K-BEAUTY JOURNAL / NEW BRAND DISCOVERY
K-Beauty Skin Cycling, Simplified
How to rotate AHA/BHA/PHA, retinol and centella for smoother-looking skin—with fresh finds from SOME BY MI, SKIN1004 and SUNGBOON EDITOR.
A thoughtful K-beauty routine gives every active a job, every recovery night some space, and every morning a protection step. Here is a flexible four-night rhythm you can actually repeat.
The rule: choose one lead active, pair it with comfort, and let tomorrow’s routine do a different job.
THE CONCEPT
Give each night one clear job
Skin cycling is less about following a perfect calendar and more about spacing out your strongest steps. The classic rhythm is simple: exfoliation, retinoid, recovery, recovery. K-beauty makes the idea feel especially natural because hydration and barrier support are not afterthoughts—they are part of the routine.
Exfoliate
Use one AHA/BHA/PHA product to refresh the feel of skin and support a smoother-looking surface.
Retinoid
Choose one retinol-led treatment. Keep the rest of the routine calm and uncomplicated.
Recover
Bring in centella, ceramides, panthenol and moisturizer to restore comfort and hydration.
Recover again
Repeat your simplest comfort routine—or stay here longer if your skin needs it.
Beginner move: If you have never used acids or retinol, run recovery nights first. Add only one active night when your skin feels comfortable and predictable.
THE CALM-CLEAR RULES
How to make active skincare feel considered
A polished routine is not the one with the longest ingredient list. It is the one where you can tell what each product is doing—and where your skin has room to respond.
FEATURED BRANDS
Three under-highlighted brands, six useful roles
These are new-to-the-Journal catalog finds from SOME BY MI, SKIN1004 and SUNGBOON EDITOR. Together, they create a complete conversation around texture, pores, radiance, hydration and barrier support—without asking you to use everything in one routine.
SOME BY MI / NIGHT 01
SomeByMi AHA-BHA-PHA 30DAYS MIRACLE TONER 150ml
The acid-led toner for the first night of the cycle. Use it as a focused AHA-BHA-PHA step, not as an invitation to add three more exfoliants.
Lead exfoliation: After cleansing, the brand directs you to saturate a cotton pad, wipe gently along the skin texture, and pat. No scrubbing.

SOME BY MI / NIGHT 02
SomeByMi Retinol Intense Reactivating Serum 30ml
A retinol-led serum for a renewal-focused evening. Keep the rest of this night deliberately quiet so you can learn how your skin responds.
Lead retinoid: Start slowly and follow the package directions. Keep it separate from the acid night, especially when you are new to retinol.

SUNGBOON EDITOR / TEXTURE
SUNGBOON EDITOR Green Tomato Pore Boosting Deep Shot Ampoule 30ml
A Green Tomato line ampoule for a smoother-looking, more refined finish. Give it a clean, active-free slot instead of stacking it on top of every treatment.
Pore-focused support: Use as your targeted texture layer on a comfortable morning or recovery night; patch test and avoid overworking the skin.

SKIN1004 / RECOVERY
Skin1004 Madagascar Centella Probio-Cica Intensive Ampoule 30ml
Fermented Centella and ceramides make this the comfort anchor: a milky, silky ampoule that brings hydration and barrier support back into the rotation.
Barrier comfort: The brand’s directions are simple: apply an appropriate amount evenly, then pat to help it absorb.

SUNGBOON EDITOR / RECOVERY
SUNGBOON EDITOR Deep Collagen Barrier Serum Mist 95ml
A deep-collagen barrier serum mist for the moments when your skin wants water, slip, and a softer landing before cream.
Hydration prep: Mist lightly after cleansing or between steps. Choose this or another hydrating layer; more layers do not automatically mean more comfort.

