Feedback on Your Skincare Formulas

Hello,

Thank you for sharing your formulas and skin concerns (acne scars, melasma, wrinkles, and oily skin). You are 34 years old and prefer liquid, easily absorbed formulas.

Regarding your preference for liquid formulas for oily skin, the team advises that the absorption depends more on the overall formula composition than just being liquid. Light creams or gels can sometimes absorb faster than plain water.

Here is the feedback on your proposed formulas:

• Formula 1 (Rose Hip Oil + Q10): For very oily skin, using oil alone or in a high proportion is generally not recommended as it may feel too heavy and unsuitable.
• Formula 2:
  • The concentration of Vitamin B5 (Panthenol) at 5% is considered too high for oily skin and may result in a sticky or greasy feeling.
  • Allantoin has limited solubility in water, typically not exceeding 0.5%. To ensure it fully dissolves in your formula, the team suggests reducing the concentration to 0.25%.
  • (Note: The staff response did not explicitly address the mixing order for Formula 2, focusing instead on ingredient suitability and concentration.)
• Formula 3 (for post e-matrix): The feedback on Allantoin solubility (reduce to 0.25% for full dissolution) also applies to this formula.

Overall Recommendation:
The team suggests combining ingredients from your proposed formulas into a single, optimized formula. The key is to carefully select ingredients and adjust their concentrations to be suitable for oily skin, avoiding high levels of ingredients that can cause stickiness or greasiness. Using formulations that feel comfortable on the skin is important for consistent use and achieving desired results.

We hope this feedback is helpful!
