Cos-IQ Intimate Brightening Roll-On Serum (Pack of 3 x 40ml) | Azelaic Acid & Alpha + Beta Arbutin Complex | For Dark Underarms, Inner Thighs, Knees | Fragrance-Free Lightening Serum for Women & Men | 120ml

I really liked this roll-on serum concept—it’s super convenient and mess-free. The packaging is travel-friendly and hygienic, perfect for targeted application on dark spots and pigmented areas. The formula feels lightweight, absorbs quickly, and doesn’t sting or irritate my skin. With consistent use, my skin looks calmer and more even. Great option for beginners and anyone who prefers easy skincare without overdoing it. Definitely worth the price.

I have used Peach Slices roll on before but getting it in India is very difficult, so I bought Cosiq thinking it will be similar. And yes, it is quite close. Both help after hair removal. Skin feels smoother and less rough with time. Peach Slices felt a little strong on my skin, but Cosiq is more gentle. No burning, no itching. Roll on is easy to use. Dries fast. Not sticky. After using it regularly, skin looks better and more even. It does not work in one day. Takes time. But it works slowly. If Peach Slices suited you, Cosiq will also suit you. Same type of work, just softer. Good product.

Roll on serum best for all skin tone is not oil and also skin protected and effective on apply few days and make soft skin and is no oil it’s hydration best appearance on skin

“Very easy to use roll-on with a light, non-sticky texture. It feels gentle on the skin and absorbs quickly without irritation. With regular use, the skin looks more even-toned and smoother. Results are gradual but noticeable.”

Have been using the product for almost a month or more. Have seen slight pigmentation reduction… but it is a game of patience.

My body thanks to the roll-on everyday after my shower and my pits stay bright with my dark spots fading slow and no bad smell lately. It last for the whole day. Does'nt have any skin issues after using, satisfaction is in so good. Go buy it stock is limited. Value for money! Great Product.

"This is so much easier to use than creams that get everywhere. The roll-on applicator is super hygienic and allows for precise application on underarms and knees. I love that it’s powered by Azelaic Acid and Arbutin—high-quality ingredients that actually work. After three weeks of nightly use, my dark patches have visibly faded, and my skin feels much smoother. Great value for the results it delivers!"

This roll-on serum is easy to use and feels gentle on the skin. It absorbs well without causing irritation or stickiness. With regular use, the area looks brighter and more even toned. Good quality product and convenient for daily care.

Easy to use. Will update when I start seeing a difference.
