Glass Skin in 5 Steps: Layering Order Is 90% of the Result

Glass Skin isn't about one miracle product. It's about the order you layer. Apply a rich cream before a lightweight toner and the heavier formula sits on the surface before the thinner one can settle in. Thin first, rich last. That single rule is what this routine is built on.

Five products. Three steps shared between morning and night, plus one AM finish and one PM finish. The philosophy is simple: follow the layering order, and each texture gets the chance to do its job.

Why Order Is 90% of the Result

Lighter, water-based textures settle onto skin first; richer textures follow to seal the surface. Reverse the sequence and the heavy formula sits on top, so the lighter one underneath cannot settle in evenly. Glass Skin is built by layering order, not by any single product.

Step 1｜SK-II Facial Treatment Essence — First Essence · AM + PM

Best First Step

SK-II

Facial Treatment Essence 75mL

Over 90% Pitera — the ferment filtrate that defined what a first essence should do. A light, watery texture applied right after cleansing, chosen as the first step in this routine.

Over 90% Pitera™, in a light, watery essence texture. Applied right after cleansing, its thin consistency settles onto the surface without leaving residue — which is why it goes first in a routine built on layering order. The toner and cream that follow layer on smoothly.

"Priced at a premium, but worth it as the first step if you're building this routine from scratch." — LOUNA

Step 2｜ANUA Heartleaf 77% Soothing Toner — Toner · AM + PM

ANUA

Heartleaf 77% Soothing Toner 250mL

A soothing toner with 77% Houttuynia cordata extract. Simple, gentle formula for reactive skin.

77% heartleaf concentrate — a formula suited to calming skin that feels reactive or unsettled. Simple ingredient list, suitable for reactive skin. Chosen by LOUNA as an everyday step for its light, fast-absorbing texture.

"Light enough for a rushed morning, which is exactly why it earned a permanent spot in this routine." — LOUNA

Step 3｜COSRX Advanced Snail 96 Mucin Power Essence — Serum · AM + PM

Best Value Serum

Step 4｜Torriden Dive In Cream — Morning Finish · AM

TORRIDEN

Five types of low-molecular hyaluronic acid in a light gel — a daytime moisture-lock finisher.

Check on Amazon →

Five types of low-molecular hyaluronic acid in a lightweight gel texture that absorbs without heaviness — ideal before SPF or makeup. Chosen as the AM finish for how quickly and cleanly it settles in, true to its "Dive In" name.

"Chosen for the light gel texture that sits well under sunscreen — that's the reason it's the morning pick." — LOUNA

Step 5｜TATCHA The Dewy Skin Cream — Night Finish · PM

Best Night Cream

TATCHA

The Dewy Skin Cream 50mL

A rich night cream that locks in moisture while you sleep — TATCHA's finish for dewy skin.

Check on Amazon →

Dewy skin is Glass Skin — the same result, described differently. Richer than Torriden, and chosen as the night finish for that reason. Morning with Torriden, night with TATCHA — that contrast in texture is the point of using both.

"The richer texture makes it an easy pick for nighttime, paired with the lighter Torriden for morning." — LOUNA

Glass Skin Is Built by Order

Start with SK-II. Try COSRX first. Either works. What matters is the sequence: thin to thick, water to oil, every morning and every night. These five are chosen to be used in that order. Ready to start? Pick one from LOUNA's selection below.
