What should you know about CO2 laser for skin?

Carbon dioxide laser energy is absorbed by water in skin cells. Depending on the settings, it removes a very thin surface layer, heats deeper tissue, or combines both effects. The intended response can make roughness, fine lines, uneven texture, and some scars less noticeable as the skin repairs. The same heat can cause redness, swelling, sensitivity, crusting, and temporary changes in colour.

During consultation, mention active rashes, infections, cold sores, recent sun exposure, medicines, allergies, and a history of dark marks or slow healing. Arrange the cleansing and ointment supplies recommended for your plan. Afterward, touch the area only with clean hands, cleanse gently, keep it protected as directed, and avoid picking. Delay exfoliation, strong skincare, heat exposure, swimming, and direct sun until the clinician says the surface is ready.

A steadily worsening burn-like pain, spreading redness, increasing warmth, pus-like fluid, unpleasant odour, fever, or new blisters deserves prompt contact with the treating clinic. Get urgent help for severe facial swelling, breathing difficulty, or eye pain and vision changes.

Ask which skin concern is being targeted, whether the treatment is superficial or deeper, what healing stages to expect, which products are allowed, and how to reduce sun-related colour changes afterward.
