What the gurus are saying

Formulated to be wearable rather than peeling, this 10% azelaic acid complex earns praise for calming redness and keeping oil in check for those with inflamed or rosacea-prone skin. The formula blends free azelaic acid with a derivative for better wearability and also includes glycerinic acid to ease the appearance of irritation. Those starting out with azelaic acid might want to use it at night first, then move to twice daily as your skin adjusts.

"The azelaic acid in here is super calming. [...] I loved my first impression of this serum and it's definitely going to be one that's going to be in my routine regularly, especially during these winter months to kind of keep that redness calm down."

"And that's why I created the left un reducer serum because this is for the acne prone rosacea human. It's an azelaic acid complex that has 5% free azelaic acid and 5% of an azelaic acid derivative."

"So you're not a red oily mess. But it has this other thing called 18 glycerinic acid which will decrease the look of irritation associated with redness. So this is one that I love to use. If you find azelaic acid to be a little bit not elegant, I use it just at night. If it sits well with your skin and well with your skincare routine and makeup, you can absolutely use it twice a day."

"It was important for me to include the azelaic acid itself because that's what carries the weight of evidence, but I also wanted the derivative in there because it makes the product more cosmetically elegant, so you can actually enjoy the benefits of it and layer it into your skincare routine instead of it peeling off your face and rolling into your drawer with zero benefit."
