The before and after effects of CO2 laser treatment typically show significant improvements in skin tone, texture, fine lines, wrinkles, pigmentation, and acne scars. Patients often experience smoother, clearer, and more youthful- looking skin. Results are usually noticeable within 1 to 2 weeks as redness and flaking subside, with full improvements becoming more visible over several weeks to months as collagen rebuilds. CO2 laser resurfacing is effective for treating acne scars, sun damage, age spots, rough skin texture, and fine wrinkles. It works by resurfacing the skin, removing damaged layers, and stimulating collagen production beneath the surface. Multiple treatment sessions spaced weeks apart are often recommended for optimal results. After treatment, skin healing typically involves redness, peeling, and temporary lightening, with recovery times varying from days to weeks. The improvements seen in before and after photos illustrate less pigmentation, smaller pores, tighter and firmer skin, and diminished scar visibility, contributing to a revitalized and refreshed facial appearance. These outcomes depend on individual skin types, scar types, and treatment extent. In summary, CO2 laser treatment before and after images demonstrate substantial rejuvenation and skin quality enhancement through controlled skin resurfacing and collagen stimulation, with effects progressing gradually post-treatment.
