Resurfacing lasers: What are they? How do they behave?
The name LASER is an abbreviation for “Light Amplification by Stimulated Emission of Radiation.” Radiation does not necessarily mean that it can damage your DNA or cells. Lasers are employed in the treatment of cancer to specifically eliminate malignant cells. Only one layer of the skin can be reached by laser radiation; any deeper layers cannot be reached. The interior organs of your body are therefore not harmed. Only the eyes are susceptible. As a result, eye protection should be used before the surgery. Dr. Jaishree Sharad discusses lasers in dermatology in detail.
Are Lasers Used For Hair Removal And Tattoo Removal the Same?
No, there are many types of lasers with distinct wavelengths for different therapies. For eliminating hair, one can utilise a long pulse Alexandrite laser or a long pulse Nd Yag laser. To erase tattoos, a Q-switched Nd:YAG or pico laser is employed.
How Many Laser Hair Removal Sessions Are Required for PCOS?
For hair removal, a woman needs 8–10 sessions, whilst a man need 12–15 sessions spaced 4-6 weeks apart. However, a girl’s reaction to the laser will be very gradual and laser sessions may go on forever if she has polycystic ovaries, elevated prolactin, testosterone, or even insulin resistance. Additionally, the reaction to the laser is minimal or nonexistent in guys using anabolic steroids or growth hormones. So, before undergoing laser hair removal, one must evaluate all hormone levels. Treat the hormonal imbalance, reduce your weight, and then anticipate fantastic outcomes. Otherwise, be ready to attend many sessions.
Before, During, and After Laser Hair Removal During Pregnancy?
There is no indication that laser hair removal may harm a developing foetus, making it an extremely safe technique. But before beginning the laser hair removal operation, it is preferable to speak with your doctor if you want to get pregnant. The hormonal changes that occur during pregnancy cause a woman’s skin to become more pigmented and her hair to grow faster. Since the effects of lasers can be unexpected and no studies have been done to ensure the safety of mothers and newborns, it is advisable to avoid using lasers while pregnant. After three months following delivery, when the majority of hormone levels have normalised, laser hair treatments can be resumed.
What Are Lasers for Resurfacing? How Do They Act?
Fractional CO2 and fractional erbium lasers are used for resurfacing. These lasers don’t do any harm. They damage the treated region in several tiny ways. Numerous growth factors are released by these tiny wounds, which lead to the reorganisation of existing collagen and the production of new collagen. The skin tightens and has an anti-aging effect as the collagen remodels. They cure acne-related scars or depressions as well as scars from accidents, burns, or surgery. They also lessen stretch marks, fine wrinkles, and open pores.
