A perfect edition to my Rosacea skincare routine
Size: 1 Ounce (Pack of 1)
Unfortunately, this doesn't fully get rid of the optical redness from my Rosacea, probably only about 30-40%. However, after using it consistently,(I'm now on my 2nd bottle, using at least twice a day), I have noticed that my skin is softer, less textured and definitely less red overall. My face gets super red especially towards the evening, but waking up in the morning I have noticed less and less redness. It kinda tingle/burns on my most sensitive areas where there's obvious inflammation, but the sensation fades as it totally absorbs into my skin. I wear it as a 2nd layer to my routine, and it wears well under makeup, just remember to moisturize after applying it, and before adding any makeup. It does also tend to pill up if you accidentally touch/rub on your face, so just be mindful of that. I am very satisfied with this serum and even gifted a bottle to my Mom. As a Rosacea Girly, I love this product and have permanently added it to my skincare routine.

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 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.
