We have an acne scar package. The package that deals with depressed acne scars consists of the DNA Dermal Rejuvenation, secret laser and fractional laser treatment which costs 2 million KRW. Firstly, Co2 gas is injected to create a room for the recovery of the scar. Then the DNA self-corium will be injected to regenerate fibrous protein and fill up the sunken area. Also, the secret laser makes use of a pin needle which emits high frequency heat to cut off the tangled tissues that hold down to the skin and triggers regeneration of fibrous protein. Also, fractional laser helps to quicken the recovery process too. 

It really depends on the condition of the patient to decide the treatment plan. Normally it is ideal to have at least 3 sessions for overall improvement of the acne scars but you could still see the effects after one session.
