Compatibility and Formulation of Vitamin C, Glucosamine, Glutathione, B3, Tranexamic Acid Mixture

Okay, let's break this down in simple terms.

Based on the previous reply, yes, the ingredients you listed (Vitamin C, Glucosamine, Glutathione, Vitamin B3, and Tranexamic acid) can be mixed together.

However, there are important things to consider, especially regarding pH (how acidic or alkaline the mixture is):

• pH is crucial for stability: The previous reply mentioned that if the pH is too low, some ingredients might lose quality. If the pH is too high, Vitamin C will degrade quickly. Each ingredient works best and stays stable within a specific pH range.
• Litmus paper limitation: Using litmus paper is a good thought for checking pH, but it only gives a general idea (like acidic, neutral, or alkaline). For skincare formulations where stability depends on a precise pH range, you usually need a more accurate tool like a pH meter. Getting the pH just right is tricky and important for the mixture to be effective and safe.
• Storage: As the previous reply advised, it's very important to store the mixture in the refrigerator and keep it away from sunlight. This helps slow down the degradation of the ingredients.

Mixing active ingredients like these at home can be challenging because getting the right concentration, pH, and ensuring stability is difficult without proper knowledge and tools. While the ingredients can be mixed, achieving a stable and effective product requires careful formulation.
