How Does the CO2 Laser Work?

At Dermatology Associates of Western Connecticut (DAWC) in Newtown, Connecticut, we use the advanced Tetra CO2 Laser to safely and effectively rejuvenate the skin. This laser delivers a focused beam of light that removes damaged skin cells and stimulates your body’s natural healing response.

As the laser creates precise micro-injuries on the skin’s surface, it triggers the production of new collagen and elastin—essential building blocks for firm, smooth, youthful-looking skin. The treatment can be adjusted for lighter, no-downtime sessions like CoolPeel or deeper resurfacing for more significant skin concerns.

Whether you're targeting fine lines, acne scars, sun damage, or uneven tone, the CO2 laser helps regenerate healthy skin from within. Patients throughout Newtown and the surrounding Connecticut communities trust DAWC for personalized care and exceptional results.

CoolPeel With Tetra CO2 Laser

CoolPeel is a cutting-edge, non-invasive treatment available exclusively through the Tetra CO2 Laser. It delivers the skin-renewing benefits of traditional CO2 resurfacing without the extended recovery time—making it an ideal option for patients who want visible results without major disruption to their routine.

This advanced treatment targets the superficial layers of skin to improve texture, reduce fine lines, minimize pore size, and brighten overall tone. By stimulating natural collagen production, CoolPeel leaves the skin smoother, firmer, and more refreshed with little to no downtime.

Tetra CO2 Laser Resurfacing

For patients looking for more dramatic improvement, the Tetra CO2 Laser also offers fully ablative and hybrid settings that penetrate deeper layers of the skin. This advanced resurfacing option is ideal for treating more pronounced wrinkles, deep acne scars, significant sun damage, and skin laxity.

By targeting deeper layers of skin, these treatments trigger a robust collagen and elastin response, leading to firmer, tighter, and more youthful-looking skin over time. While downtime is longer than with lighter treatments like CoolPeel, the results are more substantial and long-lasting.

At Dermatology Associates of Western Connecticut, we carefully evaluate your skin and goals to determine the best Tetra setting for your needs—delivering maximum results with expert care and precision.

TETRA CO2 LASER FREQUENTLY ASKED QUESTIONS

  • The Tetra CO2 Laser by Cartessa is an advanced skin resurfacing device that offers both ablative and non-ablative treatments. It’s fully customizable, allowing providers to tailor treatment intensity—from light touch-ups like CoolPeel to deeper resurfacing for dramatic rejuvenation. It treats wrinkles, acne scars, sun damage, uneven texture, and more.

  • CoolPeel is a signature treatment performed using the Tetra CO2 Laser. It’s a lighter, non-invasive option that targets the superficial layer of skin with little to no downtime. In contrast, deeper Tetra CO2 Laser treatments reach further into the skin to address more advanced concerns but may require more recovery time.

  • Recovery depends on the intensity of your treatment:

    • CoolPeel: Redness may last 1–2 days, similar to a light sunburn. Most patients resume normal activities immediately.

    • Moderate Resurfacing: Expect 3–5 days of redness, dryness, and light peeling.

    • Deep Resurfacing: You may experience 7–10 days of downtime with more visible peeling, redness, and tightness. This option is best for deep wrinkles or acne scarring.

  • Most skin types can benefit, but the best candidates are individuals with concerns like fine lines, uneven skin texture, acne scars, sun damage, or overall skin laxity. Our dermatology team in Newtown, Connecticut will assess your skin and recommend the ideal treatment settings for your goals.

  • For CoolPeel, patients typically feel a warm, prickly sensation but no significant discomfort. For deeper treatments, a topical numbing cream is applied beforehand. You may also feel some heat or tightness after the procedure, especially with more intensive resurfacing

  • This depends on your goals:

    • CoolPeel: A series of 3–4 treatments may be recommended for best results.

    • Deeper Resurfacing: Often just one session provides significant improvement, though touch-ups may be suggested.

  • CoolPeel results begin to appear within a week as skin becomes brighter and smoother. Full collagen-stimulating effects develop over several weeks. For deeper treatments, improvements in texture, tone, and tightness continue for up to 3–6 months as collagen production increases.

  • Yes. CoolPeel can often be combined with treatments like Botox or fillers for a full facial refresh. Deeper resurfacing may require spacing out additional treatments—our team at DAWC will guide you on the safest plan.

  • CoolPeel is safe for most skin types. However, deeper CO2 treatments may not be recommended for darker skin tones due to increased risk of pigmentation changes. We’ll evaluate your skin carefully before treatment.
