Types and characteristics of acne scars
Before mentioning treatment, we will take a closer look at acne scars by type. There are three main types of acne scars: pigmentation, cratering, and redness. Let's start by checking out the characteristics of each.
■Pigmentation type acne scars
The pigmentation type of acne scarring (postinflammatory hyperpigmentation) is caused by brown or black pigment that remains after the inflammation has subsided. This is,Caused by excessive production of melanin pigmentThe skin is not able to turnover. After inflammation caused by acne occurs, the turnover of the skin is disrupted, making it difficult for the body to expel the large amount of melanin pigment that has been produced. As a result, pigmentation remains on the skin surface.
■Crater-like acne scars
Cratering acne scars (depressed scars) are,Indentations resulting from damage to the dermal layer of the skin due to inflammationIt is. This is because the damaged dermal layer needs a lot of time to be renewed,Difficult to heal spontaneouslyIn many cases, this tends to require specialized treatment at a clinic.
■Reddish type acne scars
Acne scars with redness (post-inflammatory erythema) are caused by inflammation that remains inside the skin or after the skin's inflammatory response has subsided.It is caused by capillaries that remain dilatedThe redness will also be more malignant if the skin is thinner due to acne damage. Sometimes it will disappear spontaneously, but sometimes it will remain after six months or more and become a skin problem as acne scars.
Recommended laser treatment for different types of acne scars
Different types of acne scars require different suitable laser treatments. Here are some treatments that match each one.
■Laser treatment suitable for pigmentation type
Those suffering from pigmentation-type acne scars often use laser toning. A laser that works deep into the skin at low power is irradiated,Decomposes melanin pigmentThe laser beam is instantaneous, which reduces damage to the skin and reduces the risk of inflammation. The instantaneous laser irradiation reduces damage to the skin, which reduces the risk of inflammation and improves hyperpigmentation. This treatment method breaks down melanin pigments within the skin,Another feature of this product is that it does not easily form scabs.The procedure is popular among busy women and first-timers to cosmetic procedures because there is very little downtime and makeup can be applied immediately after the procedure. The fact that there is almost no downtime and makeup can be applied immediately after the procedure makes it popular with busy women and those new to cosmetic medicine.
■Effective laser treatment for cratering acne scars
Treatment methods for cratering acne scars include the Dermapen, which uses a fine needle to pierce the skin's surface to promote regeneration, and the Thermaneedle, which uses high-frequency heat energy emitted from the tip of the needle. Potenza, which uses radiofrequency waves, is another treatment used to treat craters. However, if the indentations are deep, it is better to choose Trifil or Subsicion, which smooth the skin surface by cutting away the hardened skin tissue that causes the irregularities. Research the different procedures that are handled by different clinics.
Laser treatment for redness
If redness is caused by capillary dilation,Typical treatment with V-beamThe V-beam reacts only to hemoglobin in blood vessels, which is the source of redness. Therefore, there is less pain and damage to the surrounding skin. Temporary redness, swelling, and internal bleeding may occur after treatment, but most cases gradually improve within a few days to a few weeks.
Other options include the long pulsed YAG laser, which approaches deeper into the skin to regress capillaries while reducing the burden. Please select the treatment that is right for you after consulting with your doctor.
The expected results and number of times for laser treatment.
A wide range of laser treatments are used by many clinics as useful in improving acne scars. Many physicians support laser treatment because of its balance of immediate and long-lasting effects. The following is a summary of the effects that can be expected from laser acne scar treatment and the approximate number of times and frequency of treatments.
■Immediate and long-lasting
Laser therapy is a treatment for the improvement of acne scars.Effective treatment with immediate and lasting resultsThe first is the "laser". Some laser equipment combines the performance of the laser with the ability to improve skin texture and tone after treatment. In addition, the thermal action of the laser stimulates collagen production, which may improve skin texture over time. However, since the treatment method matched to the type and severity of acne scars will vary, consultation with a specialist is the key. With any of the treatments, you will be able to experience more reliable results by continuing regular treatment.
■Recommended number of treatments and intervals
Multiple treatments are required to improve acne scars with laser therapy. The specific number of sessions depends on the type and depth of the acne scars, so it is difficult to generalize,5-8 times for pigmentation type、At least 5 times for reddish typeThe standard treatment interval is 2 to 4 weeks. The treatment interval may vary depending on the indicated procedure, but a short interval of 2 to 4 weeks is recommended. This will help the skin to recover and promote collagen production, leading to healthy skin. However, since there are individual differences, it is important to consult with a physician to determine the number of treatments and intervals that are appropriate for each individual.
■ Post-treatment skin care and precautions
Since the skin is more sensitive after laser treatment, proper skin care and various considerations in daily living are necessary. First, immediately after treatment, keep the affected area clean and avoid irritation as much as possible. UV protection is also essential. Try to apply sunscreen and avoid direct sunlight.
Since laser-treated skin tends to dry out easily, it is also important to moisturize the skin. Use a non-irritating lotion or moisturizing cream, and moisturize while being careful not to touch the affected area more than necessary. Makeup should be resumed according to the doctor's instructions.
