Comprehensive Skin Laser Services: Pico, CO2, PDL and IPL at Siam Dermatology
A laser is a core technology in modern dermatology. It works on the principle of Selective Photothermolysis: energy at a specific wavelength is delivered to destroy a target such as melanin, hemoglobin or water in tissue, without damaging the surrounding tissue. Choosing the right type of laser for the skin problem, under the care of a specialist dermatologist, is important for both effectiveness and safety. At Siam Dermatology in Samut Prakan, we have several types of laser from leading manufacturers to cover a wide range of skin concerns.

Frequently asked questions
How do the different lasers differ? Each laser is designed for a different target. For example, Pico Laser is for melasma, freckles and tattoos, Fractional CO₂ is for acne scars and wrinkles, and PDL is for fine blood vessels and red birthmarks. The doctor chooses the type that suits each person's skin concerns.
Is there a long recovery after laser treatment? It depends on the type of laser. Some may cause peeling or scabbing for 5-7 days. During this time, avoid strong sunlight and apply sunscreen strictly.
