Picosecond (pico) lasers
Pico lasers deliver energy in extremely short pulses, breaking down pigment particles into smaller fragments that the body can clear more easily, and they're commonly marketed in Korea under names like Pico Toning or PicoSure-style treatments. These are typically used for melasma, sun spots, freckles and overall skin tone evenness, with a series of sessions rather than a single treatment usually recommended for visible results.
Excel V and vascular-focused lasers
Excel V is a specific laser platform generally used for vascular concerns -- redness, visible small blood vessels, and some types of scarring -- working on a different wavelength principle than pico lasers, which target pigment rather than blood vessels. This distinction matters because a treatment aimed at pigment won't meaningfully address redness, and vice versa, so the two categories aren't interchangeable even though both fall under the broad "laser treatment" umbrella tourists often search for together.
Matching the treatment to your specific concern
- Brown spots, melasma, freckles and overall dullness generally point toward a pico or similar pigment-focused laser.
- Visible redness, broken capillaries or vascular-pattern concerns generally point toward Excel V or a comparable vascular laser.
- Some clinics combine both in a single visit if your skin shows both pigment and vascular concerns -- ask directly whether combination treatment makes sense for you.
- Confirm the number of sessions typically needed and the interval between them, since laser pigment treatment is rarely a single-visit fix.
Skin type also factors into which laser settings a provider chooses, since darker or more melanin-rich skin types generally require more conservative settings to avoid post-inflammatory pigmentation -- a reputable provider will ask about your skin's typical sun response and any past reaction to laser or peel treatments before finalizing a plan.
