Layer Separation and Shaking Requirement for Fluid Light Sunscreen
คำถาม
## Question regarding Fluid Light Sunscreen (Compare to Anessa)
I have a question about the usage of this product. I noticed that when the product is left sitting for a while, it naturally separates into distinct layers.
1. Is it normal for the `Fluid Light Sunscreen` formulation to separate like this?
2. Is it correct that I must shake the bottle well before every use?
Please clarify if this behavior indicates any stability issues or if it is simply a characteristic of the formula.
คำตอบ
Yes, your observation is completely correct and normal for the Fluid Light Sunscreen (Compare to Anessa).
This product is a fluid sunscreen that contains a high concentration of solid UV filters, such as Zinc Oxide and Titanium Dioxide, along with powders like Talc and Corn Starch. Over time, these solid particles naturally settle at the bottom, causing the product to separate into layers.
It is absolutely necessary to shake the bottle well before every use.
Shaking ensures that the UV filters and other solid components are evenly dispersed throughout the liquid base. This is crucial for two main reasons:
- Achieving the Stated SPF/PA Protection: If the UV filters are not evenly mixed, the layer you apply may not contain enough active ingredients to provide the full protection (SPF50+/PA++++).
- Ensuring a Consistent Texture: Shaking helps the product apply smoothly and evenly on the skin.
