• Recommended Percentage: The suggested usage rate for Prebio-care is 1-5%, with 3% being the recommended concentration.
• Mixing Method: Add Prebio-care to the water phase of your serum formulation.
• Benefits: Adding Prebio-care can enhance the serum's benefits by:
  • Supporting the growth of beneficial bacteria on the skin (skin normal flora).
  • Helping to control harmful bacteria, including those that can contribute to acne.
