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
クレーター状のニキビ痕には、微細な針で肌表面に穴をあけ再生を促すダーマペンや、針先から高周波による熱エネルギーを照射するサーマニードルといった治療法があります。また、高周波を使用するポテンツァも、クレーターに用いられる治療法の1つです。ただし、くぼみが深い場合は、凹凸の原因となっている固くなった皮膚組織を切り離して皮膚表面を滑らかにするトライフィルやサブシジョンを選択すると良いでしょう。クリニックによっても取り扱いのある施術内容が異なるため、リサーチしてみてください。
Laser treatment for redness
If redness is caused by capillary dilation,Typical treatment with V-beamです。Vビームは、赤みのもととなっている血管内のヘモグロビンだけに反応します。そのため、痛みや周囲の皮膚へのダメージが少ないのが特徴。治療後は一時的な赤みや腫れ、内出血が生じることがありますが、数日から数週間で徐々に改善するケースがほとんどです。
他にも、負担を抑えながら肌の深部にアプローチして毛細血管を退縮させるロングパルスYAGレーザーなどもあります。担当医と相談した上で自分に合った治療を選択してください。
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
レーザー治療後は肌が敏感になっているため、適切なスキンケアと、生活する中でさまざまな配慮が必要です。まず、治療直後は患部を清潔に保ち、刺激をできるだけ避けるようにしましょう。また、紫外線対策も欠かせません。日焼け止めを塗り、直射日光を避けることを意識してみてください。
レーザー治療を受けた肌は乾燥しやすいため、保湿ケアを行うことも重要です。刺激の少ない化粧水や保湿クリームなどを使用し、患部を必要以上に触らないよう注意しながら保湿します。メイクは、医師の指示に従って再開するようにしましょう。
