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 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.”

After using it for a while, I have noticed smoother and more even-toned skin. No burning or discomfort, skin friendly.

I’ve been using this Intimate Brightening Roll-On Serum for a few weeks now and overall I’m happy with it. The roll-on applicator is very convenient and hygienic for intimate areas. The texture is light and absorbs quickly without any strong fragrance. I noticed mild lightening of dark patches and smoother skin tone but it took consistent use before I saw changes. It didn’t irritate my skin, although I started with alternate-day use and then increased to daily.

Nice product Use it for about 1 week and can see changes Light and easily absorbing

"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’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.
