Laser hair removal can be used on patients of just about all skin types, although it is most effective for people who have light skin and dark hair. 白色, blond or gray hair usually cannot be removed with laser hair removal since there is no pigment in the hair for the laser to target.
Although laser hair removal effectively slows hair growth, it does not guarantee permanent hair removal. Several treatments are usually required to remove hair. For best results, you may need at least six treatments spaced a number of weeks apart. Periodic maintenance treatments may also be needed.
Laser hair removal has become so popular that it is often performed in non-medical settings, 比如沙龙和水疗中心. It is important to choose a board certified doctor who is trained in laser hair removal to oversee the treatment.
准备
Before treatment, you will have an initial consultation at the dermatologic surgery clinic. 在咨询期间, the doctor or nurse will discuss your medical history and examine your skin. We will also examine the places you want the hair removed, 头发的质地和颜色, 以及它在成长周期中的位置. A laser hair treatment plan and its related costs will also be discussed, 以及任何相关的风险.
- Protect your skin from the sun with a broad-spectrum (protects against both UVA and UVB rays) sunscreen with an SPF of 30 or higher every day. 不使用晒黑床. If you have a natural or artificial tan from self-tanning products, your tan must fade completely before your laser hair treatment.
- 不要拔, 蜡, use dissolving creams or have electrolysis for at least one month before treatment. Shaving is okay as it leaves the hair root in place for the laser to target. Shaving may be recommended before treatment.
过程
Before treatment begins, the targeted area will be cleaned. A topical anesthetic may then be applied to the area to keep you more comfortable, 尽管很多病人并不需要它.
You will wear protective eye goggles during the procedure. The laser operator will hold your skin taut while the laser is fired. The laser beam will pass through your skin to the tiny follicles where hair growth originates. The intense heat from the laser beam damages the hair follicles, which stops hair growth. You may feel a stinging sensation or warm pinpricks.
The time of treatment will depend on the size of the area treated.
复苏
You may experience redness or swelling for the first few hours after laser hair removal. You may also have a stinging sensation for a day or two. The area may also become slightly crusty.
Do not pick or rub the area and be sure to clean gently with soap and water. Avoid sun exposure, both natural and artificial, for at least one week after treatment. It is also important to use broad-spectrum (protects against UVA and UVB rays) sunscreen with an SPF of 30 or higher every day.
