This is a procedure note for Acne Scar Laser: Why do pigmentation and depressed scars require different treatments? at Beomgye(Opening Soon) KKEUT Korean Clinic.

Many people look into acne scar laser treatments due to marks remaining even after acne inflammation has subsided.



However, while acne scars may appear similar on the surface, they can actually be classified into two types with different characteristics.



One is a pigmented scar, which is red or brown, and the other is an indented scar, where the skin surface is sunken.







Pigmented scars are traces that occur when melanin pigment is excessively deposited after an inflammatory reaction.



On the other hand, indented scars are traces that occur when collagen tissue in the dermis is damaged due to inflammation, causing the skin to sink.



Since the causes differ, the treatment approach must also differ accordingly.



The treatment plan can be established differently depending on whether the scar is pigmented or indented.







For pigmented scars, it is important to stabilize the activity of melanocytes, which control melanin production, while for indented scars, methods that induce the creation of new collagen in the dermis are necessary.



One method that can address both these problems simultaneously is Potenza, an acne scar laser that utilizes a high-frequency device in the form of fine needles.



Potenza works by having micro-needles reach the dermis to create channels, and then high-frequency energy is emitted from the needle tips to promote collagen and elastin production.







Whereas previous fractional lasers used a method of micro-damaging the skin surface, Potenza approaches it by reducing surface burden while providing intensive stimulation to the dermis.



Dermal regeneration stimulation can help improve indented acne scars, and for pigmented scars, the energy action that calms sensitive melanocytes can have a positive effect.







Potenza treatment can be applied to improve acne scars, indented scars, enlarged pores, hyperpigmentation, and fine wrinkles.



It can also contribute to reducing acne recurrence by suppressing overly active sebaceous glands.







Potenza treatment is generally performed at intervals of 4 to 6 weeks, and for scar improvement, 3 to 5 sessions may be considered.



After anesthesia, the pain can vary from person to person but is controllable. Redness and pinpoint bleeding usually appear immediately after treatment and typically subside within 1 to 2 days.







For 1 to 2 days after the treatment, it is advisable to avoid activities that can induce heat in the body, such as saunas, strenuous exercise, and alcohol consumption. Additionally, special attention should be paid to moisturizing and sun protection.
