Cos-IQ Intimate Brightening Roll-On Serum 80ml | With Azelaic Acid & Alpha + Beta Arbutin Complex | 60 Days Pack

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.

“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.”

I’ve been using this intimate brightening roll-on serum for over six weeks and have seen a clear improvement in the tone and texture of my skin. It’s designed for delicate areas like underarms, inner thighs, knees and bikini line, and it performs well without causing any discomfort. The formula contains ingredients known for their brightening properties, yet it remains gentle on the skin. I have sensitive skin and often react to strong actives, but this serum does not cause redness, itching or dryness. There’s no heavy fragrance or stinging sensation — just a mild cooling feel upon application. The roll-on glides smoothly and absorbs within seconds. It leaves no stickiness or residue, so I can dress immediately after use. I apply it twice daily after showering, and it fits easily into my routine. With consistent use, darkened areas have become noticeably lighter and more even. My underarms and inner elbows look healthier, and the skin feels softer and smoother to the touch. It works well for both women and men. My partner used it on his inner thighs and saw similar results with reduced pigmentation and no irritation. The 40ml bottle is compact and travel-friendly. The rollerball dispenses just enough product per use and keeps the formula hygienic. A little goes a long way, so it lasts for several weeks. This is not an instant fix — results build gradually over time. But for a non-invasive, everyday solution, it delivers reliable and visible improvement. Highly recommended for anyone looking to gently fade dark spots and achieve brighter, more confident skin in sensitive areas.

"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!"

I have been using this brightening roll-on serum for a few weeks and I am happy with the results so far. It is designed for delicate areas like underarms, inner thighs, knees and bikini line, and it feels gentle while still being effective. The roll-on applicator makes it easy to apply without rubbing or tugging the skin. It glides smoothly and cools the area slightly on contact, which feels soothing. The formula absorbs quickly and does not leave any stickiness or residue. It contains azelaic acid and a blend of alpha and beta arbutin which are known for their skin brightening properties. I noticed my underarms and inner elbows looking more even in tone after consistent use. There is no harsh smell or irritation, which is important for such sensitive zones. I appreciate that it is lightweight and non greasy. I usually apply it at night after showering and follow with moisturizer if needed. It layers well under deodorant or clothing without causing discomfort. The 40ml bottle lasts a long time since you only need a small amount per application. The packaging is hygienic and travel friendly. This serum is suitable for both women and men. My partner also tried it for mild darkening after shaving and found it comfortable and helpful. One thing to keep in mind is that results take time. You need to be patient and use it regularly for several weeks to see visible improvement. It is not an instant fix, but it works gradually without harming the skin. Overall, this is a thoughtful and well formulated product for those concerned about pigmentation in intimate or sensitive areas. Highly recommended for anyone looking for a safe, non irritating solution to uneven skin tone.
