What is the best laser machine in Singapore for treating acne scars?

Good questions! I agree with Dr Chua’s reply on the pros and cons of Fractional CO2 lasers versus Infini RF. In addition, I would like to address your question on the ideal length of time between subcision and Infini RF treatments. The ideal interval between treatments is 4-6 weeks. This is to allow for adequate skin recovery. Hope that this answers your questions!

To address your questions: 1. Generally subcision (I assume with some collagen stimulators) will lead to collagen stimulation, and this is also what CO2 laser aims to do. Some experts suggest that an interval of at least 4 – 6 weeks is kept between each collagen-stimulating treatment for optimal results. There is no real good answer – as social downtime and other considerations have to be taken into account by the doctor in recommending the treatments. My personal preference though is not to stretch the treatment too wide apart – 6 months does seem to me to be a little long.
