For these kinds of horizontal neck lines we often suggest hyaluronic acid fillers at our clinic, especially when the lines are well-defined and visible at rest. In many cases, a soft filler such as Belotero can be used to gently fill the creases and create a smoother appearance while maintaining a natural look. However, neck lines are often caused by a combination of factors, including skin thinning and collagen loss. If there is significant loss of skin elasticity, collagen-stimulating treatments may also be beneficial. Options such as collagen boosters can help improve skin quality over time by encouraging the body's natural collagen production. Radiofrequency (RF) treatments, such as Thermage, can also be effective for patients experiencing skin laxity and collagen depletion. Often, the most effective results come from combining filler treatment with collagen-stimulating procedures to address both the visible lines and the underlying skin quality.

We always recommend that patients first understand the main causes of their under-eye concerns, whether they are related to pigment, structural factors, skin thinness, or even fat protrusion under the eyes. Not all under-eye treatments serve the same purpose, so the best approach depends on the underlying cause. Collagen boosters can definitely help improve multiple concerns to some extent, especially skin quality and thinness. However, in cases where there is a structural hollow or sunken under-eye area, collagen boosters alone may not provide enough volume or support. There are also cases where under-eye fat causes irregular contours or puffiness, which may require a completely different approach. Rather than focusing on trends or a single “best” treatment, we believe it’s more important to identify the primary causes and tailor the treatment plan to each patient’s anatomy and goals.

It is understandable how frustrating PIH can be, especially after you’ve already gone through so many treatments. Post-inflammatory hyperpigmentation is unfortunately one of the more stubborn types of pigmentation because the skin in these areas tends to be thicker, slower to heal, and more prone to recurring inflammation. That said, PIH is generally not untreatable, but it tends to respond slowly and requires very targeted, consistent approaches over time. Q-switched lasers are quite versatile, but in cases like yours, results can sometimes be limited or inconsistent. You may benefit more from a more focused and controlled approach such as pico-toning (picosecond laser treatments), which targets pigment more precisely with less thermal damage to surrounding tissue. However, as mentioned before it typically requires multiple sessions spaced appropriately apart to allow the skin to heal in-between. Progress is usually gradual, but many patients do see clearer improvement over time when the protocol is consistent and properly tailored. It may also be worth reassessing inflammation triggers and ensuring strict pigment prevention (sun exposure, friction, secondary irritation), since PIH often persists when there is ongoing low-grade irritation. It’s understandable to feel discouraged, but there are still reasonable options to explore.

First of all, we’d recommend getting an assessment to determine the type of dark circles you have, because the treatment depends on the underlying cause. In cases where the under-eye skin is thin and the blood vessels show through, we often recommend collagen-boosting treatments rather than traditional fillers. For the delicate under-eye area, we prefer collagen boosters with very small particles to avoid lumps or swelling. In Korea, a commonly used brand for this purpose is Ultracol, which helps build up collagen and naturally thicken the skin, reducing the see-through effect and improving the overall under-eye appearance.

Based on the depth and severity of your acne scars, Potenza may help improve skin texture and stimulate collagen, but to see a significant change, you would likely need multiple sessions spread over several months or even years.For more effective results, we usually recommend subcision, which directly addresses the main cause of rolling or sunken scars by releasing the fibrous bands tethering the skin. Subcision can be combined with collagen-stimulating treatments for a more lifted and smoother appearance.
