I. What exactly does laser do for the skin?
Lasers use specific wavelengths to deliver energy. Different types of tissue/protein/molecules such as hemoglobin or melanin (pigmentation), react to certain wavelengths. Once the laser reaches the skin, the targeted tissue is selectively destroyed.
Good and safe lasers can destroy only the targeted tissues without damaging the surrounding normal tissues.
And since there are so many different types of laser and wavelengths, it is up to the skill and experience of the doctor to select the right laser for your individual skin condition.
II. Common Misconceptions About Skin Lasers
1. Lasers will make your skin more sensitive and thin.
On the contrary, lasers promote collagen regeneration and will make your skin much healthier. However, choosing the wrong wavelengths may have adverse side effects and cause problems, which is why it's essential to consult a dermatology specialist beforehand.
2. Lasers have yo-yo effects; if you stop receiving treatment, your skin will become even worse than before.
Your skin will improve according to how much laser treatment you receive. Stopping treatment will not make your skin worse. The time and number of laser sessions will depend on your skin condition, so make sure to consult your dermatology to devise the optimal treatment plan. Some treatments require multiple sessions and are not easily treatable; so make sure you have realistic expectations before starting treatment.
III. Before Laser Treatment
1. Laser treatment is a medical procedure. Make sure it is performed by a certified and experienced doctor (dermatologist).
2. Make sure to thoroughly consult about the best laser for you, and discuss its realistic effects as well as potential side effects before selecting a treatment plan.
3. The following patients are advised to inform the doctor before treatment:
-Patients with diabetes, connective tissue diseases, conditions from radiotherapy or chemotherapy
-Patients allergic to local anesthesia or antibiotics
-Psychological disorders including alcohol or drug abuse
-Pregnant patients or expectant mothers
-Recent exposure to strong UV rays
-Previous skin conditions/disorders
4. Follow the orders and directions of medical staff for a safe procedure.
IV. After Laser Treatment
1. Follow the post-treatment guidelines provided by the clinic. Expected downtime is as such:
-Slight redness/swelling for a few days
-Crusting, slight blistering
-Heated or stinging sensation
These are normal responses to laser treatment. However, excessive pain or blistering, redness, swelling, infections/inflammation, burns, hyper/hypopigmenation, scarring, wounds etc. should be treated professionally; do not treat yourself and instead contact the clinic right away.
2. Here are typical guidelines to follow after treatment:
-Avoid alcohol and smoking to heal as quickly as possible.
-Avoid sauna or exposure to excessive heat
-Avoid anything that can irritate the skin (massage, scrubs, strong cosmetics)
-Get plenty of rest
-Avoid strong sunlight or UV rays
-Avoid extra skin procedures before your skin has healed completely.
