Simple Vitamin C Serum

Ascorbic Acid For Skin

Ascorbic acid or known as pure vitamin C is known as potent antioxidant for skin. However, the product in market is quite  expensive not to mention it oxidises easily. 

Ascorbic acid helps fade hyperpigmentation and brighten the skin. It is one of sought after skincare ingredients. 

We have 2 easy and simple steps in formulation pure vitamin C serum. In addition to you can adjust the pH yourself and ascorbic acid concentrate.

You can substitute panthenol in this formulation to other compatible active or plant extracts. You can also choose not to use panthenol at all. 

I a making this serum with propanediol. Propanediol is humectant that does not provide stickiness like glycerin. If you want to formulate vitamin C serum without presrvatives, you can use propanediol as a substitute of water. 

If you want to formulate this serum with vitamin E, you need solubiliser such as polysorbate 20, polysorbate 80.

You only need 4 raw materials and distilled water to start creating this serum. I made this in 50 ml bottle and it lasts around 3 months. 

I did not adjust pH on this serum because it has pH around 3.5. You can adjust it to 3 using citric acid. Remember if you lower the pH to 2.5, you might fell tingling sensation. 

If you have sensitive skin, I recommend to start formulating this serum with 5% ascorbic acid. You can work your way up to 20% ascorbic acid.
