What should you know about Pentagon CO2 laser?

CO2 laser energy removes or heats targeted layers of skin, prompting a healing response and new surface formation. It may be used for texture changes, selected scars, lines, sun-related changes, or other concerns. The result and recovery depend on whether the treatment is ablative or fractional, the energy settings, the area treated, and your skin’s tendency to pigment or scar.

Redness, swelling, oozing, crusting, sensitivity, and peeling can follow resurfacing. Darkening or lightening of the skin, infection, prolonged redness, scarring, and cold-sore reactivation are possible. A name such as Pentagon does not tell you the laser settings or whether the plan is appropriate for your skin.

Arrange a medical assessment before treatment and disclose cold sores, active acne, eczema, psoriasis, recent tanning, pigment changes, medicines, and previous scars. Ask whether antiviral, acne, or pigment preparation is needed. Protect the area from sun and follow instructions about retinoids, acids, and other irritating products.

After treatment, cleanse and dress the skin exactly as directed, keep it moisturised, and do not peel or scratch flakes. Avoid unapproved cosmetics, heat, swimming, and direct sun while healing. Read about [CO2 Laser Resurfacing](/treatments/laser-and-energy/co2-laser-resurfacing/) and [Laser Skin Resurfacing](/treatments/laser-and-energy/laser-skin-resurfacing/) before comparing plans.

Call the treating team if pain, swelling, redness, or discharge is increasing, or if you develop pus, fever, spreading warmth, grouped blisters, or worsening eye discomfort. Seek urgent help for breathing difficulty, severe facial swelling, or vision changes. A treatment review is also needed for redness or pigment change that remains unexpectedly intense.

Ask which CO2 device and mode will be used, how deeply it will treat, who is medically responsible, what recovery looks like, and how your skin tone and pigment history affect settings. Ask about infection prevention, cold-sore precautions, expected discomfort, and alternatives such as [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/).
