Q-Switched Nd:YAG for Pigmentation and Melasma

Pigment disorders are among the most frustrating concerns in aesthetic dermatology because they are visible, recurrent, and easily worsened by the wrong energy settings.

Q-switched Nd:YAG became important because it can break pigment with very short pulses and less unwanted heat spread than many older approaches.

1. Why this technology matters

The θεραπεια relies on short, high-energy pulses that target pigment particles and fragment them so the body can gradually clear them. This photoacoustic effect is especially relevant when we want pigment reduction without excessive thermal damage.

That does not mean every dark spot should be treated the same way. Melasma, solar lentigines, post-inflammatory pigmentation, and dermal pigment behave differently and need different expectations.

• melasma is usually chronic and relapse-prone
• sun spots often respond faster than melasma
• δερμα type changes both settings and risk discussion

2. Who is a good candidate

Patients who understand maintenance, strict sun protection, and the possibility of gradual rather than dramatic change are usually the best candidates. Pigment θεραπεια is often a protocol, not a one-time rescue.

Topical therapy, trigger control, and careful spacing may be just as important as the laser itself. Hormones, UV exposure, friction, and inflammation can all pull pigment back.

• SPF compliance is mandatory
• recent tanning raises risk
• combination plans often outperform laser-only plans

3. Recovery and long-term planning

Temporary darkening after θεραπεια can happen because fragmented pigment may rise toward the surface before shedding. This is not always a complication, but persistent darkening needs reassessment.

Melasma patients in particular should expect an ongoing control strategy that includes SPF, topical maintenance, and follow-up rather than a promise of permanent cure.

• short-term redness is usually mild
• maintenance often matters more than one strong session
• pigment recurrence does not automatically mean the θεραπεια failed
