Sharing some of the lasers which I've done before:
1. Fractional co2 laser
An invasive type of laser. Mainly used to treat scars and pitted holes. Downtime is around 7 days. After the scabs have all fallen off, the skin was extremely smooth and the scars were lighten around 20%. Have to use sunblock as the skin would be more sensitive to sunlight after the laser. Recommend people with oily/ normal skin with scars/ pitted holes to try. I don't recommend for people with sensitive skin to try this.
Can just go for the cheapest one that you can find as this can be found at many aesthetics clinic. But be prepared for the long downtime.
2. Carbon peel laser
A layer of carbon liquid was applied onto the face before the doctor began the treatment. It's supposed to reduce oil production and tighten the pores. I didn't really see much result with this treatment. Might be due to the fact that I only went for 1 session and my skin wasn't too oily to begin with. No harm trying if you can try it at a cheap rate as I feel that this can replace facial.
Tried it at 1aesthetics @ west gate a few months back as it was rather cheap.
3. Dual yellow laser (aka combi laser)
It's a powerful laser but doesn't cause any discomfort. I use it mainly to treat my rosacea problem (skin flushes when it's hot). Have been doing this laser for around a year. Got to say that it controls my rosacea pretty well. For pigmentation, I don't feel that this laser works as well as the 2 other lasers mentioned above. Strongly recommend people with rosacea to try this laser as rosacea normally gets worse when we age.
Have been doing this at Drx clinic. Doctor was very nice to treat my entire face even tho the package that I signed was not for the whole face.
4. Skinbooster (aka 水光针)
This is not a type of laser, but it's a series of micro-injections that delivers hyaluronic acid 1mm under the skin surface. This is extremely popular in hk, tw and korea now. It's said that the many Korean actresses does this injection to get dewy skin. I've just tried this 3 days back. Can't really see the results yet. But for people who are interested, can google for simplistiq clinic @ marina bay link mall. This clinic offers the cheapest skinbooster (I know as I've called up most clinic that does the skinbooster to compare). They offer other laser treatments which are pretty cheap as well, but I've not tried them before.
Facial cannot treat ance/scars and at times it makes the condition worse when the beautician is inexperienced (speaking from personal experience). Furthermore, with aesthetics treatment becoming more and more affordable now, I strongly encourage you guys to try them out instead of going to facial.
