Acne All-in-One · Mellow Dermatology (Yeongdeungpo)
Recurring acne,
why does it keep coming back?
Even the same acne has different causes for different people. We diagnose sebum, inflammation, pigmentation, and scarring stage by stage, and combine multiple devices on a 1:1 basis — this is Mellow Dermatology's Acne All-in-One program.
Why All-in-One
Acne is not caused
by just one thing
Sebum, inflammation, pigmentation, and scarring are layered and intertwined, so a single treatment alone easily lets it return. That is why the 'layers' of causes must be approached separately.

Cause 01 · Sebum
Excess sebum production
When the sebaceous glands become overactive, pores clog easily and acne keeps recurring, shifting from spot to spot.

Cause 02 · Inflammation
Red, suppurative acne
When bacteria and inflammation build up in clogged pores, the skin swells red, spreads into suppurative acne, and becomes painful.

Cause 03 · Pigment & Marks
Brown pigment & red marks
Even after inflammation subsides, brown pigmentation and red marks linger for a long time, leaving the skin tone dull.

Cause 04 · Scars
Depressed scars & enlarged pores
Repeated inflammation damages the dermis, leaving depressed scars and enlarged pores that do not recover well even over time.
4-Step Protocol
In the order of the causes, in four steps
Sebaceous gland control → inflammation control → mark improvement → skin regeneration. Rather than repeating the same device, this is a layered custom protocol that combines the steps to suit your skin's condition on the day.
Sebaceous gland control
Extraction and scaling cleanse the pores, and Gold PTT shrinks overactive sebaceous glands to reduce acne's starting point.
Inflammation control
Vascular and inflammation lasers calm red, swollen inflammatory acne and redness, settling the spread.
Mark improvement
Pigment lasers gently fade brown pigmentation and red marks, evening out the skin tone.
Skin regeneration
Radiofrequency and fractional treatments improve scars and pores, while hydration and regenerative injections restore stimulated skin.
Devices
We combine the right devices
to match each cause
Each device targets a different cause and works on a different principle. Only by understanding what each device does best can we design the combination that is right for you.

Gold PTT · Photo Thermal
Gold PTT
Step 1 · Sebaceous gland controlNano-gold particles are infused into the pores and then heated with a laser to selectively shrink only the sebaceous glands. The focus is on fundamentally reducing the recurrence of acne caused by excess sebum.

Clarity II · 1064nm Long-pulse
Clarity II
Step 2 · Inflammation & redness calmingThe 1064nm long-pulse eases vascular redness and calms inflammatory acne. It effectively suppresses sebum production to soothe red, sensitive skin.

Hollywood Spectra · Q-switched Nd:YAG
Hollywood Spectra
Step 3 · Pigment & marksThe Q-switched Nd:YAG wavelength eases brown pigmentation and red marks, shrinks pores, and smooths shallow scar texture. With little downtime, it is used frequently.

Pico Plus · Picosecond
Pico Plus
Step 3 · Pigment & skin textureShort picosecond pulses break brown pigment into fine particles to even out the skin tone. Switching to fractional mode broadens its scope to improving skin texture and shallow scars.

Secret · Microneedle RF
Secret RF
Step 4 · Scars & poresMicroneedles deliver radiofrequency energy into the dermis to stimulate collagen regeneration. It tightens pores and gradually fills in depressed acne scars.

Potenza · Microneedle RF
Potenza
Step 4 · Acne & scarsA microneedle RF that delivers radiofrequency directly into the dermis through fine needles. With insulated and non-insulated needles and dual frequencies, it targets the sebaceous glands and inflammation of active acne, while also improving enlarged pores and depressed scars through collagen regeneration.

Lotus III · Erbium Fractional
Lotus III
Step 4 · Regeneration & scarsThe erbium fractional laser precisely removes the epidermal layer to induce dermal regeneration. It is used in the finishing stage to finely refine scars and rough skin texture.

Dermashine · Water Shine Infusion
Dermashine
Step 4 · Calming & regenerationIt evenly injects moisture, hyaluronic acid, and growth factors to calm the skin after treatment and support regeneration. It backs up the recovery of acne-prone skin with a weakened barrier.

Same Acne, Different Skin
Same acne,
a different plan for each type
Priorities differ depending on the type of acne. Based on what stands out most as your concern right now, we design the starting step and device combination differently.
Bumpy · sebum acne
Caused by clogged pores and excess sebum. Designed around extraction, scaling, and sebaceous gland control.
Red · suppurative acne
A type where inflammation and redness stand out. We focus on calming the redness with inflammation-soothing lasers.
Acne marks · scars
The concern is the pigmentation and depressions left after acne subsides. We refine tone and texture with pigment lasers and regenerative treatments.

Expert Care
It is the 'diagnosis',
not the device, that makes the result
Dr. Kwon Hyung-il, Medical Director · Dermatology Specialist
Many people come in exhausted by long-standing acne, asking for 'any treatment, as strong as possible.' But on a close examination of the skin, what is needed now is often not strong stimulation but the right order for the cause.
Accurate diagnosis and session-by-session planning come from the experience of a seasoned specialist. When the cause is read and the steps are fine-tuned, even the same device leads to safer and better results.
★ The Mellow Acne All-in-One principles
- A 1:1 custom protocol designed after diagnosis by cause and stage
- Custom combinations for each session, without repeating the same device
- Minimized burden on the skin · a step-by-step approach in the order of the causes
Before & After Care
Before and after treatment, just a few things
can change your recovery
After acne treatment, temporary redness or dryness may occur. If you get an accurate diagnosis before treatment, then afterward avoid UV exposure, refrain from washing your face or using cosmetics right away, and pay attention to moisturizing — you can reduce reactions and maintain the results for longer.
