The Scientific Benefits of Hyaluronic Acid in Pre-Makeup Skincare

When you're preparing to apply makeup, have you ever felt that your foundation doesn't adhere well, or that dry lines and caking appear by the afternoon? This is often related to a key step in pre-makeup skincare—moisturizing. Hyaluronic acid is a scientifically proven skincare ingredient that can significantly improve makeup results.

What is Hyaluronic Acid?

Hyaluronic acid is a glycosaminoglycan naturally found in human skin, especially abundant in the dermis. Its unique feature is its powerful water-retention capacity—one molecule of hyaluronic acid can lock in more than 1000 times its own weight in water. As we age, the amount of hyaluronic acid in our skin gradually decreases, leading to dryness and loss of elasticity, which is why we need to replenish it externally.

Scientific Principles: Why is it so effective when used before makeup?

1. Deep Hydration, Creating a "Water Reservoir"

Hyaluronic acid molecules have different molecular weights and play different roles in skincare:

· Large molecule hyaluronic acid: Remains on the skin's surface, forming a moisturizing film to prevent moisture evaporation.

· Small molecule hyaluronic acid: Can penetrate deep into the stratum corneum, continuously hydrating from the inside out.

Using a product containing hyaluronic acid as a pre-makeup base is like creating an "invisible water reservoir" under the skin, providing ample moisture support for subsequent makeup application.

2. Smooths skin texture and improves makeup adherence.

Well-hydrated skin has a more even and smoother stratum corneum, which directly affects the adhesion of foundation. Scientific research shows that when skin is sufficiently hydrated, makeup products can be distributed more evenly on the skin's surface, reducing caking and powderiness.

3. Strengthens the skin barrier function.

A healthy skin barrier better resists external stimuli, and hyaluronic acid not only hydrates but also promotes the repair of the skin barrier. This means that after using a pre-makeup product containing hyaluronic acid, the skin is less likely to experience discomfort or sensitivity due to dryness while wearing makeup.
