I've been using the Cos-IQ Brightening Underarm Roll On Serum for a couple of weeks, and the results are genuinely impressive! The formula with Bioecolea, Mandelic Acid, and Bio White works beautifully on my sensitive skin. It absorbs quickly, doesn't leave any sticky feeling, and gives a clean, smooth finish. What I love most is the visible brightening—my underarm skin looks clearer and more even-toned. It also controls body odour effectively, keeping me fresh all day. The fresh floral fragrance is gentle, not overpowering, and lasts for hours. Another big plus: it doesn't irritate sensitive skin at all. This roll-on feels like a skincare product rather than a deodorant. Highly recommended for anyone looking for brightening + odour control + gentle daily care. Totally worth it!

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 lightweight product that absorbs quickly and leaves the underarms feeling fresh without any stickiness. Its brightening ingredients help lighten dark patches and even out the skin tone with consistent use, and you can see visible improvement in a few weeks. It also works well as a deodorant, reducing odor and keeping you comfortable throughout the day. The roll-on applicator is convenient and mess-free, and the soft fragrance feels pleasant. Overall, it’s a great choice if you’re looking for an underarm product that brightens, smoothens, and keeps you fresh daily.
