Review: I’ve been using the Cos-IQ Brightening Underarm Roll-On Serum and it has worked really well for me. The formula feels gentle and non-irritating, making it suitable even for sensitive skin. It helps control body odour throughout the day while leaving a fresh, floral fragrance. With regular use, my underarms feel smoother and look brighter, thanks to the mild exfoliation. The roll-on format is convenient and mess-free, and it dries quickly without any stickiness. A great everyday underarm serum that combines skincare and deodorant benefits in one.
Review: The Cos-IQ Brightening Underarm Roll-On Serum is honestly one of the best underarm care products I’ve used. It combines the power of Mandelic Acid, Bioecolia, and Bio White, which work together to brighten the skin, reduce pigmentation, and gently exfoliate without causing irritation. What I love most is that it controls body odour for long hours while staying extremely gentle on sensitive skin. The texture is lightweight, non-sticky, and dries quickly—no white marks, no residue, and no discomfort. The fresh floral fragrance is subtle yet refreshing, making you feel clean all day. After consistent use, there is a visible improvement in underarm smoothness and even tone, which is a big plus for anyone dealing with darkness or roughness. It’s rare to find a roll-on that works as a brightening treatment + deodorant at the same time, but this one does both perfectly. And the quantity of 40 ml lasts long making it a value for money. For daily freshness, odour control, and brighter underarms, this product is a must-have!

It is a very good product. A lightweight product that absorbs quickly and leaves the underarms feeling fresh without any stickiness.

The fragrance feels pleasant. It smells beautiful
