Home Nd:YAG laser devices

Nd:YAG refers to a laser medium that produces a specific near-infrared wavelength. In dermatology, this energy can be selected for a target such as hair pigment or certain nail changes, while the surrounding skin is protected as carefully as possible. Results and risks depend on the device, settings, skin tone, target, cooling and operator technique. Read about [Nd:YAG Laser](/technology/nd-yag-laser/) to understand the technology.

Do not use a home laser over a changing mole, tattoo, open wound, active infection or recently irritated skin. Check the manufacturer’s intended use and eye-protection instructions, and never improvise with a device marketed for a different target. Avoid tanning around treatment and tell a clinician about medicines that increase light sensitivity. Clinic procedures such as [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) use assessment and controlled settings. Nail discoloration also needs diagnosis before considering [Laser Treatment For Nail Fungus](/treatments/laser-and-energy/laser-nail-fungus-treatment/), because trauma and other nail diseases can look similar.

Stop using the device and seek medical advice for blistering, severe pain, spreading redness, pus, lasting pigment change or any visual symptom. A changing pigmented spot should be assessed rather than treated at home. Arrange review before further sessions if hair growth, nail changes or skin marks do not match the device’s intended indication.

Is this device appropriate for my skin tone and target? What area should be avoided, what eye protection is required, and how should a burn or pigment change be managed?