SKIN1004 / EVERY MORNING
Skin1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum 100ml
A serum-like sunscreen with a fresh, dewy finish. This is the morning step that makes the rest of the routine worth protecting.
Daily protection: Use as the final step of basic morning skincare on exposed areas, following the current product label and local sun-safety guidance.
Shop this product ↗THE FOUR-NIGHT ROTATION
Your K-beauty skin cycling routine
Use the sequence as a starting point, not a rulebook. If your skin is dry, reactive, peeling or already overloaded, pause the active nights and stay with the recovery column.
Night 01 / lead active
Exfoliation night
Cleanse, apply the SOME BY MI AHA-BHA-PHA toner as directed, then finish with the SKIN1004 Probio-Cica Intensive Ampoule and your moisturizer.
Night 02 / lead active
Retinol night
Cleanse and let skin dry. Apply SOME BY MI Retinol Intense Reactivating Serum according to the label, then use moisturizer. Do not add the acid toner here.
Night 03 / recovery
Hydrate and settle
Cleanse, mist with SUNGBOON EDITOR Deep Collagen Barrier Serum Mist, then pat in SKIN1004 Probio-Cica Intensive Ampoule before cream.
Night 04 / recovery
Keep it beautifully simple
Repeat the recovery routine or reduce it to the layers your skin enjoys. If you want a pore-focused moment, test the SUNGBOON EDITOR Green Tomato ampoule only when your skin is calm.
| When | Order | What to remember |
|---|---|---|
| Every morning | Rinse or cleanse → optional comfort layer → SKIN1004 Hyalu-Cica Water-Fit Sun Serum | Make sun protection the final step of basic skincare. Follow the current package directions. |
| Night 01 | SOME BY MI AHA-BHA-PHA toner → recovery layer → moisturizer | One exfoliant is enough. Avoid rubbing or adding another acid product. |
| Night 02 | SOME BY MI Retinol serum → moisturizer | Keep this night separate from acids. Start slowly and adjust to your skin. |
| Nights 03–04 | SUNGBOON mist and/or SKIN1004 Probio-Cica → moisturizer | Recovery is not a skipped step—it is the part that keeps the routine repeatable. |
APPLICATION NOTES
How to apply K-beauty actives without overdoing it
The difference between a thoughtful routine and a crowded one is often pressure, timing and restraint. Apply each layer gently, allow it to settle, and give your skin time to tell you what it likes.
Swipe, do not scrub
With the SOME BY MI toner, saturate a cotton pad and glide lightly along the skin’s texture. Pat in the remaining product.
Keep the night quiet
Use the retinol serum as directed on clean, dry skin. If you are new to retinol, begin with one night per cycle—or less.
Layer for comfort
Mist first if desired, then apply the SKIN1004 ampoule and finish with moisturizer. Stop at the point your skin feels cushioned.
Choose a calm slot
Use the SUNGBOON EDITOR Green Tomato ampoule on an active-free morning or recovery night, not as a reason to stack treatments.
Make it the last AM step
Apply the SKIN1004 sun serum evenly to exposed areas at the end of basic morning skincare, following the label.
Listen early
Patch test new products. If your skin burns, swells, cracks or keeps reacting, stop the active and ask a qualified healthcare professional for guidance.
Do not copy a routine just because it looks good on paper. Acid toner plus retinol plus an additional peel in the same session is not a more advanced routine—it is a harder one to read and a harder one for your skin to enjoy.

QUICK ANSWERS
K-beauty skin cycling FAQ
Is skin cycling a fixed four-night schedule?
No. Four nights is a useful starting framework. If your skin needs more recovery, extend the recovery phase and restart when it feels comfortable.
Can I use the SOME BY MI acid toner and retinol together?
Keep them on separate nights, especially while starting. The point of this routine is to give each active its own clear role.
Where does SKIN1004 fit?
SKIN1004 is the recovery and protection anchor here: Probio-Cica Intensive Ampoule for comfort and the Hyalu-Cica Water-Fit Sun Serum for the final morning step.
Where does SUNGBOON EDITOR fit?
Use the Green Tomato ampoule as a focused pore-and-texture layer when skin is calm, and the Deep Collagen Barrier Serum Mist when you want a hydration-first reset.
Do I need all six featured products?
No. Start with one lead active, one recovery layer and a morning sunscreen. Add a second product only when the first routine feels easy to repeat.
When should I avoid active skincare?
Do not apply actives to wounded or strongly irritated skin. If you are pregnant, breastfeeding, managing a skin condition or using prescription treatment, ask a qualified clinician before adding a retinoid.
Build a routine with rhythm, not pressure. Start with one lead active, give it a recovery partner, and keep your morning protection step beautifully consistent.
