4U2 Mellow Oil Balm serves as the perfect hybrid between intensive lip care and radiant, custom-tinted beauty. This innovative formula utilises advanced pH-sensing technology to react to your body temperature, shifting into a tailored shade of pink or coral that perfectly complements your natural undertones. Beyond the immediate colour boost, the balm delivers heavy-duty hydration; sodium hyaluronate and shea butter melt upon contact, drenching dry lips in a protective, non-sticky oil layer. Palmitoyl tripeptide-1 works beneath the surface to support a plumper, more youthful appearance while locking in vital moisture. This 100% vegan formula provides a healthy, high-gloss finish entirely free from harsh alcohols or synthetic fragrances, making it an essential companion for daily wear or evening touch-ups. Why You Will Love It: Custom Colour Shift: Features pH-reactive pigments that change colour to create a unique tint tailored to your individual skin tone. Intense Moisture Lock: Blends sodium hyaluronate and shea butter to heal chapped lips and provide lasting comfort. Smoothing Peptide Action: Includes palmitoyl tripeptide-1 to help the lips look fuller and feel noticeably softer. Clean Beauty Standards: Boasts a fragrance-free vegan formula that avoids parabens and alcohol for a gentle application. How to Use: Apply the balm directly to clean lips and wait a few moments for the colour to develop as it reacts to your warmth. Layer the product to increase the glossy shine or the intensity of the custom tint.
