9. Active Resveratrol: 3%
10. Pep-Coll: 3%

13. 1,2-Hexanediol: 3%
14. Cell-Energy: 2%

Answers to Your Questions

1. Redundancy, Inappropriate Amount, or Incompatibility:

   • DMAE: The staff recommended removing DMAE (10%) as it is an electrolyte and incompatible with Satin Cream Maker.
   • LipidSoft CC: The staff recommended reducing LipidSoft CC from 15% to 5%. Combined with Sweet Almond Oil (5%), the total oil phase is 10%, which is sufficient for combination skin and helps avoid a greasy feel.
   • Penetration Enhancer: PE-1 Aqua (2%) was deemed unsuitable for formulas with oil-soluble actives. The staff recommended replacing it with Phospholipid (3%) if you have a mixer or Reservoir-Tech (3%) if mixing manually.
   • Potential Reductions: The staff suggested potentially reducing Repair Activator (from 10% to 5%), Vitamin B5 (from 3% to 2%), and Willow Bark Extract (from 10% to 5%). However, they noted that Willow Bark Extract can remain at 10% if melasma is severe. These reductions aim for a more balanced formula, but the original percentages are also possible depending on desired intensity.

2. Adding Essential Oil:

   • The staff could not comment on potential scent clashes.
   • They strongly advised caution when adding essential oils as they can cause skin irritation, especially certain types like Tea Tree Oil.

3. Replacing Repair Activator with Plankton Extract:

   • The staff explained that while no ingredient is a perfect replacement for another in terms of exact efficacy, both Repair Activator (Bifida Ferment Lysate) and Plankton Extract GP4G are water-soluble and compatible with this formula. You can use either, but they have different specific benefits.

4. Using Store Products for Non-Drying Dish Soap:

   • The staff explained that making dish soap less drying typically involves using lower concentrations or milder types of surfactants. This reduces the removal of natural skin oils, but also reduces the effectiveness in removing grease from dishes.
   • They suggested that the best methods to prevent dry hands when washing dishes are wearing gloves or applying hand cream immediately after washing.

Remember that consistent use of high-SPF sunscreen is crucial for managing melasma.
