If you live in Australia, you know all too well about the harshness of the sun and how it can affect your skin – particularly with regards to acne. The good news is there is a special treatment that can help deal with any acne scarring after it has healed – laser treatment. Any Australian laser clinic worth their weight in gold will offer this service given the reoccurence of the issue among Australians. The primary benefit of the treatment, as well as the drawbacks, is that it has an extremely precise effect.
How Laser Skin Treatment Works
Lasers can produce an intense monochromatic light that is limited to a narrow band of wavelengths. This typically won’t have an effect on some substances, whilst it will have a significant effect on others. One setting may be able to heat hemoglobin but have little effect on other neighbouring skin cells, whilst other settings might be able to ‘melt’ the melanin that can cause deep pigmentation on the skin. Australian dermatologists are able to use lasers to destroy specific substances at certain depths in the skin. The main effects of lasers in skin resurfacing are photothermal, heating particular substances in the skin. The process of using lasers to remove any blemishes in the skin is known as photothermolysis, which is the breakdown of selected tissues in the skin. Continually using laser lights on the target area would destroy tissue, which means laser treatment is typically done with pulsed lasers.
Continuing To Improve The Treatment Process
Laser treatment for any acne scars and brown spots began during the early 1980s. The early versions of the laser were used to heat the basal cell layer underneath the patient’s skin to prevent collagen production. The tissue above the treated layer of skin was charred and sloughed off, typically growing back without any scars or pigmentation. Scars would always return, however, this would occur about a year after treatment with this type of laser.
In the early 1990s, Australian doctors were introduced to the pulse dye laser. Treatment with this particular type of laser was targeted on hemoglobin. The top layers of skin were unaffected by the laser, with the hemoglobin in the blood underneath they only part that was heated. This pulse dye laser was able to keep the skin above the blood vessels from charring. It proved to be very effective for removing spots such as port-wine marks and purple skin discoloration, and, more importantly, any acne scars.
A third type of laser treatment – carbon dioxide laser ablation – could be used to remove any overgrowth of skin tissues lying on top of the scars. Australian doctors discovered that the key to getting the most effective results from laser treatment was to ensure the immune system didn’t send white blood cells to destroy any dead skin tissue. Any accumulation of the clean up cells known as macrophages has the potential to cause scars to form all over again. They found that laser treatments followed up by treatments with steroid creams were also effective in preventing swelling and malformation of new skin.
The Pros and Cons of Acne Laser Treatment
The significant advantage of acne laser treatment over earlier techniques of scar removal is that it involved little blood letting. Dermabrasion involved mechanically stripping off just the first 25 layers of skin cells right down to the section known as the ‘quick’, which is where the blood vessels were found. Regenerative skin cells underneath this layer have the potential to rise then fill in the scarred section as they replace the skin.
Dermabrasion typically left a bloody wound that could easily become infected. Laser treatment, however, works from the inside out without bleeding and with a significantly lower risk of infection. With every upside, there is a downside and the downside of laser treatments for acne has always been that undertaking one treatment is never enough to remove scarring. And certain skin types just do no respond particularly well to laser treatment.
Furthermore, the darker the skin is, the more melanin there is to absorb some of the light energey intended for hemoglobin. Any skin above the level of the capillaries serving the skin can char and potentially leave an open wound. When the skin eventually grows back, it may be lighter than the surrounding skin. The darker the skin, the greater the issue us with loss of pigmentation after treatment.
What Can You Do If You Want Perfect Skin?
What you need to know is that acne is not caused by one one factor, and it is not resolved by any one treatment. If you want a result of perfect skin, you will need to use a combination of treatments and techniques for months or maybe even for a few years. The point is that acne treatment is a long-term process rather than a short-term one. Regardless of the promises made by any websites and infomercials, there is no one technique that will get rid of your blemishes in less than one month.
