How do I know this is genuine and not refilled?

Authentic Cos De Baha bottles arrive sealed with a tamper-evident band around the cap that shows no signs of disturbance or resealing. The label should display crisp printing with clear batch codes and manufacturing dates—blurry text or smudged numbers often signal a counterfeit or relabelled pack. Open the seal and smell the product; a sharp chemical scent confirms the active ingredients are present, whereas a weak or off odour suggests dilution or substitution by a refiller.

How much should I use and how often?

A few drops suffice for your entire face since this serum concentrates three potent actives in small volume. Most users apply it once daily to clean, dry skin, though you may alternate days if your skin feels sensitive during the first two weeks. Beginners often experience mild tingling or slight dryness as the retinol phase activates your skin barrier—this normalises within seven to ten days if you follow a steady routine.

What should I expect in my first month?

Your skin may look slightly brighter and feel smoother after two to three weeks of consistent use, but dramatic changes take longer. The tranexamic acid and cica ingredients work quietly to calm irritation, so you might notice reduced redness before any visible texture shift. Store the bottle upright in a cool cupboard away from heat and sunlight, and finish within four to five months of opening to preserve potency.
