I’ve been using this gel serum for a while and finally I’m ready to share the formula. This serum is an aqueous gel containing the usual hydrating ingredients that I use in my face creams, but much more concentrated. I use just a drop or two after my weekly face cleansing.
Formula
Ingredient | % |
Water | 28,5 |
Sodium hyaluronate (3% gel) | 20 |
Sodium lactate (60% solution) | 10 |
Salix Nigra (Willow) Bark Extract (10% salicylic acid)* | 10 |
Glycerin | 10 |
Sodium PCA | 5 |
Panthenol (75% solution) | 5 |
Inulin | 3 |
Allantoin | 0,5 |
Xanthan gum | 0,5 |
Benzyl alcohol-dehydroacetic acid | 0,5 |
Potassium sorbate (20% solution) | 1 |
After you mixed all these ingredients, check the pH value. It must not be higher than 6 – I keep it around 5. Then you can add the following ingredients:
Ingredient | % |
Zinc PCA | 1 |
Urea | 5 |
Sodium lactate/lactic acid buffer (0,2 M/0,1 M, pH 4) | 5 |
And that’s it!
