FAST LSX Intake Manifolds
These FAST LSX intake manifolds are the only 3-piece Gen III composite manifolds proven to deliver increased performance without compromising bottom-end drivability or high-rpm horsepower. They easily bolt onto GM Gen III (LS1, LS2, and LS6) engines and are designed to work with the 92mm FAST Big Mouth throttle body. The new stylish black intake manifolds deliver terrific performance right out of the box and can be ported by the customer for even more flow. As requested by previous LSX customers, the FAST LSX intake manifolds feature the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange, and O-ring gasket and threaded insert throttle body mounts that provide increased durability.

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
Size: 1 Ounce (Pack of 1)
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.
