Ingredient Usage Concentration, Safety, and Preservatives
คำถาม
I have a few questions regarding the usage of certain ingredients:
- Is there any harm in using Ceramide Complex at 100% concentration directly on the face? I was mixing it with Galactomyces Ferment Filtrate (Pitera), but the pump nozzle got clogged and I couldn't pump it out. So, I'm currently using it directly from the jar.
- Will there be any negative effects if Repair Activator (Bifida Ferment Lysate) and Apple Cell Extract are used at concentrations exceeding the recommended ratio, or used purely at 100%?
- Regarding Repair Activator (Bifida Ferment Lysate), it contains the preservative Phenonip, which includes parabens. Does the company have a policy to import Repair Activator that does not use paraben-containing preservatives?

Formulation Questions Answered
Here are the answers to your questions regarding cosmetic ingredient usage:
1. Using Ceramide 100%
Using Ceramide Complex or other Ceramide products at 100% concentration on the face is not harmful. However, it is also not the most effective way to use it. Ingredients like Ceramide are typically designed to work best at specific, lower concentrations when properly formulated into a base cream or lotion. Using a much higher concentration than recommended does not provide significantly greater benefits and can be wasteful. It is recommended to mix Ceramide with your regular cream base for optimal results and absorption.
2. Using Repair Activator and Apple Cell 100%
Unlike Ceramide, using ingredients such as Repair Activator (Bifida Ferment Lysate) and Apple Stem Cell Extract at concentrations higher than recommended, or at 100%, can be harmful to the skin. It is strongly advised not to use these ingredients in their pure, undiluted form. Always adhere to the recommended usage rates provided for these products to ensure safety and efficacy.
3. Preservative in Repair Activator
Regarding the preservative used in Repair Activator, the company has not received notification from the manufacturer about any plans to change the preservative system. While the product you are using may contain Phenonip (which includes parabens), the concentration of Phenonip within the Repair Activator product itself is very low (0.4%). When Repair Activator is used in a typical formulation at the recommended rate (e.g., 10-15%), the final concentration of Phenonip in the finished cosmetic product is extremely low (around 0.04-0.06%), which is considered safe for use.
