Is it too soon for the Tretinoin cream? 7 wks after facelift and CO2 resurfacing.

Obviously, it is the laser resurfacing which may limit use of tretinoin during the recovery. Although your skin is not completely healed after 7 weeks, it is reasonable to start tretinoin cream or gel. You may find that your skin reacts with more irritation. If this is the case, decrease frequency of application, decrease concentration of tretinoin or stop entirely and wait a few weeks longer. Your surgeon and his medical team will guide you depending on your specific skin characteristics.

You are probably well healed at 7 weeks post op and this is likely an okay time to resume your skincare.  I still recommend you contact your surgeon to be sure as he or she has likely has specific post op instructions for you to obtain your best results.
