What should you know about CO2 treatment for stretch marks?

Stretch marks form when skin stretches and its deeper support structure changes. A CO2 laser can create precisely controlled areas of injury in or across the mark. As the skin heals, new surface tissue and collagen remodelling may soften uneven texture and reduce contrast. The result depends on whether marks are newer or older, their colour, width, location, and your skin's healing response.

Laser does not restore the skin exactly to its former appearance. A clinician should examine the marks and check for active irritation, recent tanning, medicines that affect healing, and a history of dark or light marks after inflammation. Pregnancy, breastfeeding, and plans for major body changes may also affect timing and expectations.

Ask whether the plan uses fractional CO2 energy, how the body area will be numbed, and what degree of peeling or downtime is expected. Avoid tanning and follow the advised skin-care routine before the visit. Tell the clinician about pregnancy, breastfeeding, cold sores, eczema, keloids, allergies, and all medicines or supplements.

After treatment, the area may be red, warm, swollen, tender, flaky, or crusted. Clean and moisturise it as instructed, avoid picking and friction, and protect it from sunlight. Do not apply acids, retinoids, fragrance, or unapproved home remedies to healing skin. Improvements emerge gradually, and more than one approach may be discussed.

Report worsening pain, spreading redness, increasing warmth, pus, foul smell, fever, or swelling that is becoming more severe. New blisters or a strong colour change should be assessed rather than treated at home. Seek urgent help for breathing difficulty, extensive facial swelling, or symptoms suggesting a serious allergic reaction.

Ask whether the marks are suitable for CO2 treatment, what change is realistic for their age and colour, and how your skin tone affects pigment risk. Compare the plan with fractional laser, microneedling, RF microneedling, or carboxytherapy, and clarify aftercare, sun protection, follow-up, and pregnancy-related timing.
