Why choose this formula?

Calm Clarity Serum 10+ is azelaic acid for people who don’t want a cream: 10% azelaic with arginine, centella, and allantoin in a weightless, fast-absorbing serum. It works on the look of redness and uneven tone in a single light layer, ideal for oily or combination skin, humid weather, or layering under the rest of your routine. A format choice, not a strength step.

How to introduce it

Patch test first. Introduce one active formula gradually, starting with a few evenings each week. Follow the packaging directions, moisturize as needed, and wear a broad-spectrum sunscreen during the day. Stop if irritation persists.

Ingredients & formula details

10% azelaic acid · Centella · Allantoin. See the ingredient photograph in the gallery and the product packaging for the full formula details.

Learn about the ingredients
Is the serum stronger than the 10+ cream?

No. Both are 10% azelaic acid. The serum is weightless with arginine and centella; the cream is a cream. Pick by feel.

Can I use the serum and a Calm Clarity cream together?

No need: pick one azelaic active. Robust skin can alternate days, but stacking isn’t better.

Will it pill under makeup or sunscreen?

Built not to: water-light, sinks in fast, no film. Thin layer, sixty seconds, then SPF.

    Nice serum, goes on gently and feels soothing

    “This nearly scentless serum goes on gently and absorbs quickly. … I like the ingredients. Azelaic acid is not that easy to source, so I am excited to have this. This is a new brand to me, but I will definitely watch for other products. This has centella, a favorite of mine.”

    Gentle On Sensitive Skin With No Irritation So Far

    “The first positive about this serum is that I have very sensitive skin, and so far, it hasn’t caused any irritation, redness, or breakouts! … The serum is a creamy white color with a lightweight, smooth consistency. It spreads easily across the face and doesn’t feel overly heavy or greasy. There’s no noticeable scent, which I really appreciate, especially since fragrance can sometimes irritate sensitive skin. … Overall, my first impression is very positive.”

    Good For Oily & Problematic Skin

    “Feels clean once applied … Works rather well on my mature combination skin for those times when the more oily and problematic side starts to act up. Does not leave unwanted oily nor greasy residuals on the surface of the skin. … Easy to apply and it absorbs rather quickly. Does not leave the skin feeling sticky nor tacky. Works well with other skincare products and is easy to wear under makeup.”
