Hope I don't jinx my good luck by reviewing early. The 1st time I tried it, my rosacea flared up so I was disappointed, but then I realized that my rosacea was doing its thing where it hates everything for a period of time. After I finally got it to calm a bit, I tried this again last night...and my skin this morning was so smooth and my stubborn pustules that have stayed angry for weeks are significantly smaller and less red, and my smaller closed comedones-looking rosacea pustules were also less raised. This was the only thing I used on my face last night other than my normal hydrating serum so I think it must be the cause. I'm really hopeful.
Regardless of how this works long-term, $25 is an insane steal for the quality of these ingredients. I have been searching forever for a vitamin C + tranexamic acid serum that doesn't include Niacinamide (which is in everything these days, though more and more people are realizing they have sensitivities), and isn't $90+. I'm also pleased to support a small honest business. I'm also impressed by the quality of the nice dark bottle; admittedly sometimes small business packaging looks a bit sloppy. Looking forward to exploring more products.
