Causes of Recurring Acne and Dermatology Laser Treatment Methods
Learn the primary causes of recurring acne, how scarring develops, and effective dermatological laser treatments like Agnes and fractional resurfacing at WJ Wonjin.


Hello, this is WJ Wonjin Plastic Surgery & Dermatology :D
While acne is widely known to occur frequently during adolescence,
it also often recurs in adulthood.
Acne tends to recur chronically,
and leaving it untreated or extracting it improperly can lead to scarring.
Therefore, once acne appears, receiving proper treatment
and professional care is essential.

Q. What is acne?
A. Acne is a condition triggered as hormone secretion becomes active.
Stimulated by hormones, the sebaceous glands mature,
and the increased sebum cannot be discharged outward properly,
accumulating in the pores and sebaceous glands to cause inflammation.
If acne is not treated in its early stages,
the risk of erythema, hyperpigmentation, and scarring significantly increases.
In particular, pitted or atrophic scars are difficult to treat
and do not easily disappear once formed,
requiring customized therapeutic approaches based on an accurate diagnosis to improve.

STEP 03. Targeted Acne Treatment
Fast and accurate acne relief via tailored therapy addressing the root causes
STEP 04. Pigmentation Treatment
Relief of red marks, post-inflammatory pigmentation, and scars caused by acne

Q. What are the causes of acne?
A. Proliferation of acne bacteria, excessive sebum secretion,
inflammatory reactions, and a thickening stratum corneum (dead skin cell layer).
<Acne-Aggravating Factors>
Lack of sleep, improper facial cleansing techniques,
incorrect extraction habits (squeezing with hands, excessive force),
use of excessively oily cosmetics, irregular lifestyle habits,
physical and mental stress, and excessive alcohol consumption and smoking.
Q. Why (and how) does acne develop?
A. It is caused by acne bacteria living
within the impurities and sebum trapped deep inside the skin.
If pores are not thoroughly cleansed,
sebum accumulates and builds up,
causing pores to enlarge and bacteria to multiply.
01. Clogged Pores
Pores become clogged, and undrained sebum congeals.
02. Proliferation of Acne Bacteria
Sebum plugs develop into blemishes, and bacteria proliferate.
03. Development of Inflammation
Acne bacteria multiply further, leading to active inflammation.

Q. What are the acne treatment methods at WJ Wonjin Dermatology?
Allegro Laser
Interacts directly with the sebaceous glands responsible for acne,
reducing excessive sebum secretion and preventing recurrence.
By stimulating collagen remodeling, it delivers benefits such as
pore tightening, elasticity improvement, and skin rejuvenation.
Agnes
Directly destroys the sebaceous glands that cause acne
using specialized micro-insulated needles.
It provides a fundamental solution for chronic, recurring acne
and is also utilized to treat syringoma, periorbital fine lines,
and stubborn blackheads.
Affinite
Delivers active ingredients deep into the pores
via a high-velocity micro-jet stream
to eliminate waste and reduce inflammation.
By inducing dermal remodeling in damaged or aging skin,
it helps achieve skin regeneration, enhanced elasticity,
reduction of fine lines, and minimized pores.

Q. What causes acne scars?
Post-inflammatory hyperpigmentation & post-acne erythema
caused by repetitive inflammatory acne
Secondary infections resulting from improper extraction
Scarring caused by forcefully popping pimples
Pore enlargement & recurring acne caused by
improper skincare and heavy cosmetic usage
When acne inflammation intensifies,
skin fibers clump and tangle together,
creating tissue adhesions. When the skin surface
contracts and hardens in a depressed state,
it leaves behind uneven, pitted acne scars.

Q. What are the acne marks and scar treatments at WJ Wonjin Dermatology?
Intracel
Delivers radiofrequency (RF) energy directly into the dermis
through 49 micro-needles.
It promotes collagen regeneration, treating acne scars, shrinking pores,
brightening skin tone, and improving dermal elasticity.
Legato
Delivers plasma energy to the skin surface
to create micro-channels.
After applying skin-regenerating therapeutic solutions,
ultrasound technology drives the active ingredients deep into the tissue,
stimulating collagen remodeling to effectively treat acne scars,
stretch marks, and fine wrinkles.
MCL30 Fractional Laser
Emits micro-laser beams onto depressed or elevated scar tissue.
Inducing regenerative responses from the epidermis down to the dermis,
it allows for highly precise resurfacing.
It provides comprehensive improvements for acne scars, traumatic scars,
enlarged pores, fine lines, and overall anti-aging.

Frequently Asked Questions
What are the primary causes of acne?
Excess sebum production, clogged pores, and the proliferation of acne bacteria are the main causes. When sebum fails to be discharged normally and builds up inside pores, bacteria multiply and trigger an inflammatory response. In addition, sleep deprivation, stress, improper extraction, and the use of heavy, oil-rich cosmetics are key factors that exacerbate acne.
Why do acne scars develop?
Acne scars are caused by severe inflammation and improper extraction techniques. Forcefully squeezing blemishes can cause secondary infections or abnormal clumping and adhesion of skin fibers, resulting in tissue contracting downward and hardening. As inflammatory breakouts recur, they can leave behind hyperpigmentation, persistent erythema, and uneven, pitted permanent scars.
Which laser treatments are effective for chronic, recurring acne?
Agnes and Allegro lasers are particularly effective. Agnes uses micro-insulated needles to selectively destroy the overactive sebaceous glands responsible for breakouts, fundamentally preventing recurrence. The Allegro laser targets sebaceous activity to decrease excess oil while stimulating collagen remodeling to tighten pores and regenerate tissue.
How are pitted acne scars treated?
Pitted acne scars are addressed using skin-resurfacing and remodeling devices such as Intracel, Legato, and the MCL30 Fractional Laser. By delivering micro-needles, plasma energy, or fractional laser beams into the epidermal and dermal layers, these treatments create micro-wounds and enhance active ingredient penetration. This triggers deep collagen remodeling, effectively smoothing pitted scars and tightening enlarged pores.
