I has CO2 laser on the 19th and my skin has peeled off, but the skin underneath looks like sandpaper. Is this normal? (photos)

I appreciate your concern. It is important to care for the skin as it heals with the right topical products. I would follow up with your provider to find out what you should be applying to the skin now as the outer layers have flaked off. An in-person assessment might also help you put your concerns to rest by ensuring your recovery is progressing as it should. 

Topical products are essential as the skin heals from this treatment. I encourage you to follow up with your provider to see what formulations are recommended for your specific situation. With the right after-care, you should be seeing that softer, smoother skin very soon!

I recommend following up with a cosmetic dermatologist for a formal evaluation and after care recommendations. I recommend skin care with vitamin c, b5 hydrator, silicone based scar gels with growth factors and enzymatic washes with papaya enzyme to give improvement. Sun protection is essential. Lasers like Co2 work best in combination with other treatments in order to improve the skin's texture and collagen. After Co2, I recommend adding fraxel lasers, microneedling/prp and radiofrequency treatments. Best, Dr. Emer
