How Do You Spot a Real Azelaic Acid Serum from a Refilled Copy?

Genuine Cos De Baha serums arrive in sealed boxes with intact holographic features and crisp label printing that shows no smudging or wear. The glass dropper bottle itself feels substantial and moves smoothly when you test the plunger, never sticky or loose. If the seal appears cracked, the liquid looks cloudy, or the label edges are peeling before you open it, the pack has likely been handled or refilled by someone other than the manufacturer.

What Should Your First Week of Using This Serum Look Like?

Start with three to four drops on clean, dry facial skin each morning and evening, waiting sixty seconds before applying your regular moisturiser over the top. Your skin may feel slightly warm or tingly during the first few days as it adapts to azelaic acid at ten percent strength. Most users notice their skin settling into the routine within seven to ten days, at which point you can continue at the same gentle dose indefinitely.

How Long Will One 30ml Bottle Last You in Daily Use?

This bottle typically covers four to five months of consistent morning and evening application on your entire face using just a few drops per session. Storage matters greatly—keep it upright in a cool bathroom away from direct sunlight and seal the cap firmly after each use to prevent evaporation. An unopened, sealed bottle remains stable for up to two years from the date you receive it from our warehouse.
