• "Sandwich" method for potent ingredients

Skincare Product Layering Rules

This guide provides simple rules for organizing your skincare routine, addressing the common confusion about which products to apply in the morning, evening, or in what order.

1. Texture-Based Application: Liquid First, Then Thick

The fundamental principle is to apply products with a thinner, more liquid consistency before those that are thicker.

• Example: Apply serums first, followed by moisturizing creams. This allows the lighter serums to penetrate the skin effectively before being sealed in by the heavier moisturizer.

2. pH-Based Application: Low pH to High pH

The order of application should also consider the pH level of your products. Start with products that have a lower pH and move towards those with a higher pH.

• Example:
  • Begin with a Vitamin C serum, which typically has a low pH of around 2 to 3.
  • Wait approximately 5 minutes for your skin's pH to rebalance.
  • Subsequently, apply serums with a higher pH, such as Hyaluronic Acid (HA) or Niacinamide (Mia).

3. The "Sandwich" Method for Potent Ingredients

When using potent or "chock mình" (meaning "shocking" or "intensive") ingredients, a "sandwich" method is recommended.

• Framework: This method involves layering a hydrating serum, then the potent ingredient, and finally a moisturizing or occlusive product.
• Example: Apply a Hyaluronic Acid (HA) serum for hydration, followed by a potent ingredient like retinol, and then finish with a moisturizing or khóa ẩm (moisture-locking) product. This approach helps to buffer the skin and minimize potential irritation from strong actives like retinol.
