Custom Serum Formulation: Safety and Compatibility Check

Based on the formula you provided and the response from the staff, this serum formulation appears to be safe for skin application and the ingredients are compatible.

The formula uses common cosmetic ingredients:

• Natto Gum and Pro Polymer act as thickeners to give the serum texture.
• Green Tea Extract provides antioxidant benefits.
• Olive Oil and Jojoba Oil are emollients that add moisturizing properties, even at low percentages.
• PE-1 Aqua is included as a penetration enhancer.
• Mild Preserved (Ethylhexylglycerin & Caprylyl Glycol) is a standard preservative blend to prevent microbial growth.
• DI Water is the main base.

The staff confirmed that the formula can be mixed and poses no danger to the skin. As they mentioned, assessing the efficacy would depend on your specific skin type and goals.

It's always recommended to perform a patch test on a small area of skin before applying any new product extensively, to check for individual sensitivity.
