Hello Krishna! thanks for the query.
There are various treatment options available for acne scarring ranging from chemical peel, derma roller and laser resurfacing etc. Please consult a dermatologist who will suggest the best treatment suitable for you.
You also mentioned about "holes leaking oil". This actually sebum which is produced by sebaceous glands. Hyperactivity of these glands produce excessive sebum (oil) and common in acne prone skin. Please wash your face daily with face wash containing Salicylic acid to improve this problem. Creams containing Retinoic acid are also useful in this situation.
Next Steps
