Great for humid climates like Kampala Birch sap replaces water as the base, so it’s packed with amino acids, minerals, and antioxidants while being less irritating than plain water. It hydrates without feeding acne-causing bacteria. Tea tree gives mild antimicrobial benefits and allantoin soothes. Use AM and/or PM as your last step before SPF. 1-2 pumps is enough.
