What should you know about YAG laser hair removal?

Nd:YAG light travels into the skin and is absorbed by pigment around the hair follicle. This creates controlled heat intended to impair active follicles while sparing nearby skin. Hair grows in cycles, so treated hairs respond at different times and repeat visits are commonly needed. The method may be considered for darker skin types, but the device and settings still need individual adjustment.

Redness, swelling around follicles, warmth, or short-lived sensitivity can follow treatment. Hair removal does not diagnose the reason for excess hair. New facial or body hair may warrant assessment for Hirsutism, and recurring boils or tunnels need a different evaluation such as Hidradenitis Suppurativa.

Avoid tanning and tell the clinician about recent sun exposure, medicines, keloid scarring, active infection, and pigment changes. Do not wax or pluck the target hairs shortly before a session; shaving may be advised so the follicle remains available to the laser. Afterward, use gentle skin care, reduce heat and friction, and protect exposed areas from sunlight. Do not pick crusts or squeeze follicle bumps. Ask whether your concern is also linked with Ingrown Hairs or Razor Bumps, since hair-removal technique and skin treatment may need to be combined.

Call the clinic for blistering, severe pain, spreading redness, marked swelling, or new light or dark patches. Urgent assessment is appropriate for fever, pus, rapidly worsening tenderness, or facial swelling. A clinician can also compare options such as Alexandrite Laser or Diode Laser with Nd:YAG Laser for your skin and hair characteristics.

Why is Nd:YAG suitable for me, how will you test the settings, and what hair reduction should be realistic? Which medicines or skin products should I pause, and how should I handle a reaction?
