On September 1, 2026, Beauty of Joseon launched the Hanbang Glass Serum Stick, the first SPF 50+ glass-skin booster stick.
Dr.
Jart+ followed with a 2026 edition glass-skin mask, and Sulwhasoo, Anua, and COSRX shipped autumn glass-skin launches and edits of their own.
This wave marks a real shift: glass skin is no longer a 10-step project.
The 2026 routine is 4 barrier-first steps, and brands now label it that way on their own sites.
This post covers what the 4 steps are, which categories to spend on, and how to pick the one serum that earns its spot.

Glass skin routine 2026: why the 10-step stack collapsed
A 10-step routine made sense when every step was a treatment.
It stopped making sense when brands started folding three steps into one product.
The serum stick is the clearest case.
A serum, a moisturizer, and an SPF now come in one stick, applied in one pass.
When one product does the work of three, the remaining steps do not need a number system.
What replaced the stack is a short list ordered around the skin barrier: cleanse, tone, one targeted serum, moisturize.
Sunscreen folded into the last two steps rather than standing alone as its own ritual.
| Routine length | 4 steps (was 10) |
|---|---|
| The 4 steps | Cleanse, tone, serum, moisturizer |
| Key 2026 launches | Beauty of Joseon Hanbang Glass Serum Stick (SPF 50+), Dr. Jart+ 2026 glass-skin mask |
| Serum layering | 2–3 serums max per routine |
| Barrier keywords | Ceramides, propolis, panthenol |
The 4-step barrier-first routine, in order
Step 1 is a gentle cleanse.
Low pH cleansers remain the default; the goal is removing sunscreen and sebum without stripping the barrier.
Step 2 is a hydrating toner.
Applied to slightly damp skin, it works as the first hydration layer rather than an astringent.
Step 3 is one targeted serum.
One, chosen by concern — texture, tone, or firmness.
The 2026 protocol favors one serum used consistently over three layered ones, though layering up to three remains common for very dry skin.
Step 4 is a moisturizer that locks with barrier lipids.
Ceramide and propolis creams are the standard seal.
On mornings with sun exposure, an SPF step — or the new serum-stick format — goes on top.
What to buy — and what to skip
Spend on the four core categories: a low pH cleanser, a hydrating toner, one serum, and a ceramide cream.
These carry the routine, and the 2026 launches concentrated improvements here.
Skip the essence-by-essence collection.
Under a 4-step routine, a separate essence mostly duplicates the toner and serum steps.
Skip the 7-skin method as a daily habit too; it belongs on very dry nights, not every day.
Sheet masks are optional, not core.
The Dr.
Jart+ 2026 edition mask is marketed as a glass-skin booster for the seasonal transition, which makes it a reasonable occasional add-on — the kind of product that supports the routine rather than defines it.
How to pick the one serum
Check the ingredient list in this order.
First, hydration humectants: hyaluronic acid or glycerin as the base.
Second, the barrier actives.
Ceramides and propolis are the keywords overseas shoppers filter for, and brands now surface them on product pages.
Third, soothing agents.
Cica and panthenol calm redness while keeping the glow, which matters for reactive skin.
Fourth, texture match.
Dry skin takes richer, more emollient formulas; oily or combination skin takes gel or watery textures.
If breakouts are a concern, verify the product is labeled non-comedogenic before buying.
Niacinamide and peptides are the actives with the most current momentum for tone and firmness, and they layer well inside the one-serum slot.
Layering rules that still apply
Even a 4-step routine has ordering rules.
Apply from thinnest to thickest texture, letting each layer absorb before the next.
Two to three serums is the maximum if layering at all.
Past that, products pill and absorption drops.
Skip heavy slugging unless skin is genuinely dry.
On oilier skin, a light occlusive layer or a serum with squalane does the sealing job without congestion.
What the 2026 launches mean for buyers
The COSRX ‘Glass Skin Edit’ on its official site is the tell: when a brand curates a set under the trend name, the trend has become a product category.
That helps buyers.
Fewer steps means less guesswork, and brand-labeled kits signal which products the maker considers core.
The autumn timing also matters.
September launches are tuned to the summer-to-autumn transition, when barriers weaken.
Restocking the barrier step now is the practical move.

Quick tips before you rebuild your routine
- Keep the full routine to 4 steps: cleanse, tone, one serum, moisturize with ceramides.
- Cap serum layering at 2–3 products, and only for very dry skin.
- Check for ceramides, propolis, cica, or panthenol before buying a barrier product.
FAQ
Q. Can the 10-step routine still work?
It can, but it is no longer necessary. The same result now comes from 4 barrier-first steps, and 2026 products are formulated for that shorter sequence.
Q. Is the Beauty of Joseon Hanbang Glass Serum Stick a sunscreen?
It is a serum stick with SPF 50+, launched September 1, 2026 as the first glass-skin booster in stick form. Treat it as a serum-plus-sun hybrid for morning use.
Q. Which serum should a beginner buy first?
Pick one with hyaluronic acid or glycerin as the base, plus ceramides or propolis for the barrier, in a texture matched to skin type. One serum used daily beats three used occasionally.
The 4-step protocol is now the default, not the shortcut. Build around barrier health and let one serum do the targeted work.
