In view of the highly sebaceous nature of the nose, in my experience, only fractional CO2 laser may give modest results after several treatments. Much has been written about fractional CO2 lasering in the Acne Scar Treatment section which you can refer to for more details about how it is done and usual treatment protocols and post-laser care and management.
Other usual acne scar treatment modalities such as subcision and TCA cross lend themselves poorly on the nose. Thus, it is best to avoid these types of scar treatments. It is important for you to consult a dermatologist or doctor to know which treatment is best for your condition.
