Review of Serum Formulation for Combination Skin (Anti-Aging, Brightening, Pore Tightening)

Okay, I can help review this serum formulation. You've provided a list of ingredients and their percentages, aiming for a serum for combination skin (ages 18-35) that targets wrinkles, tightens pores, and brightens the skin, with a desired clear, thick, fast-absorbing texture. You also mentioned having an electric mixer.

I will review the second list of ingredients you provided, as you indicated the first had incorrect percentages.

Here is the list from your second post:

• Repair Activator™ 10%
• DMAE (SkinTight MD™) Liquid 5%
• Wrinkle-Fill™ (L-Tyrosine) 2%
• Alpha Arbutin 2%
• WhiteCumin™ 2x (สารสกัดขมิ้น) 4%
• Witch Hazel (Distilled - Alcohol Free) 60.5%
• Vitamin B6 (Pyridoxine Hydrochloride) 3%
• Ethoxydiglycol 4%
• Cyclomethicone / Cyclopentasiloxane (Low-Odor) 5%
• Reservoir-Tech 3%
• SiliSolve Plus™ 1.5%

Let's check the total percentage: 10 + 5 + 2 + 2 + 4 + 60.5 + 3 + 4 + 5 + 3 + 1.5 = 100.5%. There seems to be a small excess of 0.5% in the total percentage listed. You might want to double-check the percentages to ensure they add up to exactly 100%.

Based on the ingredients and your goals:

• Anti-wrinkle and Firming: Repair Activator™, DMAE, and Wrinkle-Fill™ are included, which are relevant for addressing wrinkles and skin firmness.
• Pore Tightening: DMAE and Witch Hazel are known for their astringent and tightening properties, which can help with the appearance of pores. Vitamin B6 may also help regulate oil, indirectly benefiting pores.
• Brightening: Alpha Arbutin and WhiteCumin™ are effective ingredients for skin brightening and reducing dark spots.
• Combination Skin: The combination of water-based ingredients (like Witch Hazel, Repair Activator, Alpha Arbutin, WhiteCumin, Vitamin B6) and silicones (Cyclomethicone/Cyclopentasiloxane) is suitable for combination skin, aiming for efficacy without excessive oiliness.
• Texture (Clear, thick, fast-absorbing):
  • Clear: Most ingredients should allow for a clear or translucent serum, assuming proper mixing and solubility.
  • Fast-absorbing: Silicones and Ethoxydiglycol contribute to a smooth, non-greasy feel and aid absorption.
  • Thick: SiliSolve Plus™ is an emulsifier that helps combine the water, oil, and silicone phases and contributes to the serum's texture. As the staff mentioned, using an electric mixer is necessary with SiliSolve Plus™ to achieve the desired consistency. While SiliSolve Plus helps create the texture, the final viscosity ("thick") will depend on the overall composition and how the emulsifier system performs at 1.5% in this specific formula. It might result in a moderately viscous serum rather than a very thick gel.

Overall, the formulation includes a good mix of active ingredients targeting your stated concerns for combination skin. Having an electric mixer is crucial for successfully formulating with SiliSolve Plus™ as intended. Just double-check the percentages to ensure they sum to 100%.

Would you like me to provide more details on any specific ingredient or aspect of the formulation?
