Hi,
The results of laser resurfacing for acne scars are permanent, so actually there is no need for further treatment to maintain the results if you are referring just to the scars themselves.
However, most of my patients would like to further improve their complexion (surface texture, skin glow, unclogged pores, fine lines, etc) in addition to the acne scar improvement they get from laser resurfacing.
In such an instance, a maintenance skin care regime tailored to your existing skin problem and skin sensitivity will be minimum that you should consider. Such a regime might comprise of a combination of sunscreen, AHA/BHA, vitamin C, retinol, retinoids, antioxidants and other products.
In addition, periodic “booster” procedures such as Rejuran Healer, HA skin boosters, laser toning, etc will help augment the results obtained from your initial laser resurfacing.
A thorough discussion with your preferred aesthetic doctor will help decide the appropriate maintenance strategy based on your needs, expectations and cost considerations.
Hope this helps!
