Cos De Baha Acne Clearing Serum (Azelaic Acid Hinokitiol Clear Skin) 30ml

How do I spot a genuine imported bottle versus a refilled fake?

When your Cos De Baha serum arrives, check that the printed label sits flush against the glass with no bubbles or wrinkles underneath. The batch code and expiry date must be laser-printed clearly on both the box and the bottle itself, never handwritten or smudged. If the seal shows any sign of previous opening, air inside, or cloudiness in the liquid, reject it immediately and contact ukdirectbd within two days.

What is the right way to apply this serum, and how often should I use it?

You need only two to three drops across clean, dry skin each morning and evening—more product wastes it and does not improve results. Wait thirty seconds after applying before touching your face or applying other skincare layers so the serum absorbs fully. Most users see one 30ml bottle last between five and seven weeks at this standard dosage rate.

What should I expect when I first start using this serum?

New users sometimes notice mild warmth or slight redness in the first week as your skin adjusts to the active ingredients azelaic acid and hinokitiol. This usually settles within three to five days; if irritation worsens or persists beyond a week, reduce application to every other day. Store the bottle upright in a cool cupboard away from heat and direct light to maintain stability throughout its shelf life.
