Common Types of Laser Treatments
Medical aesthetic lasers are classified by wavelength and purpose into various types, with different indications. The following is neutral information without efficacy claims.
Lasers are classified by their target (absorption target)
The design principle of medical aesthetic lasers is to have specific wavelengths absorbed by specific 'targets' in the skin, then converted into heat or photoacoustic effects. Therefore, different lasers address different issues, and one machine cannot handle all conditions. Suitability must be assessed by a physician based on skin condition.
- Targeting melanin: mostly for pigmented spots and hair removal
- Targeting hemoglobin: mostly for vascular redness, etc.
- Targeting water: mostly for skin texture and surface renewal (e.g., ablative types)
Difference between ablative and non-ablative lasers
Based on whether the epidermis is removed, lasers can be broadly divided into ablative and non-ablative types. Ablative lasers have stronger effects and relatively more noticeable recovery; non-ablative lasers usually have milder recovery. There is a trade-off between intensity and recovery time, with no absolute superiority. Suitability must be assessed by a physician based on skin condition.
Frequently Asked Questions
What are the common types of medical aesthetic lasers?
Common types by purpose include pigment lasers, vascular lasers, ablative lasers, hair removal lasers, and picosecond lasers, with different wavelengths and mechanisms. Suitability should be assessed by a physician.
What should be noted before and after laser treatment?
Generally, it is recommended to enhance sun protection and moisturizing, and follow the physician's care instructions. Actual precautions depend on the treatment and individual skin condition as explained by the physician.
How long is the recovery period for laser treatment?
It varies greatly depending on the laser type and individual condition, ranging from no significant downtime to several days. Please follow the physician's instructions.
Is laser treatment a medical procedure? Does it require a physician?
Yes. Medical aesthetic laser is a medical procedure that must be performed by a qualified physician in a licensed medical facility; the devices are regulated medical devices that must be approved by the TFDA.
Are different lasers suitable for the same issues?
Different. Pigment lasers target spots, vascular lasers target vascular issues, hair removal lasers target hair follicles, ablative lasers improve skin texture, and picosecond lasers are mostly used for pigmentation and some texture issues. Suitability should be assessed by a physician based on skin condition.
