Shinchon Station Dermatology: Fraxel Side Effects You Must Know Before Getting It image 1

Hello.

This is Kim Jang-ju from Shinchon Station Dermatology.

After acne has calmed down to some extent, there is something that starts to stand out even more.

That is acne scar hyperpigmentation.

Even if the breakouts seem to have disappeared on the surface, many people find that their skin does not look clear because of the red or brown marks left behind.

That is why many people end up wondering, “Isn’t there a way to get rid of this quickly?”

When searching online, one of the treatments most often mentioned for scar treatment is Fraxel.

At the same time, concerns about Fraxel side effects also often come along with it.

In actual consultations at Shinchon Station Dermatology, there are quite a few people who ask about side effects before they ask about effectiveness.

So today, from how Fraxel works to the parts you should be careful about,

and even alternatives that can reduce the burden, I’ll go through them one by one.

━━━━━━━━━━━━━━━━━━ 🔬 Fraxel: how does it work? ━━━━━━━━━━━━━━━━━━

Fraxel generally refers to a fractional laser treatment, most commonly represented by CO2 Fraxel.

It is widely used to improve indented acne scars and rough skin texture caused by acne.

The principle is simpler than you might think, but the effect is fairly strong.

Using a CO2 laser, it creates tiny thermal injuries in the skin,

and in the process, a very thin layer of skin tissue is removed.

The wavelength used at this time reacts strongly to the “water” in the skin, so it removes tissue precisely while momentarily vaporizing moisture.

Once this process passes, the skin begins to recover on its own.

In the dermis, collagen and elastic fibers are newly produced, triggering a response to fill in the damaged area,

and as a result, the skin texture becomes smoother and the scars gradually improve.

In other words, Fraxel is a treatment that improves the skin through a “remove → regenerate” process.

━━━━━━━━━━━━━━━━━━━━ 📌 Is it also effective for acne scar hyperpigmentation? ━━━━━━━━━━━━━━━━━━━━

Fraxel is not just a pigment treatment; it is a procedure that changes the overall structure of the skin.

So you can expect the following effects together.

The skin texture becomes smoother, collagen regeneration is induced, and acne scar hyperpigmentation also changes in the direction of gradually fading.

However, this process is based on the assumption that the skin will receive at least a certain level of stimulation.

So as much as it can be effective, it requires a recovery period and may be a burden depending on your skin type.

This is exactly the most important point when considering Fraxel.

━━━━━━━━━━━━━━━━━━ ⚠️ Why do Fraxel side effects occur? ━━━━━━━━━━━━━━━━━━

Fraxel is a method that intentionally damages the skin and induces regeneration.

Because of that, the following reactions may occur.

Redness may persist for a long time after the procedure, pigmentation after inflammation may become darker, and the skin barrier may temporarily weaken.

Also, for sensitive skin, breakouts may flare up again, or dryness, flaking, and delayed recovery may occur as well.

In particular, for skin that is sensitive to pigmentation, there are cases where trying to improve acne scar hyperpigmentation can actually make it darker, so caution is needed.

For this reason, at Shinchon Station Dermatology, whether Fraxel is appropriate is carefully judged according to skin type.

━━━━━━━━━━━━━━━━━━ 💡 A way to reduce the burden: Curejet ━━━━━━━━━━━━━━━━━━

If Fraxel’s strong stimulation or recovery period feels burdensome, other approaches can also be considered.

Recently, methods that induce collagen regeneration while minimizing skin damage have also been getting attention.

One of them is Curejet.

Curejet is a device that delivers medication deep into the skin using a high-pressure injection method.

Its biggest feature is that it can deliver active ingredients without using needles and without damaging the skin surface.

So even for sensitive skin or cases with pigmentation, it tends to be relatively less burdensome.

In particular, Juvelook, which is used together, (PDLLA-based collagen booster) induces collagen production within the skin

and plays a role in gradually filling sunken areas and areas with acne scar hyperpigmentation.

This approach is closer to “building up” rather than “removing.”

So you can expect a more stable improvement while reducing skin stimulation.

━━━━━━━━━━━━━━━━━━ ✔️ Features of Curejet ━━━━━━━━━━━━━━━━━━

Because it does not use needles, there is less concern about pain or bleeding, and you can return to daily life relatively quickly right after the procedure.

Also, depending on the skin condition, it can be adjusted in depth from the epidermis to the dermis, which is an advantage because it allows customized application.

Above all, because it does not shave away the skin like Fraxel, the possibility of redness or pigmentation becoming worse is relatively low.

For these reasons, it is sometimes considered as an alternative for people worried about Fraxel side effects or for those with sensitive skin.

In actual practice at Shinchon Station Dermatology, depending on the skin condition, this type of treatment may be used together or recommended first.

━━━━━━━━━━━━━━━━━━ 🙅 It is not possible in every case ━━━━━━━━━━━━━━━━━━

However, Curejet is also not suitable for every scar.

For hypertrophic scars or keloid-type scars, which involve excessive tissue growth, it may not be appropriate.

So the important thing is not the procedure itself, but an accurate diagnosis.

After sufficiently analyzing the current skin condition, choosing the most appropriate method is more important than anything else.

━━━━━━━━━━━━━━━━━━ 📝 Key summary ━━━━━━━━━━━━━━━━━━

Fraxel is a treatment that can help improve acne scar hyperpigmentation, but it also comes with stimulation and recovery burden.

On the other hand, Curejet is a method that induces collagen regeneration while minimizing skin damage, allowing for a gentler approach.

In the end, what matters is not which treatment is better, but which method is right for your skin.

━━━━━━━━━━━━━━━━━━

If you are considering a treatment method, rather than deciding based only on reviews or trends,

I recommend first getting 충분히 상담해보시는 것을 권해드립니다.

At Shinchon Station Dermatology, based on each person’s skin condition,

we help reduce unnecessary stimulation and focus on the treatment that is truly needed.

Your skin concerns, we will think them through and work to solve them together.

Thank you for reading. This was Kim Jang-ju.
