What is a CO2 Laser and How Does It Work?
A CO₂ (carbon dioxide) laser is a powerful laser used in dermatology and aesthetic medicine for skin resurfacing, scar reduction, and collagen stimulation. It is an ablative laser, meaning it removes the outer layers of skin and stimulates deep collagen remodeling to promote new cell growth and improved skin texture.
This treatment is designed to address:
- Fine lines and wrinkles
- Sun damage and uneven skin tone
- Acne scars and other types of scarring
- Skin laxity (loss of firmness)
- Enlarged pores
- Rough texture and dull skin
CO2 lasers work by emitting high-energy light at a 10,600 nm wavelength, which is absorbed by water in the skin. Since our skin is made up of about 64% water, this makes CO2 lasers incredibly effective at vaporizing damaged skin while creating controlled micro-injuries that:
- Remove the outer damaged layers of skin.
- Trigger collagen production, leading to firmer, younger-looking skin.
- Encourage skin remodeling as new cells replace damaged ones.
As the skin heals, it generates new collagen and elastin, leading to a firmer, smoother, and more youthful complexion.
There are two main types of CO2 laser treatments:
- Fully Ablative CO2 Laser – Removes the entire top layer of skin. Best for deep wrinkles and severe sun damage but requires longer downtime.
- Fractional CO2 Laser – Creates microscopic perforations while leaving surrounding skin intact, leading to faster healing with similar benefits.
At Youthbar, we specialize in the Fully Ablative CO2 Laser.
What to Expect: Before, During, and After Treatment
Before Treatment: How to Prepare
To get the best results and reduce the risk of side effects, proper preparation is key:
✔ Avoid direct sun exposure for at least two weeks before treatment.
✔ Stop using retinoids, AHAs, BHAs, and exfoliating treatments 1-2 weeks prior.
✔ If you’re prone to cold sores, take antiviral medication before your session.
✔ Stay hydrated and follow any pre-treatment skincare regimen recommended by your provider.
During Treatment: What It Feels Like
✔ Procedure time: 30 minutes to 2 hours, depending on the area treated.
✔ Numbing cream is applied beforehand
✔ You may feel a warm, prickling sensation as the laser moves across your skin.
✔ Your provider will use cooling techniques to keep you comfortable.
Immediately After: The First 24-72 Hours
✔ Skin will be red, swollen, and feel sunburned.
✔ Some oozing and crusting may occur, which is normal.
✔ Tiny scabs or a grid-like pattern may appear as the skin heals.
✔ You may feel tightness and warmth for 24-48 hours.
✔ Keeping skin moisturized and protected is crucial.
Recovery Timeline
Days 1-3: Redness, swelling, and peeling begin.
Days 4-7: Skin starts to flake as fresh new skin emerges.
Week 2-4: Redness fades, skin looks brighter and smoother.
3-6 months: Full collagen remodeling results in firmer, more youthful skin.
Healing times can vary based on the depth of treatment, but fractional CO2 lasers generally have a faster recovery compared to fully ablative lasers.
What Results Can You Expect?
Your results will depend on your age, skin type, and treatment depth, but here’s a general breakdown:
Ages 20-30s: Refinement & Prevention
- Ideal for acne scars, sun damage, and texture concerns.
- Skin will appear brighter, more even, and refined.
Ages 40-50s: Rejuvenation & Wrinkle Reduction
- Noticeable improvement in fine lines, skin elasticity, and overall tone.
- Great for early signs of sagging and sun damage.
Ages 60+: Skin Tightening & Deep Wrinkle Treatment
- Helps reduce deep wrinkles and skin laxity.
- More dramatic improvements but longer healing time (10-14 days).
Post-Treatment Care: The Key to Stunning Results
Taking care of your skin after treatment is just as important as the procedure itself! Here’s how to maximize your results and minimize downtime:
✔ Stay out of the sun – UV exposure can cause hyperpigmentation.
✔ Use a gentle, hydrating moisturizer – Your skin will need extra nourishment.
✔ Avoid picking or scrubbing – Let your skin shed naturally.
✔ Drink plenty of water – Hydration speeds up healing.
✔ Skip intense workouts, saunas, and hot showers for a few days.
✔ Follow your provider’s aftercare instructions for best results.
Is CO2 Laser Right for You?
CO2 laser resurfacing is one of the most effective treatments for deep skin rejuvenation, but it’s not for everyone. This treatment may not be suitable if you:
❌ Have very dark skin tones (higher risk of pigmentation changes).
❌ Are pregnant or breastfeeding.
❌ Have active acne or skin infections.
❌ Have taken Accutane in the past 6 months.
If you’re unsure, we recommend scheduling a consultation at Youthbar so we can tailor the perfect skin plan for you!
