Requires an adjustment period

What the gurus are saying

This azelaic acid hits the 10% ceiling for over-the-counter products, potent but below the 15%+ strengths dermatologists prescribe in clinic. It requires an adjustment period, but reviewers who pushed through found it worth repurchasing for the price.

"With Azelaic Acid I've got Peach Slices and Cos De BAHA. The Cos De BAHA was a little harder for me to adjust to, but now that I've adjusted, this is the product I most recently repurchased, and it costs less, I like saving money."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Azelaic acid

Azelaic acid has clinical evidence for both acne and rosacea, and it is one of the gentler options for calming redness while also working on marks left behind.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
