What should you know about Candela Nd:YAG laser?

The device delivers controlled light energy at a wavelength that can reach deeper skin structures. Depending on the settings and the clinical goal, it may heat hair follicles or selected blood vessels. A cooling method may be used to make the treatment more tolerable and help reduce surface heating. The same platform can be configured for different indications, so the name of the device does not by itself describe your diagnosis or expected result.

Tell the clinician about recent tanning, active rashes, cold sores, medicines that increase light sensitivity, and any tendency to form raised scars. Follow the clinic’s instructions about shaving, skincare products, and sun exposure. After treatment, protect the area from sunlight, use only recommended products, and avoid picking at crusts or blisters. Your plan may be aimed at laser hair removal or another targeted use; read about Nd:YAG Laser and Laser Hair Removal for context.

Contact the treating clinic promptly if redness or swelling is worsening rather than settling, or if you develop increasing pain, spreading warmth, pus, extensive blistering, or a fever. Seek urgent medical help for facial swelling that affects breathing or swallowing, or for a severe eye symptom after treatment near the eyes. Mild temporary redness or warmth can occur, but the clinician should assess symptoms that are intense, spreading, or unexpected.

Which concern are you treating, and why is Nd:YAG suitable for my skin and hair characteristics? What preparation should I follow? Which aftercare products are appropriate? What changes should prompt a review?
