DIY Vitamin C Serum: Heating and Equipment

Making your own Vitamin C (L-Ascorbic Acid) serum often involves heating to help the powder dissolve completely. However, Vitamin C is sensitive to heat, light, and air, which can cause it to degrade quickly.

• Heating to 70°C: If your formula requires heating to 70°C, it's crucial to use a method that allows for precise temperature control. A water bath (placing your container in a pot of heated water) is generally recommended over direct heat or a microwave because it provides more even and controllable heating.
• Thermometer: Yes, a thermometer is essential! To ensure you reach 70°C without exceeding it (which can degrade the Vitamin C), you absolutely need a reliable thermometer to monitor the temperature accurately.
• Microwave: Using a microwave is generally not recommended for heating ingredients like Vitamin C for DIY cosmetics. Microwaves heat unevenly, making it very difficult to control the temperature precisely. This increases the risk of overheating and damaging the Vitamin C.

Containers for Vitamin C Serum:

Vitamin C serum should be stored in airtight and opaque containers to protect it from light and air, which cause oxidation and degradation. Dark glass bottles (like amber or cobalt blue) or opaque airless pump bottles are good choices. Avoid clear containers.

Hope this helps with your DIY Vitamin C journey!
