10% Vitamin C Serum (basic)

Ever heard of Vitamin C serum? It's like a magic potion for your skin! This serum is packed with 10% L-ascorbic acid, the most active form of Vitamin C. Why does that matter? Well, because Vitamin C is a superhero antioxidant for your skin, fighting off all kinds of nasties like UV rays and pollution that can make you look older than you are.

Our serum formulation strikes a perfect balance between getting the job done and being gentle on your skin. 

Want to whip up your own batch? Our DIY recipe is easy and will take you just 5 minutes, and you don't need any fancy equipment. Plus, you can tweak the amount of Vitamin C to suit your skin's needs - more for extra oomph, less if you're worried about irritation.

Oh, and here's a little tip: for a serum that really packs a punch, aim for 5-20% L-ascorbic acid with a pH lower than 3.5. Trust us, your skin will thank you later!

This formulation makes 200g and is a 10% Vitamin C product, but can be scaled to suit.

METHOD:

1. Sterilise Equipment: Before starting, ensure that all equipment (beakers, stirrers, bottles, droppers) are thoroughly cleaned and sterilised. You can sterilise equipment by boiling them in water for 10-15 minutes or using a sterilising solution as per the manufacturer's instructions. Allow the equipment to air dry in a clean environment.

2. Prepare Base Solution: In a clean, sterilised beaker, combine distilled water and glycerin. Stir until fully mixed.

3. Dissolve L-Ascorbic Acid: Slowly sprinkle L-ascorbic acid into the water-glycerin mixture while stirring continuously until completely dissolved.

4. Add Remaining Ingredients: Add hyaluronic acid, ferulic acid, and vitamin E to the mixture. Stir well to ensure even distribution.

5. Adjust pH: Check the pH of the mixture. Adjust the pH to around 3.5 - 4 using the pH adjuster (triethanolamine or sodium hydroxide). Add the pH adjuster slowly while monitoring the pH until the desired range is achieved.

6. Add Preservative: Once the desired pH is reached, add the preservative and mix thoroughly.

7. Transfer to Sterilised Container: Transfer the serum into a clean, sterilised bottle or dropper.

8. Label the Bottle: Label the bottle with the product name, date of formulation, and ingredients list.

9. Store Properly: Store the serum in a cool, dark place away from direct sunlight to preserve its stability and efficacy.

 Enhancing a Vitamin C serum can be achieved by incorporating ingredients that complement and boost its effectiveness. Here are some simple yet potent additions:

Aloe Vera Gel: Adds soothing and hydrating properties to the serum, making it suitable for sensitive skin and enhancing the overall moisturising effect.

Glycerine: A natural humectant that helps draw moisture into the skin, improving hydration and giving the serum a smoother application.

Green Tea Extract: Rich in antioxidants, it complements Vitamin C’s protective benefits and adds anti-inflammatory properties to the serum.

Niacinamide (Vitamin B3): Helps to brighten the skin, improve elasticity, and reduce fine lines and wrinkles, working well alongside Vitamin C for a comprehensive anti-aging effect.


Please note that this is a basic formulation. Depending on your specific needs and preferences, you may want to adjust the ingredients or concentrations. Additionally, it's important to conduct proper stability testing and ensure good manufacturing practices when producing skincare products for distribution or personal use.
