Glass skin: what the Korean routine actually does, and what is just a filter

"Glass skin" is a Korean phrase: skin so smooth and hydrated that light reflects off it like glass. Half of what you see on Instagram is a filter and a ring light; the other half is achievable, not by getting fairer, by getting hydrated.

Three things make glass skin

1. 1Water: enough water in the top layer and light lands evenly. Dry skin scatters light and looks dull.
2. 2Smoothness: a build-up of dead cells is rough; light exfoliation evens it.
3. 3Even tone: fewer marks and less redness, the slowest part.

Hydration layering (the real technique)

• The "7 skin method" need not be literal: two or three layers of a hydrating toner, pressed in by hand, the next while the skin is still damp.
• Then an essence (snail or hyaluronic), then a cream to seal it. Layered water without a cream simply evaporates.
• A hydrating sheet mask or sleeping mask two nights a week.

Exfoliation

One or two nights a week, PHA or a mild AHA (lactic). No scrubs: grains make micro-scratches and the skin looks rougher.

Glow ingredients

Rice, niacinamide, alpha arbutin, vitamin C: slow and safe. A "glow" cream with mica or shimmer is makeup, not skincare; it washes off.

The four-week plan

• Week 1: double cleansing + three toner layers + essence + cream, sunscreen in the morning. Nothing else.
• Week 2: add a sheet mask two nights a week.
• Week 3: add PHA/AHA one night a week.
• Week 4: add a brightening serum (rice/niacinamide) in the morning. Photograph and compare with week 1.

What does not give glass skin

Whitening creams, harsh scrubs, acids every night, ten products in one day. And large pores or marks do not turn to "glass"; they have their own routines: pores, marks.
