Serum Formula Review: Ingredient Compatibility, Solubility, and Safety for Pregnant Women

Regarding the serum formula you shared and your questions about its usability and safety for pregnant women, based on the staff's feedback:

Formula Usability:

• The staff asked about the specific type of Gel Maker used. This information is needed to assess compatibility and formulation.
• Using both Sym-White (Phenylethyl Resorcinol) and 4-butylresorcinol (Activated Resorcinol) is not recommended. They work through a similar mechanism, so there is no added benefit in using both. You should choose only one of these ingredients.
• Both Sym-White and 4-butylresorcinol require dissolution in oil. The current formula appears to lack sufficient oil to properly dissolve these ingredients.

Safety for Pregnant Women:

• According to the staff, Tranexamic Acid is not suitable for use by pregnant women and should be removed from the formula if intended for this group.
• The staff indicated that the other ingredients listed generally do not pose a problem for pregnant women.

In summary, to finalize the formula and ensure its suitability and safety for pregnant women, you would need to:

1. Specify the type of Gel Maker.
2. Remove Tranexamic Acid.
3. Choose either Sym-White or 4-butylresorcinol, but not both.
4. Ensure there is an appropriate oil phase in the formula to dissolve the chosen ingredient (Sym-White or 4-butylresorcinol).
