The Art of ""Sok-Gwang"": Achieving Inner Radiance

Key Takeaway: Sok-Gwang isn't about oiliness. It's about plumping the skin cells with hydration from the inside out, creating a natural light reflection.

What is Sok-Gwang?

In the world of K-Beauty, trends come and go, but ""Sok-Gwang"" (lit. Inner Light) has established itself as the ultimate goal for 2024. Unlike the ""Glass Skin"" of 2018 which prioritized a high-shine, almost wet surface finish, Sok-Gwang focuses on the health of the dermis layer. It implies that the skin is so healthy and hydrated that it glows from within, even without makeup.

The difference between surface oil and deep hydration is visible in pore texture. The difference between surface oil and deep hydration is visible in pore texture.

The Medical Approach: Skin Boosters

Achieving this look with topical skincare alone is difficult because most molecules are too large to penetrate the dermis effectively. This is where the Korean innovation of ""Skin Boosters"" comes into play. By injecting hyaluronic acid, polynucleotides (PN), and amino acids directly into the mesoderm, clinics can artificially create this environment of hyper-hydration.

Top 3 Ingredients for Inner Radiance

• Polynucleotides (Rejuran): Sourced from salmon DNA, this heals the skin barrier.
• Non-Crosslinked HA: Provides immediate hydration without adding volume/filler effect.
• Glutathione: Often used in ""White Jade"" injections to brighten skin tone.

Tip: Drink at least 2L of water per day for 3 days post-procedure to maximize the swelling of the HA molecules for better hydration results.
