Mixing and Storing Cosmetic Ingredients

Regarding your question about mixing Hyaluronic Acid powder, Vitamin C powder, and Sea Kelp Extract with water for facial application, mixing these ingredients directly with plain water and using them immediately is not recommended because:

• Hyaluronic Acid: Although water-soluble, achieving the correct gel texture requires time and specific conditions. Mixing with plain water might not yield the desired texture and can be unstable.
• Vitamin C (especially L-ascorbic acid powder): It is highly unstable when dissolved in water, especially at an unsuitable pH. It degrades easily and quickly, reducing its effectiveness.
• Sea Kelp Extract: Generally, this is a liquid extract. Applying it directly might not be suitable. It should be incorporated into an appropriate base or formulation.

Mixing ingredients for facial use requires proper formulation to obtain a product that is:

• Stable: The active ingredients do not degrade quickly.
• Safe: Has an appropriate pH for the skin and includes preservatives to prevent microbial growth, which is crucial when water is present.

Storage:

• Mixed Ingredients: If mixed with water and not used immediately, or mixed in large quantities, appropriate preservatives should be added, and it should be stored in the refrigerator to help slow down degradation and microbial growth. The shelf life will be shorter than properly formulated finished products.
• Unmixed Ingredients (Powders/Extracts): Should be stored in a cool, dry place away from sunlight and moisture. Storing in a drawer away from light is a good method, but you should check the specific storage recommendations for each ingredient. Some types may recommend refrigeration to extend shelf life.

Studying the information and proper formulation methods thoroughly before attempting to make products is important for the safety and effectiveness of the resulting product.
