It is cruelty-free, vegan, and gluten-free, aligning with a clean beauty mindset.

• Aluminium- and baking soda-free formula designed for sensitive underarm skin
• AHA based serum element that gently exfoliates, softens, and nourishes the skin
• Fast-drying, non-staining action compatible with daily outfits
• Cooling rollerball delivers a refreshing, soothing feel on contact

What to expect and how to use

Apply as part of your morning routine or post-workout care. The serum-roller blends into a light, breathable layer that dries quickly, so you’re ready to move on with your day. Some users notice gradual improvements in skin texture over time, while others simply enjoy the soft, clean feel and long-lasting comfort. For best results, use daily and allow a moment for the product to dry before getting dressed.

• Shake gently to blend the serum before every use
• Roll onto clean, dry underarms and wait for it to dry completely
• Reapply as needed; daily use supports a consistent routine

Clean beauty, transparent choices

Kosas Clean emphasizes a straightforward, skin-first approach. The formula excludes fragrance and many potential irritants, while remaining vegan, cruelty-free, and gluten-free. The result is a product designed to feel light on skin and easy to wear under everyday clothing—an option for those seeking a beachy-clean, no-fuss experience.
