Resurfacing works on surface relief: enlarged-looking pores, a rough or uneven feel, and shallow scars that sit below the surrounding skin. Rolling, saucer-like marks with soft edges tend to respond more visibly than narrow, deep pits, which may need a different approach first.

It is a poor tool for loose skin along the jaw, seasonal brown patches or raised, thick scars. A careful doctor sorts the marks by type and depth at the first visit and says which ones resurfacing will barely touch. Improvement is gradual and partial, and results vary from person to person.

A fractional CO2 laser vaporizes thousands of tiny columns of skin and leaves bridges of untouched tissue between them, which speeds healing. The surface is broken, so fine crusting follows for several days.

RF needling pushes insulated microneedles into the dermis and releases heat at the tip. The face usually looks pink and lightly dotted rather than crusted, which many doctors weigh for skin that marks easily.

Nobari and colleagues, in a 2023 systematic review in Lasers in Medical Science, pooled 10 studies comparing needling methods, including RF needling, with ablative fractional lasers such as CO2 and erbium YAG for scars. The review found no statistically significant difference between the two approaches in 60% of those studies, and both produced marked improvement in many patients.

The authors described both methods as tolerable and safe. For a visitor, the device name matters less than the fit: downtime, skin tone, scar shape and the number of visits you can make tend to settle the choice.

A single resurfacing session fits one trip; a course usually does not. Sessions are commonly spaced about four weeks apart so collagen remodeling can show, which means most visitors plan one session per stay and continue at home or on a later visit.

Fractional CO2 tends to leave the most visible days, so many people book it early in a stay and keep the last days for sun-safe sightseeing. RF needling redness often settles faster.

• Day of treatment: warmth and tightness, like a strong sunburn
• First days: redness, then flaking with a CO2 laser
• Following week: pinkness fades; sunscreen and a hat outdoors
• Weeks later: texture change starts to show

Jalian and colleagues, writing in JAMA Dermatology in 2013, studied United States lawsuits over skin laser injuries. Failure to obtain informed consent was the most common preventable cause of legal action, and 61 of the 120 cases with a public decision went in the patient's favor.

Resurfacing carries real risks: burns, prolonged redness, temporary darkening, cold sore flare-ups and, rarely, scarring. A sound consent sheet names the device, the depth or density setting, the treated areas and these risks in writing. Ask who holds the handpiece and who sets the energy before numbing starts.
