There may be so many causes of enlarged pore (or depression of skin around pore). But clinically 3 kinds of factors may be important. That is increase of sebum production, decrease of skin elasticity around pore and increase of hair follicle volume including thick hair.
Other related factors are acne, sex hormone, comedon inducing chemicals (cosmetics, etc.) washing habits, chronic exposure to UV rays, aging, genetic factors
According to the causes, various treatments including PDT (photodynamic therapy), microneedle RF (radiofrequency), hair removal, CO2 fractional laser, skin botox, IPL may be needed

- 1Treatment for sebum & elasticity
-
According to over 10 years of experiences of JD clinic, treatment for increased sebum production, enlarged pore locally and effectively is PDT (photodymic therapy) and microneedle RF(radiofrequency). Other treatments could shows systemic side effects (for example, isotretinoin) or short duration of effect (for example, lasers).
Microneedle RF shows synergistic effect for pore size reduction when combined with PDT and increase skin elasticity.
Combination treatment of microneedle RF and PDT is also useful and powerful option for increased sebum production, white head, black head, inflammatory acne and skin rejuvenation.
- 1PDT+microneedle RF
-
※PDT(photodynamic therapy)
Mechanism & Principle
PDT needs photosensitizer, light source, oxygen. Photosensitizer(ALA) is activeated by visible lights and reactive oxygen is made. This induce apoptosis and necrosis of sebaceous gland cells.
PDT woks effectively in 4 kinds of pathophysiologies
• increase of sebum production
• proliferation of P. acnes
• inflammation
• abnormal keratinization
Indication
• Excessive sebum production
• Enlarged pore
• Hot flushing due to mild inflammatory acne
• Moderate~severe inflammatory acne
• Acne of children and pregnanant woman
• Skin rejuvenation (skin texture, elasticity)
Contraindications
• Porphyria
• Systemic lupus erythematosus, SLE
• Photosensitive skin disorders
• Allergy to ALA
Time of procedures
• 2~3 hours (PDT only)
• 3~5 hours (PDT+microneedle RF)
Processes of procedures
• Extraction of comedons (meticulous extraction is very important)
• Softening of comedons and skin
• BHA application
• Aquapeeling
• Laser extraction( if needed)
• Numbing cream about 30 min
• Microneedle RF
• Application of ALA
• IPL
• Injection for inflammation reduction
• Irradiationf of blue and red light
• Soothing management
Interval of procedures
• 3~6 months (PDT only)
• 6~12 months(PDT+microneedle RF)
Effects
• Reduction of white head, black head, inflammatory acne
• Pore size reduction
• Sebum production decrease
• Skin texture and elasticity improvement
Progress and possible side effects after procedures
• Erythema, edema, burning sensation, pruritis
• Folliculitis
• Desquamation
• Hyperpigmentation
• Hypopigmentation
Cautions after procedure
• Washing face after procedure due to removal of ALA
• Minimize sun exposure for 48 hours for prevention of hyperpigmentation due to ALA. This hyperpigmentation disappears spontaneously with time. But it may be stressful until that disappears
• Some patients shows severe desquamation of the treatment areas. If it occurs, do not detach intentionally it but manage to be taken off spontaneously through 7 days.
※Microneedle Radiofrequency (DeAge, Scarlet)
Features and principal
Microneedle radiofrequency treatment works by precisely delivering radiofrequency energy to the lower layers of the dermis using microneedles. This treatments stimulate collagen production and reshape skin elastic fibers gradually and continuously, restoring skin firmness and tone. It is also used effectively for the treatment of moderate to severe inflammatory acne vulgaris. It is suggested that the mechanism of action is mainly a reduction of sebaceous gland activity and the promotion of dermal architecture remodeling by thermal stimulation.
Effect
• Acne (recommend combination treatment with PDT)
• Scars (burn, postoperation etc.)
• Striae
• Skin lifting
• Elasticity
• Fine wrinkle
• Whitening
• Enlarged pore
• Skin texture
Time of procedure
• Anesthetic cream 30 min
• Procedure 20~30 min
• Post care 30 min
Pain
• none~mild
Progress and possible side effects
• Hot flushing for about 3 hours after the procedure
• Edema for about 3 hours (mild)
• Desquamation for about 7 days (mild)
• Dryness at the procedure sites for about 1 month
• Pruritis(itching) for about 14 days (mild)
• Allergy
• Postinflammatory hyperpigmentation (PIH)
• Infection
• Contact dermatitis
• Folliculitis
• The complete effect is observed around 8-12 weeks after treatment
Cautions before the procedure
• Avoid the medications and creams that affect skin condition profoundly for at least 1 month, for example isotretinoin
Cautions after the procedure
• Cold massage after the procedure for about 2 days for the fast recovery
• Moisturizing cream and sunblock
• Avoid rubbing the treatment area excessively for about 7 days
• Avoid irritating cosmetics and non-prescription cream for about 1 month
• In case of suspected infection or allergy, contact the clinic
- 1CO2 Fractional Laser
-
CO2 fractional laser usually offers a high level of satisfaction if applied to address individual needs of the patient.
The highest possible energy should be used for the improvement of pores, elasticity, wrinkles, skin texture within the tolerance level.
Under the intensified treatment condition, the procedure will take 20+ minutes and after care over 30 minutes.
The penetration depth of CO2 fraction laser is 1mm, so in order to make improvement in deep tissue area, Microneedle Radiofrequency (DeAge, Scarlet) is recommended as an additional measure.

