Acne scar treatment and microneedling in Hanoi

What it does, and what it does not

Fractional CO2 works by making controlled micro-columns of injury in the skin, leaving the tissue in between untouched so healing is faster. The repair response rebuilds collagen underneath the scar, which gradually lifts indented areas and evens texture.

It works best on rolling and boxcar scars. Narrow, deep ice-pick scars respond least to laser alone and often need a different approach first. Flat red or brown marks left by old breakouts are not scars at all — they fade on their own and do not need a laser.

Downtime — read this before booking

Expect the treated skin to be red and to feel sunburnt for two to three days, followed by fine flaking and a sandpaper texture for roughly five to seven days. Makeup goes back on once the flaking has finished, not before.

Strict sun avoidance for the following weeks is not optional. Skin that has just been resurfaced pigments easily, and a tan on healing skin is how a good result turns into a dark patch.

Do not book this in the week before a wedding, a shoot or a flight somewhere sunny.

Microneedling, and when it beats the laser

Microneedling works on the same principle from the other direction: instead of heat, very fine needles make hundreds of tiny channels in the skin, and the repair response lays down new collagen as they close.

It suits shallow rolling scars, early fine lines and skin that looks generally tired and slack. It is gentler than fractional CO2 and the recovery is a different order of magnitude — redness that usually settles in one to two days, in some cases two to three, rather than a week of flaking.

The trade-off is depth. On deep boxcar scarring the laser still does more per session. If your scars are shallow, or you cannot give up a week to recovery, microneedling is the sensible starting point — and we will tell you which of the two your skin actually needs rather than defaulting to the more expensive one.

Microneedling is priced on this site like everything else — the table below carries the real figure, pulled from the same system the studio bills from. Which of the three sessions suits you depends on what your skin is doing: Micro Acnes for skin still breaking out, Micro PIH for the brown marks left behind, Hydrapen where the issue is texture and slackness rather than acne.

Scartherapy, when one tool is not enough

Acne scars are rarely all one type, and the skin around them differs from person to person. Scartherapy is a combined session built around yours: once your skin has been looked at, we choose the combination that fits your scar types and skin condition, rather than running one fixed routine on everyone.

Plan for five to seven days of recovery after a session, and keep that week clear of anything where your skin needs to look its best.

A single session is priced in the table on this page. As a full course, Scar Away starts from 10,000,000₫ depending on your skin — how many sessions you actually need is settled at the free consultation, not before.

How many sessions

Scar work is slow. Improvement builds across sessions spaced roughly a month apart, and collagen keeps remodelling for months after the last one — the result at three months is better than the result at three weeks.

The honest framing is percentage improvement, not erasure. A well-run course softens scars substantially; it does not return the skin to how it was before the acne.
