This promotes more uniform light reflection, making the unevenness less noticeable.<\/p>\n<p><strong>STEP 2<\/strong><br \/>\n<img decoding=\"async\" src=\"https:\/\/ic-clinic-ueno.com\/wp-content\/uploads\/2026\/04\/treatment-step2.webp\" alt=\"STEP2: Releasing adherent scar tissue with subcision\" class=\"aligncenter\"><\/p>\n<h4 id=\"i-4\">Releasing Adherent Scar Tissue with Subcision<\/h4>\n<p>Abnormal scar tissue that has become fibrotic beneath the skin\u2014pulling the surface downward\u2014is cut and released using a specialized needle. This frees the base of the indentation, allowing the skin to rise.<\/p>\n<p><strong>STEP 3<\/strong><br \/>\n<img decoding=\"async\" src=\"https:\/\/ic-clinic-ueno.com\/wp-content\/uploads\/2026\/04\/treatment-step3.webp\" alt=\"STEP3: Shallower indentation and smoother skin\" class=\"aligncenter\"><\/p>\n<h4 id=\"i-5\">Shallower Indentation and Smoother Skin<\/h4>\n<p>Surface smoothing by the laser and deep release by subcision work together synergistically. As collagen regeneration progresses after treatment, further improvement in the indentation can be expected.<\/p>\n<h4 id=\"i-6\">OPTION: Hyaluronic Acid Injection<\/h4>\n<p>Following subcision, hyaluronic acid may be injected to help prevent re-adhesion of scar tissue. The hyaluronic acid acts as a spacer, supporting more consistent improvement of the indentation.<\/p>\n<h2 id=\"i-7\">Three Types of Acne Scar Craters<\/h2>\n<p>Crater scars fall into three main types, each of which responds best to different treatment approaches.

It may be particularly helpful for deep indentations and tethered craters that have shown limited improvement with Dermapen Microneedling or fractional laser. Results vary among individuals.<\/p>\n<h3 id=\"i-32\">How many treatment sessions are typically needed?<\/h3>\n<p>This depends on the severity of your condition, but a general guideline is 1\u20133 sessions per area. Treatment intervals are typically 1\u20133 months apart, with a total treatment period of approximately 3\u201312 months. A more specific recommendation will be made during your consultation.<\/p>\n<h3 id=\"i-33\">What is the expected downtime?<\/h3>\n<p>Downtime varies depending on the treatment area and the individual, but is generally around 1\u201310 days. Redness, swelling, and scabbing may occur after treatment, but these gradually subside. Bruising may also appear in some cases and typically fades within 1\u20132 weeks.<\/p>\n<h3 id=\"i-34\">Is the treatment painful?<\/h3>\n<p>Local anesthesia is used to minimize discomfort during the procedure. Some mild pain or discomfort may be felt once the anesthesia wears off, which can typically be managed with over-the-counter pain relief.<\/p>\n<h3 id=\"i-35\">Dermapen Microneedling didn\u2019t work for me \u2014 could this treatment help?<\/h3>\n<p>Dermapen Microneedling primarily targets the superficial layers of the skin, which means it may provide limited improvement for deep craters or tethered scars caused by subcutaneous adhesions. Since CO2 Laser + Subcision can reach deeper layers, it may offer improvement for craters that did not respond to Dermapen. Results vary among individuals.<\/p>\n<h3 id=\"i-36\">What are the possible side effects and risks?<\/h3>\n<p>Possible side effects include bruising, swelling, scabbing, redness (lasting several weeks to several months), temporary post-inflammatory hyperpigmentation, and firmness in the treated area. Please note that not all craters will fully disappear, and the degree of improvement varies among individuals. Full details will be explained during your consultation.<\/p>\n<h3 id=\"i-37\">Is there a minimum age requirement for treatment?<\/h3>\n<p>Treatment is available for minors with parental or guardian consent. We generally recommend waiting until active acne has fully settled before undergoing crater scar treatment. Please feel free to discuss this during your consultation.<\/p>\n<div class=\"web-btn__box\">\n<div class=\"q_button_wrap\"><a class=\"q_custom_button q_custom_button1\" href=\"https:\/\/ic-clinic.com\/reservation\/ueno\/\">Book Online Now<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\ud83d\udcac Crater scar treatment is currently available only at IC Clinic Shinjuku (Saturdays).
