Non-Ablative Fractional Laser (Fraxel-type)

How it works

A fractional laser, such as a 1550 nm or 1927 nm system, creates microscopic zones of heat in the skin while leaving surrounding tissue untouched. The body replaces the heated columns over the following weeks, which may smooth texture, soften shallow scars and even tone. Some people see a bronzed look for several days. Results are gradual and vary by person.

Who it may suit

• Mild to moderate acne scars
• Fine lines and early photoaging
• Uneven texture and tone
• People who prefer shorter recovery than ablative lasers

The treatment day

1. Examination. The doctor checks scar type, pigment tendency, cold sore history and medications, then proposes a wavelength and density.
2. Numbing. Numbing cream is applied before the laser, which adds waiting time to the visit.
3. Treatment. The handpiece is glided across the face with built-in cooling. Heat and a prickling sensation are common.
4. Home care. Soothing products and instructions for the bronzed, rough phase are provided, and the next visit is scheduled.

Aftercare

• Expect redness and swelling for a couple of days
• Skin may feel rough and look bronzed as it sheds
• Use a gentle moisturizer and daily sunscreen
• Avoid scrubs, retinoids and strong acids until the doctor allows them
• Report blisters, pus or severe swelling

Things to know first

• Redness, swelling, dryness and a bronzed look are expected
• Cold sore flare-ups, acne-like bumps and pigment changes can occur
• Not generally advised with active infection, recent tanning or pregnancy
• Care is needed with darker skin tones and in people who scar easily
• Results are gradual, modest per session and vary by person

What to check before booking non-ablative fractional laser in Gangnam

Begin by asking which device is used and at what wavelength. The catalog lists Fraxel by Solta Medical as the named example, with wavelengths such as 1550 nm for texture and scars and 1927 nm for surface pigment. Many clinics offer other fractional systems under similar menu labels. It is reasonable to ask for the manufacturer and model, and for the clinic to explain how that choice suits your scar type.

Ask who selects density and energy and how they decide. Because the surface stays closed, this option is often described as having no real risks, which is not accurate. Look for a consultation that mentions pigment change, cold sores and the bronzed phase. Ask also how many sessions are expected, since single-visit promises are unrealistic for scars, and how the plan would change if progress is slow.

A clear quote lists the number of sessions, numbing, post-care products and follow-up. Be skeptical of very large courses sold before the first session. A good plan commits to a first session or two, reviews the response, and adjusts. That approach respects the fact that improvement is gradual and individual.
