the standard dampers becomes more agile. All driver assistance systems and comfort features of a factory adaptive or electronic suspension remain operational and work harmoniously with our vehicle specific spring set up. KW uses high-quality springs made of chrome-silicon steel with spring rates designed specifically for each respective OE suspension damper and wheel load. KW's expertise and engineering ensure the spring rates will pair perfectly with the different damper characteristics of your factory adaptive electronic suspension. Along with the use of high quality materials and the included KW ride height Adjustment - mechanisms, our KW H.A.S. kits always includes the vehicle-specific bump stops with dust protection system to protect your factory suspension against wear & tear caused by road grime and debris. Similar to a coilover suspension, the KW H.A.S kit allow a continuous adjustable ride height within a tested range, something not possible with conventional lowering springs. The dust protection elements and spring perches included in the delivery, when applicable, are always adjusted to the maximum technically possible lowering, typically limited by the factory dampers. With KW height adjustable springs, a sporty and harmonious driving behavior can be achieved without the driving dynamics of performance-oriented vehicles suffering. As with all KW suspension products our engineers develop vehicle specific parameters and spring specifications which undergo comprehensive testing on the Nurburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center.

Surprisingly effective
Size: 1 Ounce (Pack of 1)
I frequently have combo skin with oily, dilated pores on my nose and dryness in other areas. I got this to address blotchy redness (my skin can be especially reactive to too much moisturizer and/or too many actives). Redness Reform definitely helps to calm the redness, but I've been really surprised to see it also calming down my dilated pores and making my skin overall much more balanced. With consistent twice daily application, I find I'm able to step up my use of retinoids and AHAs without seeing increased irritation. It's been so helpful for multiple concerns that I've already repurchased to make sure I have a new bottle on hand when this one runs out! Giving 4 stars because I wish there were more product for the price. You can definitely get away with 2 small pumps to cover the face and neck if your skin is moist/hydrated after cleansing, but I find I'm liking to use just a bit more (4 pumps or so) to get really thorough coverage and hone in on the areas that need it most. The other reason it isn't 5/5 for me is because it's too thin to actually deliver on the promise of optical correction. Yes, it's green, but it's doing very, very little short-term to camouflage redness. I do like the consistency, because it does allow a little to go a long way and gives it a higher-end application feel, but it's misleading to suggest that you'll get meaningful color correction while using this product.

Love this serum

Love this serum and have already gone through several bottles. It really seems to help with small red patches on my face and the arnica helps to calm imperfections down. Great value for the price !

NOT for rosacea or ocular rosacea!!
Size: 1 Ounce (Pack of 1)
NOT for rosacea! I have rosacea and ocular rosacea. I did a test on the side of my cheek. It seemed to go OK…. When I used it on my entire face, I paid for it for two days!! Caused a nasty flare. This product has GLYCOLIC ACID, very low levels of it, but it does nonetheless. It was a disaster for me.

Like but...
Size: 1 Ounce (Pack of 1)
Was nice and light on my skin but did not see much improvement of redness after 6 weeks. No fragrance, did not irratate skin. May try another bottle incase it wasn't enough time to see results. Overall I like the product just not the results at this time.
