Biotin is a water-soluble vitamin, which means it can be dissolved in water but not in oil. Therefore, it is best to use biotin powder in water-based serums.
Here are some steps to make a biotin water-based serum:
-
Measure out the desired amount of biotin powder. The recommended dosage of biotin varies depending on the individual's needs, so it is important to consult with a healthcare professional to determine the appropriate dosage.
-
Add the biotin powder to a small amount of distilled water or another water-based liquid, such as aloe vera gel.
-
Stir the mixture well to ensure the biotin powder is fully dissolved.
-
Add the biotin mixture to a water-based serum of your choice, such as a hyaluronic acid serum.
-
Mix well and store the serum in a clean, airtight container.
If you prefer to use an oil-based serum, you can try adding biotin capsules to the oil. Simply open the capsules and mix the biotin powder with the oil before applying it to your hair or skin. However, it's important to note that biotin is not oil-soluble, so it may not dissolve completely in the oil and may not be as effective as a water-based serum.
