The scale most clinics still use was set out by Thomas Fitzpatrick in a 1988 paper in Archives of Dermatology on sun-reactive skin types I through VI. Its core is a pair of questions about the first strong sun of the season: how easily do you burn, and how well do you tan afterward? Color alone is not the test. Two people with the same shade can answer differently and land in different types.

Because the result rests on what you report, its accuracy depends on your memory. Think about a beach day after a winter indoors rather than your skin after weeks of travel. If you are unsure, say so; a doctor would rather hear that than a confident guess that sets the wrong energy.

Skin type matters most for heat and pigment. Lighter types tend to flush and sting; medium and darker types are more prone to dark marks after inflammation, known as post-inflammatory hyperpigmentation, and occasionally to lighter patches. The table summarizes common adjustments in general terms; the treating doctor sets the actual parameters after seeing your skin.

A recent tan raises the pigment load the laser meets, so the same setting acts more strongly than on untanned skin. Self-tanner and bronzing products change how the surface looks to both the doctor and the device. Mention either, even if it is fading.

Also mention any dark marks after past acne spots, scratches, waxing or earlier laser sessions. That history often predicts how your skin reacts better than the type label itself, and it is the detail visitors most often forget to bring up.

Days in this part of the city tend to be spent outdoors: street performances in the evening, walks along the Gyeongui Line Forest Park and afternoons at Mangwon Hangang Park by the river. That pattern suits sightseeing but works against freshly lasered skin, which marks more easily under strong light.

A few habits keep the plan on track. Book laser sessions early in the stay so redness can settle before photos, wear a broad-spectrum sunscreen and reapply it through the day, and choose a hat over long midday walks for the first days. After fractional or pico fractional work, which leaves fine crusts for several days to a week, keep the area out of direct sun until they lift.

A test spot is a small patch treated at the planned setting, usually somewhere discreet, then checked after a few days. It shows how your skin handles that energy in the short term and can reassure both sides before a full session.

It has limits. Pigment changes can appear later than a short stay allows you to see, and a patch on the jaw does not behave exactly like the cheek. Treat a clear test spot as a reason to proceed carefully, not as proof that the full area will respond the same way.
