Dear Kele A picture is worth a thousand words and would be very helpful here to know exactly what you are talking about. CO2 Laser resurfacing creates a profound thermal injury of the skin that must be healed. This can take many months to resolve. However, it can also be indicative of the formation of a subdermal scar. Your treating surgeon should be closely monitoring your progress. When the subdermal collagen formation, which is a necessary part of why laser firms the skin, is too much, scar and excessive skin contraction can occur. This type of reaction can be modified with 5-FU, topical and injectable corticosteroids if necessary. Persistent inflammation in the skin can also lead to post inflammatory hyperpigmentation which may need treatment. I would encourage you to contact your treating surgeon can discuss your concerns with that person so you can be reassured or, if necessary, treated.
