Serum Formulation Issue with DMAE and Pro Polymer: Adjusted Formula for Hand Mixing

Question

I would like to formulate a serum by hand using the following ingredients:

Tranexamic Acid (Trans-White™) for whitening
Propylene Glycol for texture
DMAE (SkinTight MD™) Liquid for lifting (I already have this but don't use it often)

Are these ingredients compatible, and how can I formulate a serum with them, considering I will be mixing by hand?

Hello,

Regarding the formula you inquired about, the staff previously advised that adding DMAE (SkinTight MD™) Liquid when using Pro Polymer as a thickener can cause the formula to become too thin, especially when mixing by hand without a high-speed mixer.

Therefore, the staff recommended omitting DMAE from this formula.

Based on the staff's advice and your proposed ingredients (excluding DMAE), here is a suggested adjusted formula and mixing instructions for a total of approximately 100g:

Adjusted Formula:

Distilled Water: 79 ml
Double Hyaluron Liquid: 5 gram
Copper Peptide (GHK-Cu): 3 gram
Safe-B3 (Vitamin B3): 3 gram
Vitamin B5: 2 gram
Tranexamic Acid (Trans-White™): 3 gram
Propylene Glycol: 4 gram
Phenoxyethanol SA (Preservative): 1 gram
Pro Polymer: 0.5 gram

Mixing Instructions:

Combine Distilled Water, Double Hyaluron Liquid, Copper Peptide (GHK-Cu), Safe-B3, Vitamin B5, Tranexamic Acid, and Propylene Glycol in a container. Stir well until all powder ingredients are completely dissolved and the mixture is clear.
Add Phenoxyethanol SA and stir to combine.
Gradually add Pro Polymer while stirring continuously until the powder is fully dispersed and dissolved, and the desired serum consistency is achieved. You can add slightly more Pro Polymer (0.1-0.2%) if you prefer a thicker texture, but note that this may require more vigorous mixing.

This adjusted formula should be easier to mix by hand while still providing the benefits of the other active ingredients.

Thank you.