-
CROSS(Chemical Reconstruction of Skin Scars)
Features
Application of TCA to the skin causes precipitation of proteins and coagulative necrosis of cells in the epidermis and necrosis of collagen in the papillary to upper reticular dermis. Dermal collagen remodeling after chemical peel may continue for several months. There are reorganization in dermal structural elements and an increase in dermal volume as a result of an increase in collagen content, glycosaminoglycan, and elastin.
Indications
• Enlarged pore
• Depressed scar(acne, postoperation, chicken pox, etc.)
Time
• Anesthesia: 30 min • Procedure :10~60min
Pain
• mild~moderate
No. of treatments
• Generally 3~6 courses
Interval
• 1~3moths
Progress and possible complications
• scabs for about 5~10 days
• mild erythema (if it occurs, 2–8 weeks)
• postinflammatory hyperpigmentation (if it occurs, 1~2month)
• focal skin infections (mild pustular eruptions)
• gradual increase in dermal volume through 6 months
• dryness and mild pruritis of face and resolve with time
Cautions after procedure
• apply only moisturizing cream until scabs fall off (do not apply sunblock when there are scabs)
• after detachment of scabs, apply moisturizing cream and sunblock everyday
• if you want to apply whitening material on the face or take oral medication, consult a doctor
• avoid irritating cosmetics and non-prescription cream for about 1 month

- 4Skin Botox (Botulinum Toxin)
-
The basic function of Botulinum toxin is weakening function of muscles and sweat glands.
Skin Botox (Dermatoxin) is a procedure in which Botox is injected intradermally, not in muscles.
The Effects of Skin Botox include
Lifting
Pores reduction
Pimple treatment
Sebum reduction
Sweat secretion reduction
Wrinkle lifting
Improved facial flushing
The immediate tightening and shining effect will take place after the procedure and wrinkles and pores will disappear in 15-30 days.
Usually 50 units are used per treatment for full effect.
- 5HIFU (Ultraformer)
-
Ultraformer leaves no damage on the skin by utilizing ultrasonic effect for lifting, improving skin elasticity, pore minimizing and etc.
The procedures with be carried out in a various depths: 4.5mm, 3mm, 1.5mm.
With proper intensity and techniques, the effect of treatment is almost immediate.
- 6Other Treatments
-
Most procedures using laser, high-frequency, ultrasonic instruments have effect on achieving resilient skin elasticity and minimize pores.
Therefore, it is important to determine which equipment is best for the required procedures as well as the technique of the doctor. The effect of laser treatments of the sedum over-secretion is limited and temporary.
