มือใหม่ค่ะ สูตรนี้เข้ากันได้ไหมคะ อยากทราบว่ายังขาดอะไรอีกไหมคะ
แอบอิงส่วนผสมจากเซรัมที่ใช้อยู่ปัจจุบันแล้วเห็นผลชัดเจน แต่เพิ่มบางตัวเข้าไป อยากลองสั่งทำใช้เองค่ะ

Formulation Feedback

This formulation includes several excellent active ingredients known for their benefits in skincare, such as Safe-B3™ (Niacinamide), Double Hyaluron Liquid, Panthenol (Vitamin B5) ExtraLite™, Zinc PCA, and Encapsulated Salicylic Acid. These ingredients are generally compatible in a water-based system.

Safe-B3™ (Niacinamide): Used at 10%, which is a high concentration suitable for addressing various concerns like oiliness, pores, and skin barrier function. The Safe-B3™ type is designed to minimize flushing at this concentration.
Double Hyaluron Liquid: Provides hydration with both high and low molecular weight hyaluronic acid.
Panthenol (Vitamin B5) ExtraLite™: Known for its moisturizing, soothing, and wound-healing properties.
Zinc PCA: Helps control oiliness and has anti-acne benefits.
Encapsulated Salicylic Acid: Offers exfoliation and pore-clearing benefits with a timed-release mechanism for gentler action.

Missing Components:

Based on the formulation provided, there are a couple of essential components missing for a stable and safe serum:

Thickener or Gelling Agent: The current formulation is primarily water with active ingredients. Encapsulated Salicylic Acid is a powder that needs to be dispersed and kept suspended in the formula. Without a thickener, the powder particles will likely settle over time, leading to an inconsistent product. A suitable gelling agent is needed to create a serum texture and maintain the dispersion of the encapsulated powder.
Preservative: Water-based formulations are highly susceptible to microbial growth. A broad-spectrum preservative system is crucial to prevent contamination and ensure the safety and shelf-life of the product.

Recommendations:

To improve this formulation, consider adding:

A suitable water-soluble thickener or gelling agent to create the desired serum consistency and suspend the Encapsulated Salicylic Acid.
A broad-spectrum preservative system to protect the product from microbial contamination.

Additionally, it is important to check and adjust the final pH of the formulation once all ingredients are combined. The optimal pH range for the stability and efficacy of ingredients like Zinc PCA and Niacinamide is generally between 4.0 and 7.0. Ensuring the pH is within an appropriate range will help maintain the quality and performance of your serum.
