We are all obsessed with this baby skin. It is the skin that everyone is born with. But with time, the skin undergoes all kinds of insults from the environment and it starts to lose it pristine state.

What you do today, can improve all your tomorrows

What is a LASER?

The word “laser” is the acronym for Light Amplification by Stimulated Emission of Radiation. We are so lucky to be born in this age where this technology exist. It offers so much hope and potential to how our skin can improve with this technology. To be able to reap its full benefits, it is essential to understand the basic science behind this. Afterall, those who are apprehensive to this miraculous treatment are often lacking in knowledge of its facts.

The light that is produced from laser is different from the conventional sources such as lamps. Light that is emitted from a laser source is highly coherent and directional. Because of its single coherent characteristic, it carries high amount of energy capable of causing destructive damages to the target that it hits.

That is why there are legislation and rules in placed that it can only be operated by a trained professional. In Singapore, only a doctor is licensed to operate any laser class 3 and above.

 Laser can be produced in different “lasing” medium of which there are four common types: 

(a) Solid state (e.g. ruby crystal laser) 

(b) Gaseous state (e.g. CO2 laser) 

(c) Semiconductor (e.g. semiconductor laser) 

(d) Liquid state (e.g. organic dye laser)  

Thulium BB Aquatouch laser

I would like to talk about this particular laser which has taken the world by storm. The “lasing” medium of this popular “BB” laser is actually thulium. Thulium is a solid bright, silvery precious metal in the picture below.

This metal allows the laser beam to be projected at 1927 nm wavelength. This particular wavelength has a higher absorption coefficient for water than its predecessor, 1,550-nm Erbium glass laser. Since many of the pigmentation and dyschromia are at the basal level of the epidermis, it can treats pigmentation very well. A published research article done in korea looked at the effects of thulium on a patient with pigmentation problems particularly melasma, and its effect can be appreciated in the photo very nicely.

Split-Face Study Using a 1,927-nm Thulium Fiber Fractional Laser to Treat Photoaging and Melasma in Asian Skin by HYUNG MIN LEE, MD,1 SIK HAW, MD,†1 JAE KYUNG KIM, MD, SUNG EUN CHANG, MD, PHD, AND MI WOO LEE, MD

Additionally, the fractionated component of the laser allows for a spatially precise, regular pattern of columns of tissue injury to be created across the treated region, retaining the healing function of the epidermis even while targeting both skin layers. Through the fractionated treatment pattern that targets both the dermis and epidermis, these lasers provide the significant skin resurfacing capabilities of an ablative laser while retaining the downtime profile of a nonablative laser. However, because the laser can only target a fraction of the patient’s skin at a time, more treatments are typically required at 2 to 4 week intervals for the best outcomes.

Hence a program with about 6 sessions would be optimal to help you attain your skin goals better. Read more….
