ditto to the points made by Dr Lee and Dr Chua.
My only addition to this is that while clinical and histological studies do show *objective* benefits, the translation to visible results can vary.
Used in then long run, it is definitely a good maintenance procedure, but if you have doubts on it's likely visible benefits to your skin, it would definitely be best that you speak personally with your doctor - just to avoid any misalignment of expectations.
Happy CNY!
