No secret product list — six steps

Search 'K-pop idol glass skin routine' and most answers dodge the honest fact: there is no single confirmed product list behind it, according to Allure, Byrdie, and several K-beauty explainer sites — just six repeated steps. This log walks through each step in order, and where a documented Anua product like the Heartleaf 77 Toner or the PDRN Collagen Glow Facial Serum Spray can honestly slot in, without inventing a claim that isn't on Anua's own product pages.

The log

The six steps, logged

Sourced from Allure, Byrdie, iwaymagazine.com, tirabeauty.com, michelegreenmd.com, and asianbeautyessentials.com.

  • 1. Double cleanse — oil-based cleanser first, then a water-based cleanser.
  • 2. Hydrating toner, applied in 1-3 thin layers.
  • 3. Glow serum matched to one concern — niacinamide, vitamin C, hyaluronic acid, or centella, picked one at a time rather than stacked.
  • 4. Moisturizer.
  • 5. Daily SPF30+.
  • 6. Weekly exfoliation (1-2x) plus sheet masks (1-3x) — occasional, not daily.

Where Anua fits

Slotting in, honestly

Step 2 (hydrating toner) is where Anua Heartleaf 77 Toner slots in for readers who want the calming-toner version of this step — its documented 77% Houttuynia cordata content is Anua's own stated formula anchor. Readers chasing the glow-forward, milkier glass-skin read on the same step instead can use Anua's Rice 70 Glow Milky Toner as an alternate. Step 3 (glow serum) is where the PDRN Collagen Glow Facial Serum Spray can substitute for a mist-format serum layer — one option within the niacinamide/vitamin C/HA/centella family this step actually calls for, not a replacement for the whole step.

Method

Criteria for what we logged

How each product got placed into a step, not just named.

  • Only stepped a product in where its documented formula matches the step's actual function.
  • Kept every step's non-Anua options visible rather than only naming Anua.
  • Sourced the six-step structure from named outlets, not invented.
  • Distinguished 'glow' framing from 'calming' framing, since they're different formula goals.

FAQ

Common questions about this routine

As of 2026, this six-step structure is still the most consistently reported version of the routine.

  • Q: Do I need all six products daily? A: No — steps 1-5 are daily, step 6 (exfoliation and masks) is explicitly weekly or occasional.
  • Q: Can I use both Anua toners? A: You can, but pick by need — Heartleaf 77 for calming, Rice 70 Glow Milky for a glow-forward finish, not both for the same purpose.
  • Q: Is this routine safe for sensitive skin? A: The structure itself is gentle, but step 3's active choice (vitamin C vs. centella, for example) should match your actual tolerance.
  • Q: Is the PDRN spray required? A: No — it's one option for step 3's serum slot, not a mandatory addition to the six-step structure.
